AVIF to JPG and AVIF to PNG: three free ways, and a whole folder at once

Install the free AV1 Video Extension from the Microsoft Store, open the file in Paint and choose File, Save as, JPEG picture. For a whole folder, drop it on Convert Images in AwaCut.

Yes. Convert Images in AwaCut converts a folder in one run on Mac, Windows and Linux. With ImageMagick: for f in *.avif; do magick "$f" "${f%.avif}.jpg"; done.

A little, as every JPG does. At a high quality setting you will not see it. Choose PNG to keep every pixel.

On a Mac, yes: Convert Images in AwaCut reads HEIC and writes JPG, a whole folder at once. On Windows and Linux it does not read HEIC. For a single photo on a Mac, Preview also exports HEIC as JPG for free.

The same way: drop the WebP files or their folder on Convert Images, pick JPG and export. JPG has no transparency, so for WebP images with a transparent background choose PNG instead.

WebRip is a video copy, not an image format, so no image converter opens it. Save a frame with your video player first, for example with Take Snapshot in VLC. If you meant WebP, Convert Images turns a folder of WebP into JPG in one run.

Portable Network Graphics is the full name of PNG. Drop the PNG files or their folder on Convert Images and pick JPG. JPG has no transparency, so transparent areas get white or a colour you choose.

Yes. Convert Images reads TIFF and BMP on Mac, Windows and Linux and writes JPG, PNG, WebP or JPEG XL, a whole folder at once. The first 10 photos are free, then one yearly licence covers as many as you want.
