Why you keep running into AVIF files

AVIF is the newest web image format - sites use it because it's tiny, and browsers display it happily. The trouble starts when you save one: image editors, Office documents, older viewers and plenty of upload forms still don't accept AVIF. PNG is the universal fallback.

Squish decodes the AVIF and re-saves the exact pixels as a lossless PNG - transparency included, if the image has it. Drop in as many files as you like; each converts on arrival and Download all bundles them into a zip.

Common questions

Is the conversion lossless?
PNG itself is lossless, so you get a pixel-perfect copy of the decoded AVIF. Expect the PNG to be several times larger on disk - that's the price of universal compatibility. If size matters, convert to JPG or WebP instead using the format bar.
Is transparency preserved?
Yes - AVIF alpha channels carry straight over to PNG. (Convert to JPG and the transparency is flattened onto white, since JPG doesn't support it - Squish tells you when that happens.)
Can I go the other way - PNG to AVIF?
Yes. Drop in PNGs and pick AVIF as the output format - or WebP, which is nearly as small with even wider support. See the WebP compressor for that workflow.
What happens to my files?
Processed in memory, never stored. Nothing sticks around after your download.
