Convert PPM files to PSD free in your browser — no signup, no install, and the file is never uploaded to a server. PSD keeps full quality with no further loss.
Add your PPM file
Drag the PPM file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm PSD as the output
PSD is already selected as the output format on this page. You can set the output width and height. Quality stays untouched because this format is lossless.
Run the conversion
Press the convert button. A single image is usually done before you finish reading this sentence.
Download the PSD file
When it finishes, download the PSD file. Converting multiple files gives you the option to download them together as a ZIP.
An extremely simple format consisting of a header followed by raw RGB values. It applies no compression so files are large, but its simplicity makes it popular in research and teaching.

No. The conversion runs entirely inside your browser using WebAssembly, so the PPM file never leaves your device. That is also why it works without an internet connection once the page has loaded.
It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
