How do I convert a WOFF file to AFM using LetsConvert?

Upload your WOFF file to the converter, click Convert, and download the resulting .afm file. The tool parses the font's glyf and hmtx tables to generate an AFM-compatible metrics document, including character widths, kerning pairs, and bounding boxes. No installation or technical setup is required.

What is the difference between WOFF and AFM, and why would I convert WOFF to AFM?

WOFF is a compressed web font format that contains complete TrueType or OpenType outlines, intended for rendering text in browsers. AFM (Adobe Font Metrics) is a plain-text metadata file describing glyph names, widths, and kerning—used by typesetting systems like TeX, Adobe InDesign, and PostScript workflows. Converting WOFF to AFM lets you reuse metric data from a webfont in print or desktop layout software without needing the original font editor, but the outlines themselves are not carried over.

Does the WOFF-to-AFM conversion preserve kerning and glyph bounding boxes?

Yes. The conversion reads the font's 'hmtx' and 'kern' tables (or 'GPOS' for OpenType kerning) and writes them into the AFM format. Glyph bounding boxes are calculated from the 'glyf' or 'CFF' table if present. However, because AFM stores metrics only, color data, hinting instructions, and outline shapes are not included in the output file. The resulting AFM is a plain-text, human-readable representation of the font's metrics.
