## Good to know

- PGM doesn't support transparency, so transparent areas are filled with white.
- PNG files are typically used for screenshots, logos, UI assets and any graphic that needs sharp edges or a transparent background, while PGM is best for grayscale image processing.
- This conversion runs on ImageMagick, running locally in your browser — nothing is uploaded and it works even on slow connections.
