When should you convert PNG to SGI?
- When you need it for graphics
- When you need it for photos
- To open your files in apps that prefer SGI
- To share SGI files more easily
What happens to your file
The PNG is decoded into memory and written back out as SGI. 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 SGI keeps the original pixel dimensions.
