Panoramas can make for a fun and interesting option for capturing photos. Whether you’re capturing for a specific aspect ratio output such as wall display piece or website header, looking to incorporate a lot of visual data in the image, or just aiming for a different view, panoramas can be a creative approach. Personally, I’m a fan, and I’ve been shooting them for many years. By capturing a very wide–or, for that matter, tall–field of view, they can be dramatic. And they can be revealing, by adding context.
They also bring with them some challenges. Among those is how you take multiple images and stitch them together into a single panoramic image.
Some newer cameras and smartphones have an automatic panorama setting built in where you can sweep the camera around the view and it’ll all be stitched together in the camera. But as convenient as that is, you often don’t get much control over the finished product and the resolution is often much lower than you might expect from the camera’s usual capabilities. You can often get much better results, and infinitely more flexibility, by taking a series of individual, overlapping images that you then later stitch together using software.
There are quite a few different software options that can stitch panoramic images. They range from full-featured dedicated apps that give you an enormous amount of control and that produce very professional results, to lightweight free apps that can get the basic job done but don’t give you much control. And some of the most popular image editing apps have panoramic stitching capabilities built in, even if it’s not always obvious they’re there.
So here’s a rundown of some of the better options for panorama stitching apps, ranging from simple, free apps, to much more powerful, paid ones.
The ones I’m focusing on here are still image, flat panoramas. There’s quite a lot of overlap in software and technique between flat panoramas and 360° virtual tours, but there are some specific requirements when shooting and displaying the latter. Regular flat panoramas–still images that have a very wide or tall aspect ratio–are what I’m focusing on here.
Free Panorama Stitching Software | Dedicated Apps
The best panorama apps tend to be paid ones, and not inexpensive at that. But there are also some free options available. Overall, their features tend to be pretty limited and their user interface is not particularly polished. But if you’re dabbling or just have a one-off need, they’re a useful place to start.
Hugin
If you’re after something straightfoward to use, free, and cross-platform, take a look at Hugin.
It’s built on a set of underlying software called Panorama Tools, a suite that some of the other apps here are also built on. There has been steady development that has been building the app out to a stable release. Early versions were quite basic, but the developers have since added more sophisticated capabilities such as being able to manually tweak control points and projection.
Its interface is functional but not slick or especially refined, but it it does what it needs to do. Hugin is free and there are versions for Windows, Mac, and Linux.
AutoStitch
AutoStitch is focused mostly on the underlying algorithm that is then licensed to other software manufacturers to use in their apps. But they have also put together a rudimentary front end for it. It’s very basic, and you don’t get any control over things like editing control points or choosing the projection, but it’s simple to use and it’s free. There are versions for Windows and Mac.
GigaPan Stitch
If you’re shooting with a GigaPan panoramic robot, there’s a dedicated Gigapan panorama stitcher available called, oddly enough, GigaPan Stitch.
Overall, it’s fairly basic and quite outdated now, but one thing it does especially well is multi-row (or multi-column) panoramas, which is a bread-and-button feature of the GigaPan robots. But if you’re not shooting with a GigaPan or uploading the stitched images to the GigaPan site, there’s not much reason to use their GigaPan Stitch–there are much better options available. And even if you are shooting with a Gigapan (in which case you’ve already made a significant investment in panorama shooting) don’t feel as though you have to use their software–other options like Hugin and PTGUI Pro work even better and give you more flexibility.
You can download GigaPan Stitch here. There are versions for Mac and Windows.
Microsoft ICE
ICE, which stands for Image Composite Editor, is a product of one of Microsoft imaging research labs and is a good complement to the PhotoSynth technology. It has some unusual and really interesting features, like being able to create a still image panorama from a video pan and compositing images in ways that most stitching apps can’t. But it doesn’t have the end-user refinement of some of the other apps here–it basically feels a bit experimental, which is precisely what it is, of course. ICE is Windows only, free, and available as a standalone program or as a plugin for Photoshop.
Paid Panorama Stitching Software | Dedicated Apps
PTGUI Pro
PTGUI Pro is my go-to panorama stitcher, and it’s one of been using for over a decade. It started as a graphical user interface for some underlying command line tools known as PT Tools–hence the name PTGUI. But over the years it has grown enormously and offers a wealth of powerful options in everything from masking out unwanted elements, manually editing control points, straightening horizons, and working with very large and multi-row panoramas.
Its user interface is another that falls in the functional but not pretty categories, and there is a bit of a learning curve to get the best results out of it. But if you want maximum control over your panoramas or are shooting them professionally, it’s hard to beat.
There are versions for Windows and Mac. Paid license, with free trial version.
Panorama Stitcher Mini
Available from the Mac App Store. There’s a free version that’s limited to 5 images; if you want to stitch together more images than that, you’ll need to upgrade to the Pro version.
Overall, it’ not in the same league as PTGUI Pro, but it is also a lot cheaper. Mac only.
Free Image Editing Software that Includes Panorama Stitching
These apps don’t have panorama stitching as a primary objective, but they either have the capabilities already built in or can be extended with plugins to add them.
GIMP. GIMP is an open-source and free image editing app. It’s surprisingly powerful and is backed by a dedicated and committed development community. It’s often seen as a good free alternative to Photoshop.
GIMP doesn’t natively support panorama stitching, but you can get plugins that add the functionality, like Pandora and this one.
Paid Software that Includes Panorama Stitching
Again, these apps don’t have panorama stitching as a primary objective, but they either have the capabilities already built in or can be extended with plugins to add them.
Lightroom Classic
If you’re already using Lightroom, you already have a very effective panorama stitcher baked in. You don’t get much control over the process, but in many cases, the stitching engine works very effectively with excellent results. And there’s a lot of convenience in having it so readily accessible in the place where you’re managing and editing your images.
Lightroom is a paid app for Windows and Mac and has a trial version available.
Photoshop
Photoshop is the gold standard of image editing apps, and one of its numerous features is that it can stitch panoramas. It doesn’t make much sense to buy Photoshop just for the panorama stitching option (called Photo Merge), but many of us already have it installed. And it’s quite a powerful and effective option for this task.
Photoshop’s panorama stitcher works very similarly to the one in Lightroom–they share underlying engines and algorithms. If you’re already using Lightroom, it can be more convenient to use the one there. If you’re not using Lightroom, Photoshop’s version will give very similar results, although it does give you more options. One I particularly like is the option to use the Content Aware Fill feature as part of the photo merge process to fill in transparent areas–it can work really well in some situations.
Photoshop is available for Windows and Mac and is a paid app with a free trial.
Misc Notes
Some of these apps support RAW files, but many don’t. If you want to work directly with RAW files–and there are some advantages to doing so–you’ll need to make sure the app supports the format. Lightroom is an example of one that supports working with RAW files directly, and it even outputs the stitched panorama as a RAW file (DNG format).
Not Recommended
Panorama – Perspective Image Stitcher. This Mac app looks on the surface to be good, but it doesn’t work well for stitching more than three images at once. If you want to do a panorama with more tiles than that, you can technically stitch them in small batches and then stitch the resulting mini-panos, but that’s a really poor way to do it. Users have also reported that its merging algorithm also leads to substandard results.
Canon PhotoStitch. While it’s put out in support of Canon cameras, it’s not limited only to working with images shot with a Canon. But there’s not a lot else going for it when there are much better options available. Windows only.
No Longer Available
Kolor / Autopano Pro, AutoPano Giga. For a long time, the various Autopano products put out by color were among the best in the business, with powerful stitching apps that gave a lot of control over the whole process. But Kolor closed down in 2018, and their Autopano products are no longer available.
iFoto Stitcher. It was pretty basic, but had two notable aspects: it made it very easy to work with multi-row stitching, and it had good built-in tools for sharing panoramas on social media. It’s no longer available the Mac App store.
Recommendations
If you’re after the best free panoramic stitching software, start with Hugin.
If you’re after the most powerful panorama stitcher, take a look at PTGUI Pro.
If you’re already using Lightroom Classic, it’s worth giving the built-in Photo Merge function a try–you might be surprised at how effectively it works for such a simple-to-use tool.
And, as always with any of these, the results you get out are directly related to what you feed in. Carefully captured images with a reasonable amount of overlap and minimal perspective shift are much more likely to yield good results than rough shots where the camera moves. If you’re finding that the automatic alignment of one of the basic apps isn’t working, it’s worth trying something more powerful such as Hugin or PTGUI because they have tools that let you manually tweak alignment points and even mask out parts of an image where things have moved, such as people in a crowd.
Ajith Wickramasinghe says
I wanted to know about the algorithms separately used by above stitching software for image stitching process. There are various direct and feature based techniques available for that. Some examples are SIFT, SURF descriptors under feature based techniques and some key point detectors such as Harris. Actually I am doing a research on enhancing available techniques used by software. Therefore, I need to know particular techniques / algorithm used by above software. If any one have an idea, pls help me to send the details of them
David says
Sorry, but I don’t know the answer to that. Your best bet might be to contact the developers for the individual apps directly.
Søren Theilgaard says
I think it would should be mentioned that Affinity Photo (The Photoshop alternative) is also capable of panoramas, though it is limited in control (https://affinity.serif.com/en-gb/photo/)
David says
Thanks for the tip. I’ll check it out.
PavelH says
Unfortunately Affinity stitching does’n work on iPad. It will work for some small number of low-res pictures.
As soon as you try to add more high-res pictures it will crash.
BC says
Thanks for a helpful article. I’ve now learned of so many options.
I’m curious if you have computer hardware suggestions for effectively assembling pianos?
I recently assembled a 20 shot stitch on a 10 year old Mac Pro. LR had to run overnight to create a 2x 10 row pano, 220 MPs.
David says
It’s not really something I’ve tried benchmarking, sorry. I do find that Lightroom’s stitching gets very resource hungry. For bigger and more complex stitching, I tend to reach for PTGUI Pro, which seems to take it more in stride. But I don’t have any numbers to put to it.
alex hamberg says
Hello David, iFoto Stitcher is not available any more. But you can get all similar features from WidsMob Panorama. The program can help users stitch JPG and RAW automatically and smartly.

Hi can you recommend a way I can burn photo’s after adding them to a timeline? I would like to put them on a dvd-r and watch them on a TV from a dvd player. Many thanks.
David says
I’m not sure what kind of timeline you’re adding them to, but you’ll want to have access to them directly on your hard drive, so you might need to download them first. Many of the DVD-burning apps have an option to burn a photo DVD, which creates a multimedia version that you should be able to play on your DVD player. But to confirm compatibility with your DVD player you’ll need to check with the specific app. If you don’t want to mess with the DVD burning apps yourself, some of the online photo services have photo DVD products where you upload the photos and they’ll take care of the rest and mail you the finished multimedia DVD. I haven’t used any of the online services specifically for this, but somewhere like Shutterfly would be a good place to start.
Eric Shambroom says
Hi! I’m desperately searching for professional 360 degree video software. Now that Kolor is dead do you have any suggestions?
David says
Sorry, I don’t. I stick mainly to stills when doing 360, and if I do use video it’s quite basic. Sorry I can’t be of more help.
Barrie says
Check the Kuula VR360° website for info. The old Panorama Factory I still use for standard pano’s does 360° stitching and is still available online.
Barrie says
Good range of software here David – thanks for the info. I am still using John Strait’s Panorama Factory (PF 5.3 M32), previously with my Sony F828 and now with the RX10. Outdated software yes, but I still find it does an excellent job of stitching my (mostly) hand-held pano’s. The software hasnt been updated for something like a decade now which is a pity, but I do find it very intuitive, easy to use and it generally makes a good job of amorphous surfaces like cloud, sky and water, with manual mode for problematic image matching. Down the line I’ll probably look at 64bit PTGUI or Lightroom when I next upgrade my PC, and the RX10 has good built in panos as well.
B.B. says
Hi can you recommend me a free one in your post that can also handle adjusting contrast in photos? I would like to find the abilities of photoshop for only stitching and contrast editing only but not purchase light room or the full blown photoshop. Thank you!
David says
The one that comes immediately to mind is Gimp with one of the various panorama stitching plugins such as this one or this one (I haven’t used either of them, so I’m not sure which works better).
yuval says
Great article overall though perhaps you didn’t know but PTGUI is using the same engine as Hugin (i.e. PanoramaTools) and also i don’t know when did you wrote article but Hugin have masks now and probably the most control you could possibly get with doing the job by hand, which is a feature in Hugin.
I really recommend you try, trust me it will be worth your time.
http://hugin.sourceforge.net/tutorials/index.shtml on that page you find a bit of Hugin’s capabilities.
Sorry about the rambling it just i really don’t like it when people disregard programs just because they are free.
David says
Thanks for the heads up. I’ll give it another look–it’s been quite some time since I used it.
Andy Bobyarchick says
Kolor (Autopano) is out of business.
David says
Thanks for the heads up. Have updated above.
Kenn Rabin says
Thanks so much for this overview. I’m sending the link to my pano-buddy, so we can discuss. I have been doing flat-field 180 degree panos, primarily, usually using about 40 tiles, in 3-4 vertical rows. I use the manual Nodal Ninja pano head and am very happy with it. Just wanted to share my experience and perhaps pose a question to everyone: I have primarily been using PhotoShop’s Photomerge and PTGui. I actually find PhotoShop does a better job, basically, but of course it doesn’t have much flexibility at all. My big problem (and it IS a deal-killer) with PTGui is that it massacres water (lakes, etc.) in terms of stitching, and also can’t handle time-exposure tiles at all well (again, especially when I’m trying to blur running water). Basically, it’s water-repellent! I was thinking of trying Autopano Gig but before I plunk the money down, I wondered if you (or any of your readers) could comment on the stitching engine’s strengths and weaknesses, as compared to PTGui and PhotoShop. Any thoughts?
David says
Yes, water can be an issue, for sure. I tend to use Lightroom’s or Photoshop’s pano stitching for simple, straightforward jobs, but PTGUI is so much more powerful. I particularly like its masking and alignment point customization tools. The masking comes in particularly handy when there are moving objects in the frame (eg. people or cars), and being able to specify the alignment points manually–or at least, tweak them–comes in very handy when it wasn’t shot with a pano head/tripod. It’s been a while since I used Autopano Gig, so I’ll have to refresh my memory and take a look at the latest version.
Owen says
Hi,
Some really interesting reviews – they will save me a stack of time trying (and finding!!) different stitching programs. My application for stitching is sourced from video, and I’m going to experience the problems mentioned by Christopher : having to deal with different angles, distances, and to add to the mix, zoom levels. One of my problems will be I have a wide shot showing the entire scene and then zoom to the detail (and pan over the detail). So I’d like a result image set to the pixel size of the ‘zoomed in’ area, but interpolates the crap out of the ‘zoomed out’ area to fill in the less important context areas… a bit like the way ICE can do autocomplete except using the real image (in interpolated quality) rather than what microsoft thinks is there.
Could you add a review of the “Zoner” application Christoper talks about? It sounds as though it might be able to do what I want (even if I have to extract video stills to do it).
David says
Will see what I can do!
David Ruddle says
Hi. Is it OK if I link to this article in my blog on Panoramas?
David says
By all means.
Christopher says
Until recently, I had a Nokia Lumia 1020, a smartphone with a Ziess lens that produced 38mp images. I’m curious, since I’m on a budget, what differences there would be if I “downgraded” to a 24mp DSLR or mirrorless. They are smaller files, which means for the same size panorama I would need to take and stitch more files, but hypothetically a newer mirrorless should get better quality images. So basically my question is, at what point does it become unrealistic to stitch together multiple tiles? I’ve done 3-5 image panoramas with that smartphone camera and got pretty good results using Zoner Photostudio, but seems like no matter which software, each stitch eliminates a small amount of each photo and the resulting panorama. I’ve managed to stitch together a collection of nearly 100 images (macro shots of a moth wing), but it was messy. I tried using ICE to do multi-row stitching and it was terrible, probably because I took the photos by hand without much control over angles and distances, but Zoner managed to stitch the 3-5 enormous rows into a single, 5ftx5ft collection that I could then paste sections of undistorted images over an ugly stitches.
Mike Nelson Pedde says
There is much more to life than MP. Your phone may be 38MP, but the sensor is about the size of your baby fingernail. If you move to a DSLR you will gain, not lose. There’s too much to this to cover in a single comment, but if you search online you’ll find lots. As far as stitching a given scene, this varies depending on the focal length of your lens and the sensor size of your camera combining to give you a specific field of view. The lens on your phone gives you a (full-frame equivalent) focal length of about 26mm. If you use a wider or longer lens on your DSLR you will have a different field of view and may need more or fewer images to cover the same area.
Santi Maspons says
What about IOS apps?
David says
Fair question. Because iPhones have the built-in real-time panorama function I use that if I want to shoot a quick panorama on the iPhone. But when I need much better quality and higher resolution I always use photos shot with a larger camera like a DSLR or mirrorless. So I haven’t investigated iOS apps that stitch individual photos. A quick search shows that they definitely exist, and I’ll try to test some of them out, but not sure when that will be.
Dave C says
I’ve tried as many as I can find and none do I better job than using the pano feature in phone or in a camera. There was a fantastic app called AutoStitch which used the AutoPano engine and it was excellent. Imported a dozen plus pics from my dslr on to the Ipad and it would just stitch them perfectly. This is not the app currently called autostitch, in fact google bought the original app and incorporated it into google photos, but they don’t allow a user to make a pano. It just occasionally presents one from uploaded photos. Nothing comes close to that on the app front now.
Ron says
Hello,
Do any of these applications include injection Facebook 360 Metadata and file conversion options for the FB standard of 2:1 aspect ratio, with maximum file dimensions of 6000 x 3000 pixels?
Thanks
David says
The 2:1 is standard equirectangular for any 360° video. It’s a standard feature of many of them–I use PTGUI for it. Pixel dimension resizing can be set in output. Off the top of my head I can’t think of any that inject the metadata into still panoramas by default, but I also have looked into this specific issue.
derfrankie says
Hi, great overview – there is still Microsoft ICE out there for free – also a very good option, Windows only

Thanks for the tip. I’d forgotten about that one–will add.
