Browser canvas encoders vary. AVIF output is offered only when the browser can encode it. Not a lossless professional codec.
FAQ
- Are images uploaded?
- No. Compression runs locally.
- Why is AVIF unavailable?
- Some browsers can decode AVIF but not encode it. We report that instead of faking a file.
