XPM to PNG24 Converter
Processing entirely on your device — large files may take a moment.
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 PNG24 images like any PNG — to JPG for photos, WebP for the web.
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.
How XPM compares to PNG24
| XPM | PNG24 | |
|---|---|---|
| Compression | None (ASCII text) | Lossless (DEFLATE) |
| Transparency | Single transparent color | Full alpha (8/16-bit) |
| Animation | Not supported | Only via APNG extension |
| Metadata | Not supported | tEXt chunks, ICC profile |
| Best for | Linux icons, X11 themes | Screenshots, logos, sharp graphics |

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 PNG24 format
PNG was created in 1996 as a free, open replacement for the patent-encumbered GIF, and it has been the reference lossless image format ever since. Pixels are compressed with the DEFLATE algorithm (the same one inside ZIP files), which reproduces the original image exactly — bit-for-bit — while supporting full 8-bit or 16-bit alpha transparency. Screenshots, logos, icons, charts and anything with text or sharp edges should live in PNG.
Because it never discards information, PNG files of photographs are several times larger than JPG — that is the price of perfection. Modern PNG encoders add filters per scanline that make screenshots and flat-color graphics compress surprisingly well. PNG also became the base of APNG, the animation extension that browsers play natively.
+Strengths
- ✓Truly lossless — every pixel survives exactly as it was
- ✓Full alpha transparency with smooth edges, not 1-bit masks
- ✓Open standard, unpatented, with excellent tooling everywhere
- ✓Ideal for text, line art and flat-color graphics — sharp edges stay sharp
!Limitations
- −Photographs become several times larger than JPG
- −Base format has no animation (that is the APNG extension)
- −16-bit or high-resolution PNGs can grow very heavy
Why convert XPM to PNG24?
There is a concrete reason this conversion exists: 256 colors maximum PNG24 sidesteps that — Truly lossless — every pixel survives exactly as it was If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this XPM to PNG24 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 PNG24?
No — PNG24 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 PNG24?
Transparency is kept whenever PNG24 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.
