PFM to TIFF Converter
Processing entirely on your device — large files may take a moment.
PFM (Portable Float Map) stores pixels as raw 32-bit floats — the lossless hand-off format for HDR pipelines, radiance research and render passes, riding the same family spirit as PBM/PGM/PPM. Convert to TIFF when submitting scans or print-ready artwork where maximum fidelity is required.
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 PFM compares to TIFF
| PFM | TIFF | |
|---|---|---|
| Compression | None (raw floats) | Lossless (LZW/ZIP) or none |
| Transparency | Not supported | Supported (alpha channel) |
| Animation | Not supported | Not supported |
| Metadata | Minimal header only | Rich tag system (EXIF, GeoTIFF) |
| Best for | HDR interchange, render passes | Print, scanning, archival |

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
About the TIFF format
TIFF, introduced by Aldus in 1986 and maintained by Adobe since, is the workhorse of the scanning, printing and archiving industries. It is a tag-based container: baseline RGB, CMYK, grayscale and indexed color, compressed with lossless LZW or ZIP (or not at all), with 8- or 16-bit depth and even multiple pages in a single file. A scanned contract or a print-ready magazine page lives in TIFF.
Its historical weakness is dialect fragmentation: the tag system is so flexible that exotic TIFFs — GeoTIFFs, fax TIFFs, certain 16-bit CMYK variants — still trip up careless readers. Files are huge, and no browser displays TIFF natively, so it never escaped its professional niches.
+Strengths
- ✓Lossless with up to 16-bit-per-channel depth
- ✓Multipage support — one file, many scans
- ✓CMYK and print-industry color handling
- ✓Rich, extensible tag metadata for archiving
!Limitations
- −Very large files, even compressed
- −Dialect fragmentation trips up simple readers
- −No native browser display
Why convert PFM to TIFF?
Converting makes sense where the strengths of TIFF meet what PFM cannot give you. Lossless with up to 16-bit-per-channel depth Meanwhile Enormous files (16 bytes per pixel) One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this PFM to TIFF 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 PFM to TIFF?
No — TIFF is a lossless format, so every pixel of the converted image matches your original PFM 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 PFM 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 PFM 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.
