XPM to WIM Converter
Processing entirely on your device — large files may take a moment.
X11 Pixmap and Windows Imaging Format 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. Extracting WIM to ZIP exposes the files inside Windows images without deployment tools.
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 WIM format
WIM (Windows Imaging Format) is how Microsoft ships Windows itself: the install media and deployment images are WIM files, holding a complete filesystem snapshot with single-instancing (identical files stored once). It is Windows' answer to tar — file-based rather than sector-based.
Opening one without deployment tooling (DISM, 7-Zip on Windows) is awkward. Extracting WIM to ZIP exposes the files inside — drivers, scripts, provisioned apps — on any system, no Windows required.
+Strengths
- ✓Windows' native image format
- ✓Single-instancing deduplicates identical files
!Limitations
- −Opaque without Microsoft tooling
- −Files inside may be Windows-locked
Why convert XPM to WIM?
Converting makes sense where the strengths of WIM meet what XPM cannot give you. Windows' native image format 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 WIM 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 WIM?
No — WIM 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.
Can I convert several XPM 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 WIM?
Transparency is kept whenever WIM 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.
