PCX to DDS Converter
Processing entirely on your device — large files may take a moment.
ZSoft Paintbrush PCX and DirectDraw Surface exist for different jobs: PCX was THE DOS-era image format: ZSoft Paintbrush's RLE-compressed raster that every 1990s game, scanner and clipart CD shipped in. Simple enough that its spec fits on one page. Convert a PNG or JPG into a DDS texture for game-engine imports, or back to PNG for inspection.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How PCX compares to DDS
| PCX | DDS | |
|---|---|---|
| Structure | 128B header + RLE rows + 769B palette | DX header + BGRA8 pixels |
| Compatibility | DOS era, GIMP, ImageMagick | Unreal/Unity/Godot importers |
| Best for | Retro game and clipart archives | Game texture import |

About the PCX format
PCX was the image format of the DOS decade: ZSoft Paintbrush's run-length-encoded raster that every scanner, game and clipart CD adopted because it was published, simple and fast on 286 hardware. The header is a fixed 128 bytes, the palette hides in the final 769, and the whole file can be decoded by one while-loop.
Retro gaming archives and 90s clipart collections are full of PCX files. Converting them to PNG or JPG finally makes them viewable — the pixels were always fine, the container was just ancient.
+ Strengths
- ✓Decoded by a single RLE loop — no dependencies
- ✓Ubiquitous in DOS-era archives
- ✓Supports paletted and 24-bit variants
! Limitations
- −Effectively dead since Windows 95
- −Rows padded — some files have alignment quirks
- −256-color ceiling for most real-world files
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 PCX to DDS?
Converting makes sense where the strengths of DDS meet what PCX cannot give you. Universal engine-import fallback Meanwhile Effectively dead since Windows 95 One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this PCX 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 PCX to DDS?
No — DDS is a lossless format, so every pixel of the converted image matches your original PCX 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 PCX files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
