Convert AVIF to JPEG on Mac
Select the AVIF files in Finder, press ⌥ F, choose JPEG and press Return. FileFlip saves each JPEG next to its original and works without an internet connection.
How to convert AVIF to JPEG with FileFlip
Select the AVIF files
In Finder or on the Desktop. One file, or a whole folder with ⌘ A.
Press ⌥ F
FileFlip opens next to the selection and lists the formats it can make from AVIF. Type “JPEG” to jump to it.
Choose JPEG and press Return
The JPEG files appear next to the originals. To make them smaller first, press ⇥ and lower the quality or size.
AVIF and JPEG
AVIF is still new, so plenty of apps and upload forms can’t open it. JPEG opens everywhere, from email and websites to Windows PCs and photo printing services.
What changes when you convert
- JPEG is lossy: the file gets much smaller and some fine detail is discarded. At high quality settings the difference is hard to notice.
- JPEG can’t hold animation, so an animated AVIF becomes a single still image.

For one file now and then you may not need FileFlip. These work with what’s already on your Mac.
Preview
Open the AVIF in Preview, choose File → Export, pick JPEG from the Format menu and click Save. For several files, open them together, select all thumbnails in the sidebar and choose File → Export Selected Images.
Good for a few files now and then.
Terminal
The sips command converts images in place or into a new file.
sips -s format jpeg image.avif \
--out image.jpgBuilt into macOS and good for scripts. Run sips --formats to see what your macOS version can read and write.
