XPM to SVGZ Converter
Processing entirely on your device — large files may take a moment.
Convert SVGZ exactly like SVG — the converter inflates it first — or gzip an SVG back into SVGZ for shipping. If your files are still in XPM format, this page is the shortcut: 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.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

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 SVGZ format
SVGZ is what every SVG is on a well-configured server: the same XML vector content run through gzip. XML compresses spectacularly, so an SVGZ is typically 70-80% smaller than the SVG it came from — which is why Apache and nginx can serve it transparently with a Content-Encoding header.
Converting SVGZ to PNG or JPG simply inflates it first — the vector content is byte-identical to its SVG parent. The other direction (vectorize a raster, then gzip) produces a deploy-ready compressed asset.
+Strengths
- ✓70-80% smaller than the same SVG
- ✓Transparent to browsers via Content-Encoding
- ✓Full SVG vector fidelity
!Limitations
- −Some tools refuse the double extension
- −Needs gunzip before hand-editing
- −MIME confusion on misconfigured servers
Why convert XPM to SVGZ?
Converting makes sense where the strengths of SVGZ meet what XPM cannot give you. 70-80% smaller than the same SVG 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 SVGZ 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 SVGZ?
No — SVGZ 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 SVGZ?
Transparency is kept whenever SVGZ 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.
