PALM to PFM Converter
Processing entirely on your device — large files may take a moment.
Palm Pilot Bitmap and Portable Float Map exist for different jobs: PALM is the Palm Pilot bitmap format — 1/2/4/8-bit paletted images from the original PDA ecosystem. Convert PFM to PNG or JPG to get a viewable tone-mapped preview of float data.
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.

About the PALM format
The Palm Pilot Bitmap coder of the ImageMagick set — the retro-pda 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 PALM to PFM?
Converting makes sense where the strengths of PFM meet what PALM cannot give you. Full floating-point precision Meanwhile Niche format — few modern readers One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this PALM 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 PALM to PFM?
No — PFM is a lossless format, so every pixel of the converted image matches your original PALM file. You can also adjust the quality/size balance before converting when the target format supports compression.
Will transparent areas survive the conversion to PFM?
Transparency is kept whenever PFM 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.
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 PALM files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
