DCX 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 DCX format, this page is the shortcut: DCX is a multi-page container of PCX images — the fax-document format of ZSoft-era DOS software.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the DCX format
The Multi-page PCX coder of the ImageMagick set — the fax-archive format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing
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
Why convert DCX to PFM?
Think of it as moving your file to the container that fits the job. Niche format — few modern readers PFM works differently: Full floating-point precision If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this DCX 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 DCX to PFM?
No — PFM is a lossless format, so every pixel of the converted image matches your original DCX file. You can also adjust the quality/size balance before converting when the target format supports compression.
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 DCX files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Can I convert several DCX 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.
