AVIF

AV1 Image File Format

Lolly opens and makes this format

The newest of the small-file image formats, built on the AV1 video codec: excellent compression, transparency, and real HDR support. Lolly can write an HDR AVIF for bright displays. It reads and writes wherever your browser supports it natively, and now carries a Content Credential over its native ISO-BMFF structure - so an AI-made or upscaled AVIF keeps its provenance instead of losing it on export.

Most tools like this are upload sites: your file goes to their server, and ads pay the bill. Lolly runs on your device, so your file stays with you.
