There’s a bunch of different image formats available, some old as well as many new ones. But it’s not always clear which is the best to use. JPG? RAW? HEIC? WebP? Here’s a quick guide on which image files formats are best, when.
If you’re looking to manually create WebP versions from JPGs (or any other image file formats, for that matter), XnConvert is free, multiplatform, and is especially good at handling large batches of images.
If you use a lot of images on your WordPress site and are serious about speeding it up, image optimization is a great place to start and can give some really impressive gains for very little work or expense.
