How to convert PNG to PPM
- Add your .PNG file - drop it in the box above or click to browse.
- Convert it to .PPM in a few seconds.
- Download your new .PPM file.
What to expect
- Pixel colour is preserved exactly - PPM is uncompressed RGB, so there is no quality loss, only a large file.
- PNG transparency (the alpha channel) is not supported by PPM and is discarded.
- Files are large because there is no compression; choose the binary (P6) form over ASCII (P3) to keep size down.
Frequently asked questions
Is PNG to PPM lossless?
Yes for the pixel data - PPM stores full RGB colour uncompressed, so the visible image is preserved exactly. The trade-off is file size rather than quality, since nothing is re-encoded lossily.
Why convert a PNG to PPM?
PPM is a plain, fully-documented uncompressed RGB bitmap from the Netpbm family, convenient for image-processing tools and scripts that want raw pixel data without dealing with PNG's compression.
What software opens a PPM file?
The free GIMP, IrfanView, and XnView MP open PPM on any platform, and the Netpbm utilities handle it on the command line. For general sharing, convert to PNG or JPG since PPM is rarely supported by everyday apps.
Why is the PPM so much bigger than the PNG?
PPM stores every pixel as raw RGB with no compression at all, while PNG compresses losslessly. That makes PPM files large; the binary P6 variant is much more compact than the ASCII P3 variant.
