What is a .PFM file?
Everything worth knowing about Printer Font Metrics File.
A PFM file is a Printer Font Metrics file, a small binary companion to a Type 1 PostScript font (.PFB) on Windows. It holds character widths, kerning, and spacing data that Windows needs to display the font correctly. To use it, open both the .PFM and .PFB files together in FontForge, or convert the pair to OTF/TTF for installation on modern Windows.

Frequently asked questions
Why does my .PFM file look dark or washed out elsewhere?
Most image viewers show HDR files without any exposure control, so they look too dark or clipped. Here you can set the exposure and tone curve yourself, or press Auto to center the average brightness on mid-gray.
What do the pixel values mean?
Hover the image to read the linear light values (1.0 = diffuse white) and how many stops brighter or darker than mid-gray each pixel is. Values above 1.0 are highlights a normal JPG can't hold.
What is false color?
A diagnostic view that paints each pixel by brightness in stops: blue for deep shadows, green around mid-gray, red and white for highlights. It's how cinematographers and lighting artists check exposure.
Is my .PFM file uploaded?
No. EXR, HDR and PFM files are decoded for you. The decoder is downloaded from a public CDN.
Can I save the HDR as HDR?
The export is the tone-mapped 8-bit image (PNG, JPG or WEBP) at your chosen exposure. Converting between HDR formats is coming soon.
