- When you need it for photos
- To open your files in apps that prefer PGM

What happens to your file
The PNG is decoded into memory and written back out as PGM. Where Pillow's writer rejects the image's colour mode, the converter falls back to ImageMagick rather than failing the job.
Settings this conversion runs with
| Engine | Pillow (Python Imaging Library) |
|---|---|
| Path | Pillow decode → encode |
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 PGM keeps the original pixel dimensions.
