Reasons to switch from PSD to PNM
- One extension for the whole Netpbm family
- Uncompressed and simple
- Friendly to scripting
- Works with: GIMP, ImageMagick, Netpbm and OpenCV
What to expect from this conversion
- Both formats store the pixels without loss, so the picture stays identical. Only the file size and compatibility change.
- PNM has no transparency, so transparent areas are filled with a background colour. White by default, and you can choose another colour in the options.
- The flattened composite of your PSD is converted. Individual layers, masks and adjustment layers are not exported.
- Browsers do not display PNM files, so use it in editors, print workflows or development tools rather than on a web page.

Tips for the best result
- Use quality 80 to 90 for photos: it is visually close to the original at a much smaller size.
- Set a width if the image will be shown on a small screen, which also reduces the file size.
- Choose a background colour before converting transparent images to a format without transparency.
