WOFF to AFM conversion is the process of extracting font metric data from a Web Open Font Format (WOFF or WOFF2) web-optimized font and converting it into an Adobe Font Metrics (AFM) file, which stores character widths, kerning and font metric information in a plain-text format. This conversion is useful when you need AFM metric files for desktop typesetting, PDF generation, or legacy workflows that require detailed font metric tables separate from the font outlines.

Drag your .WOFF file from your computer or use the browse function.
Confirm .afm as the selected destination format.
Click "Convert" and download your converted .AFM file once ready.
WOFF files use the MIME type 'font/woff' and are typically used for embedding fonts in web pages, supporting compression codecs like zlib. AFM files have the MIME type 'application/octet-stream' and contain plain text metrics data used by Adobe applications for precise font rendering and layout. Converting WOFF to AFM extracts font metrics to support desktop publishing workflows.
The AFM (.AFM) format is commonly used for other. Understanding its characteristics can be helpful when converting to or from other formats like WOFF.
While specific technical details aren't available here, AFM files generally serve the purpose of storing other effectively within their domain.
Easily convert your WOFF font files to AFM format online using our efficient and user-friendly converter. Designed to provide a seamless conversion experience, our tool ensures that your font files maintain integrity while transforming from WOFF to AFM.
WOFF is primarily a web font format optimized for efficient online delivery, while AFM is an Adobe font metric file used mainly for desktop and print applications. WOFF packages compressed font data, whereas AFM focuses on providing detailed font metric information. Choosing between them depends on whether the font is intended for web use or precise typographic control in print.
Keep individual WOFF files under 50–100 MB for fastest processing; very large web fonts may slow conversion or require more memory.
To preserve metric accuracy, use conversion tools that support WOFF2 and extract postscript or TrueType outlines; avoid tools that only approximate widths.
For batch conversions, group fonts with the same encoding and naming conventions to ensure AFM files are generated with consistent metrics and glyph names.
Note format limitation: WOFF is a font container with outlines and tables, while AFM contains only metrics (no glyph outlines, hinting, or OpenType features). You cannot reconstruct outlines from an AFM.
