GRAY to XPM Converter
Processing entirely on your device — large files may take a moment.
GRAY is the single-channel spelling of raw grayscale dumps — the same unformatted luminance bytes the GRAYA variant adds alpha to. Convert PNG or SVG output to XPM to feed icon themes and legacy toolkits.
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 GRAY format
The Grayscale + Alpha (raw) coder of the ImageMagick set — the raw-pixels 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
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)
Why convert GRAY to XPM?
Think of it as moving your file to the container that fits the job. Niche format — few modern readers XPM works differently: Plain text — diffs and greps If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this GRAY to XPM 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 GRAY to XPM?
No — XPM is a lossless format, so every pixel of the converted image matches your original GRAY file. You can also adjust the quality/size balance before converting when the target format supports compression.
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 GRAY files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to XPM?
Transparency is kept whenever XPM 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.
