We ran our reference photo, a screenshot of our pricing page and a piece of flat art through one engine and kept the bytes. AVIF made the smallest file on all three, 55% under the JPG on the photo, and WebP came second each time.Sahadat Husain

Here is what we measured, what libvips really does with the file, and the one kind of JPEG that stays out.Sahadat Husain
