About PFM files

The .PFM extension refers to two distinct file types that often cause compatibility headaches due to their specialized nature.

1. Portable FloatMap Image (Primary): This is a raw, uncompressed floating-point image format used to store High Dynamic Range (HDR) data, often in computer graphics and scientific visualization.

Constraints: Because PFM files store 32-bit floating-point values directly, they are exceptionally large compared to standard images. They are not supported by web browsers or standard photo viewers (like Windows Photos or macOS Preview). Sharing a PFM file typically results in the recipient being unable to open it.
Conversion Targets: To share or view these images on the web, convert them to PNG or JPG (note: this clamps the dynamic range). For professional editing while preserving HDR data, convert to EXR or TIFF.

2. Printer Font Metrics (Secondary): A legacy file created by Adobe Systems for PostScript Type 1 fonts. It contains binary data regarding character spacing and kerning but does not contain the actual glyph shapes (which reside in a companion PFB file).

Constraints: You cannot install a font using only a .PFM file; the set is incomplete without the PFB. Furthermore, Type 1 fonts are considered obsolete, with support dropped in modern versions of Adobe Photoshop and Microsoft Office.
Conversion Targets: To use these legacy fonts on modern systems, you must convert the Type 1 pair (.pfm + .pfb) into a single OTF (OpenType) or TTF (TrueType) file.
