How do I convert a WOFF file to PFM using the LetsConvert tool?

Upload your WOFF file to the converter, select PFM as the output format, and click 'Convert'. The tool will decompress the WOFF font, extract its outline and metric data, and generate a PFM (Printer Font Metrics) file containing character widths, kerning pairs, and bounding box information. Download the resulting PFM file and place it alongside your .PFB file for use in legacy PostScript workflows.

Why would I need to convert WOFF to PFM?

WOFF is a compressed web-font format used primarily in browsers, while PFM is a companion metrics file for Type 1 PostScript fonts used in desktop publishing and legacy printing environments. Converting WOFF to PFM allows you to reuse font metrics from open-source web fonts in professional print workflows, ensuring accurate line breaks and kerning when using software that relies on PFM/PFB pairs.

Does converting from WOFF to PFM preserve kerning and character widths?

Yes. The converter reads the glyf/loca tables (for TrueType-based WOFF) or CFF table (for OpenType-based WOFF) to extract the exact advance widths, side bearings, and kerning pairs. Since PFM is a metrics-only file, the outline data is not stored in the PFM; it must be supplied via a separate .PFB file. The conversion preserves all numeric metrics, including Unicode character mappings and GPOS kerning data, but discards embedding restrictions and WOFF-specific metadata.
