What happens to your file
AVIF uses a modern video codec to compress a still image, which is why it reaches much smaller files than JPG at the same visual quality.
Settings this conversion runs with
| Engine | Pillow (Python Imaging Library) |
|---|---|
| Codec family | AV1 (AVIF) |
What changes
- Nothing in the picture is resampled unless you ask for it — resize, crop-to-aspect, and background removal are opt-in, so a plain PNG to AVIF keeps the original pixel dimensions.
