Sometimes it’s easier to visualize the contents of a video file with a sequence of thumbnails or still images. Here’s a quick, easy, and free way to extract JPGs at intervals from a video file.
JPEGmini promises that their proprietary algorithm can dramatically reduce the size of JPGs with no discernible loss in quality. So I put their secret sauce to the test.
WebP is an emerging image format that is designed to create images that are visually indistinguishable from JPGs (or PNGs) but with much smaller file sizes. That in turn makes for a faster website.
