How to convert truetype or opentype to a legacy svg font
- Step 1Drop your TTF or OTF file — The tool parses the font with opentype.js, extracts the glyph set, and walks each glyph's path data using the same getPath() method browsers use internally.
- Step 2SVG document is built — An <svg> root with <font> + <font-face> + N <glyph> children. Each glyph carries its unicode, glyph-name (when available), advance width, and full path d-attribute.
- Step 3Download or paste-embed — The output is plain text, openable in any text editor. PDF libraries that consume SVG Fonts can embed the result directly into PDF generation pipelines.
Frequently asked questions
Is SVG Font ever the right format for the web?+
Almost never in 2026. Browsers dropped SVG Font rendering between 2017 and 2019. The only browser that ever supported it well was Safari, and that support is gone too. For web delivery, always choose WOFF2.
Why does the file expand so much?+
SVG Fonts use XML — every glyph carries its Unicode label, glyph name, and full path data as text. A 50 KB TTF becomes a 200–400 KB SVG Font. The format has no compression beyond gzip on the wire.
Will the SVG Font preserve kerning?+
SVG Fonts have a <hkern> element for pairs, but most SVG Font consumers ignore it. The JAD output omits hkern for simplicity — if your downstream tool needs it, the kerning data is in the original TTF and can be added in post-processing.
Privacy first
Every JAD Font tool runs entirely in your browser using opentype.js and the wawoff2 WASM Brotli encoder. Your fonts never leave your device — verified by zero outbound network requests during processing.
