What is a PFM file?
A .PFM file often functions as a Portable FloatMap image file. This format stores high dynamic range (HDR) image data. The Netpbm project and developers use this format for complex HDR image processing.
Alternatively, a .PFM file can be a Printer Font Metrics File created by Adobe Systems. These files store font spacing and kerning data for Adobe Type 1 fonts. Software like Fontographer uses these files to generate and edit typefaces. Finally, .PFM files can also store CAD models for Autodesk PowerShape.
How to open PFM files?
Since a .PFM file has multiple possible meanings, you must identify the correct format before opening it. If it is an image, you can open it with Adobe Photoshop or command-line tools from pfstools. If it is a Printer Font Metrics File, you need the corresponding .PFB file to install the font on your system.
Software and tools
For image files, use Adobe Photoshop or GIMP. For font metrics, use FontLab or the legacy Fontographer. For CAD files, you need Autodesk PowerShape. To change the file format, we recommend file conversion to sensible target formats like .JPG, .PNG, or .TTF on convert.guru.
Best practices and troubleshooting
Because .PFM extensions are shared across different domains, opening them can be difficult. viewer.online/pfm analyzes .PFM files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. This helps you figure out if you have an HDR image, a font file, or a 3D model.
Summary
viewer.online/pfm directly opens and previews .PFM files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
