What to know about DDS to PNM conversion
- PNM is lossless: it stores the decoded image exactly, which usually makes files larger than the original DDS, but prevents further quality loss when you edit again.
- PNM has no transparency, so transparent areas of the DDS are filled with white.
- PNM is best for image processing pipelines and scientific code, and opens in GIMP, ImageMagick and Netpbm tools.

DDS (DirectDraw Surface): An image format designed by Microsoft for storing textures and cubic environments for rendering engines.
PNM (Netpbm Portable Anymap): The generic Netpbm format family (PBM, PGM, PPM) for simple uncompressed bitmaps, graymaps and pixmaps.

Frequently asked questions
Is it safe to convert DDS to PNM here?
Yes. Your files are processed entirely on your own device by WebAssembly code running in the browser. They are never uploaded, so nobody else can see them, and the converter keeps working even if your connection drops after the page loads.
Is there a file size limit?
There is no server-side limit. The only limit is the memory available to your browser, typically 1.5–4 GB on desktop computers.
Can I convert several DDS files at once?
Yes. Add as many files as you like; they are converted in parallel according to your device's CPU cores, and you can apply the same settings to all of them.
