Convert AVIF to JPG
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.
The classic photo format: smaller files by discarding detail your eye barely notices, which makes it ideal for photographs but poor for crisp graphics or text. It's always opaque (no transparency). Lolly tags it sRGB, can write an HDR version for bright displays, and embeds provenance and Content Credentials.
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.

What Lolly supports
- Pixel raster image
- Compressed (lossy)
- HDR bright colour
- Content Credentials (C2PA)
What carries over: EXIF, XMP - The converter moves the description, author, copyright and capture date into the new file. Location stays behind unless you turn it on, and a Content Credential cannot be copied: it is bound to the original bytes.
Content Credentials survive this format
