RAS to DCX Converter
Processing entirely on your device — large files may take a moment.
Sun Raster and Multi-page PCX exist for different jobs: RAS is the Sun Raster image format of old Solaris workstations — a minimal header plus raw pixels, still common in legacy UNIX image archives. Convert images to DCX for legacy fax/document archives.
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.

About the RAS format
The Sun Raster coder of the ImageMagick set — the unix-archive format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing

Frequently asked questions
Is this RAS to DCX 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 RAS to DCX?
No — DCX is a lossless format, so every pixel of the converted image matches your original RAS file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several RAS files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
Will transparent areas survive the conversion to DCX?
Transparency is kept whenever DCX 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.
