PCX to PFM Converter
Processing entirely on your device — large files may take a moment.
Convert PFM to PNG or JPG to get a viewable tone-mapped preview of float data. If your files are still in PCX format, this page is the shortcut: PCX was THE DOS-era image format: ZSoft Paintbrush's RLE-compressed raster that every 1990s game, scanner and clipart CD shipped in. Simple enough that its spec fits on one page.
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 PCX format
PCX was the image format of the DOS decade: ZSoft Paintbrush's run-length-encoded raster that every scanner, game and clipart CD adopted because it was published, simple and fast on 286 hardware. The header is a fixed 128 bytes, the palette hides in the final 769, and the whole file can be decoded by one while-loop.
Retro gaming archives and 90s clipart collections are full of PCX files. Converting them to PNG or JPG finally makes them viewable — the pixels were always fine, the container was just ancient.
+Strengths
- ✓Decoded by a single RLE loop — no dependencies
- ✓Ubiquitous in DOS-era archives
- ✓Supports paletted and 24-bit variants
!Limitations
- −Effectively dead since Windows 95
- −Rows padded — some files have alignment quirks
- −256-color ceiling for most real-world files
About the PFM format
PFM (Portable Float Map) stores pixels as raw 32-bit floating-point values — no palette, no compression tricks, just the numbers. It belongs to the Netpbm family (PBM/PGM/PPM) and is the lingua franca for handing high-dynamic-range data between renderers, tone-mapping experiments and radiance research scripts.
Because the values are floats, a PFM can hold sunlight and candlelight in the same image without clipping. Viewers rarely open it directly: convert to PNG or JPG to get a tone-mapped preview of the same data.
+Strengths
- ✓Full floating-point precision
- ✓Dead-simple text/binary layout
- ✓Widely read by research tooling
!Limitations
- −Enormous files (16 bytes per pixel)
- −Almost no viewer support

Frequently asked questions
Is this PCX to PFM 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 PCX to PFM?
No — PFM is a lossless format, so every pixel of the converted image matches your original PCX file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several PCX 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 PCX files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
