XPM to DDS Converter
Processing entirely on your device — large files may take a moment.
X11 Pixmap and DirectDraw Surface exist for different jobs: XPM (X11 Pixmap) is an image written as C source code — plain ASCII text that compilers and editors ingest directly, the classic icon format of Linux desktops and legacy X11 apps. Convert a PNG or JPG into a DDS texture for game-engine imports, or back to PNG for inspection.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the XPM format
XPM (X11 Pixmap) is an image format that is literally C source code: pixels are listed as character-to-color mappings inside an ASCII array. Compilers, text editors and version control all treat it as plain text, which is why Linux desktop icons and legacy X11 application assets have used it for decades.
XPM is limited to 256 colors per image and stores no alpha beyond a designated transparent character, so it is a niche target: mainly icon themes, window-manager decorations and retro programming projects.
+Strengths
- ✓Plain text — diffs and greps
- ✓Compiles straight into C programs
- ✓Tiny for small flat icons
!Limitations
- −256 colors maximum
- −Poor alpha (one transparent color)
About the DDS format
DDS is the DirectDraw Surface texture format of DirectX game pipelines. This converter writes the uncompressed 32-bit BGRA variant — the universal fallback every engine's importer accepts before any compressed codec.
Mipmaps and block compression (BC1-7) are not written; the file is a flat full-resolution BGRA image with a classic DX header.
+Strengths
- ✓Universal engine-import fallback
- ✓Lossless, full alpha channel
- ✓No codec negotiation needed
!Limitations
- −No mipmap chain written
- −Uncompressed = large files
- −BC compressed variants not written
Why convert XPM to DDS?
Converting makes sense where the strengths of DDS meet what XPM cannot give you. Universal engine-import fallback Meanwhile 256 colors maximum One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this XPM to DDS converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting XPM to DDS?
No — DDS is a lossless format, so every pixel of the converted image matches your original XPM file. You can also adjust the quality/size balance before converting when the target format supports compression.
Will transparent areas survive the conversion to DDS?
Transparency is kept whenever DDS actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your XPM files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
