What to know about DDS to BMP conversion
- BMP 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.
- BMP has no transparency, so transparent areas of the DDS are filled with white.
- BMP is best for pixel-exact images for legacy Windows software, and opens in Windows apps and most image editors.

DDS (DirectDraw Surface): An image format designed by Microsoft for storing textures and cubic environments for rendering engines.
BMP (Bitmap Image File): A classic uncompressed raster graphics format developed by Microsoft, preserving pixel-perfect quality.

Frequently asked questions
Is it safe to convert DDS to BMP 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.
