Why do I have AVIF files?
More and more websites serve images as AVIF because the files are small and load fast. When you right-click and save a picture, you get a .avif file, and then the app, upload form or printer you wanted to use won’t take it. Converting to JPG fixes that: JPG works in every app, email and online form.
How to convert AVIF to JPG on Windows and Mac
Windows: the Photos app can show AVIF once the free AV1 Video Extension is installed from the Microsoft Store, and Paint can then save a copy as JPG. Mac: open the image in Preview, choose File → Export, and pick JPEG. For more than a couple of files, this page is faster: drop them all in and download one ZIP.
Getting the best JPG
Leave quality at 92% for photos you’ll share or upload. Use 100% for printing or for images you’ll edit again. If an image has text, sharp lines or a transparent background, the AVIF to PNG converter will look cleaner.
