PNG8 XBM
100% private — files never leave your device

PNG8 is PNG with an 8-bit indexed palette — at most 256 colors, the "GIF-quality" PNG that Fireworks era designers exported for tiny file sizes. Convert XBM icons to PNG for viewing, or emit XBM when embedded firmware/Unix code needs a compiled-in bitmap.

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.

How to convert PNG8 to XBM

  1. 1

    Drag & drop your PNG8 files onto the area above, or click to browse. You can add multiple files at once for batch conversion.

  2. 2

    Convert instantly

    Click "Convert to XBM". The conversion runs entirely inside your browser using WebAssembly — no upload, no queue, no waiting.

    Download each converted XBM file individually, or grab everything at once as a ZIP archive.

About the PNG8 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

About the XBM format

XBM is the most honest image format ever shipped: the "file" is a C source array of hex bytes, compiled straight into X11 applications as cursor and icon bitmaps. Rendered, it is 1-bit black and white — the ancestors of every pixel-art cursor you still use.

Because it compiles, XBM never died: firmware UIs, embedded icons and retro Unix tooling still want it. Converting a PNG down to XBM gives embeddable, compilable art; the other direction previews what the C array actually draws.

+ Strengths

  • ✓Compiles directly into C/C++ programs
  • ✓Zero-payload format — text only
  • ✓Still required by embedded and Unix tooling

! Limitations

  • −1-bit black & white only
  • −Human-hostile representation
  • −X11 bit order trips up hand-rolled decoders

Why convert PNG8 to XBM?

There is a concrete reason this conversion exists: Photographs become several times larger than JPG XBM sidesteps that — Compiles directly into C/C++ programs If that is your situation, the tool above settles it in seconds, entirely on your device.

Frequently asked questions

Is this PNG8 to XBM 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 PNG8 to XBM?

No — XBM is a lossless format, so every pixel of the converted image matches your original PNG8 file. You can also adjust the quality/size balance before converting when the target format supports compression.

Can I convert several PNG8 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.

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 PNG8 files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
