Transparency
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.

AVIF can use lossy or lossless AV1 coding. Chroma subsampling, RGB↔YUV conversion and reduced bit depth can change source values even when the AV1 coding stage is lossless. Quality defaults to 55; adjust it in Advanced options. File size depends on the image and encoder.
