What happens to your file
PNG output is lossless, then run through a size optimizer: pngquant is used when it is available on the worker, with Pillow's own quantizer as the fallback. Drop the quality setting below 80 (or switch on Optimize) and the palette is reduced up front instead.
Settings this conversion runs with
| Engine | Pillow (Python Imaging Library) |
|---|---|
| Compression | Lossless |
| Optimizer | pngquant when available, Pillow quantize as fallback |
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 PPM to PNG keeps the original pixel dimensions.
