What happens to your file
JPG cannot store transparency, so any RGBA, LA, or palette image is composited onto a solid white background first and then saved as RGB.
Settings this conversion runs with
| Engine | Pillow (Python Imaging Library) |
|---|---|
| Colour mode | RGB |
| Alpha channel | Flattened onto white |
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 J2C to JPG keeps the original pixel dimensions.
