Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
Unwrapping a WOFF returns the exact desktop font that was packaged into it. If that font has PostScript (CFF) outlines you get an .otf; if it is a TrueType font you get a .ttf — either way, byte-identical tables and a file you can install.
How it works
- Drop TTF, OTF, WOFF, WOFF2 or EOT files anywhere on the page — or click to browse.
- Pick the output format — the font tables are repackaged losslessly, never re-drawn.
- Convert, then download each font on its own or the whole batch as a ZIP.
What the extension really tells you
TTF and OTF are the same container structure inside; the extension just signals which outline flavor the font carries. This tool reads the actual tables and names the output accordingly — renaming a file by hand converts nothing.
| Extension | Outlines | Curve math | Typical origin |
|---|---|---|---|
| .ttf | TrueType (glyf) | Quadratic Béziers | System fonts, Google Fonts |
| .otf | PostScript (CFF) | Cubic Béziers | Foundry retail & Adobe faces |
Why the tool refuses to fake it
Converting between outline flavors is possible in a font editor but never free: quadratic-to-cubic approximates curves, cubic-to-quadratic adds points, and hand-tuned hinting dies either way. A converter that silently rewrites outlines hands you a subtly worse font wearing the extension you asked for. This one unwraps what is actually there instead — the same glyphs the site rendered, under an honest name. Need the web wrapper back afterwards? OTF to WOFF reverses the trip.
Frequently asked questions
Why did my file come out as .ttf?
Because the WOFF contained TrueType outlines — .otf is by convention the extension for PostScript (CFF) outlines. Converting between outline types would cost hinting and shape fidelity, so the tool never does it: same font, honest extension, and a note tells you when it happens.
Is the unwrapped font identical to the original?
Yes — WOFF stores each table zlib-compressed, and decompression returns the exact original bytes: outlines, kerning, OpenType features, hinting, everything.
Am I allowed to convert this font?
The wrapper changes, the license does not — and direction matters here: a font licensed for web embedding is not automatically licensed for desktop installation or further distribution. Unwrapping a font you own, or one under the OFL or Apache licenses, is fine; for anything else read the terms before installing. Nothing is uploaded either way — the file stays on your device.
Is it private?
Yes. The font is repackaged entirely in your browser — it is never uploaded, and the server does nothing but deliver this page. For licensed fonts that matters twice over: nothing is redistributed to any third party, and no copy lingers on a server afterwards. Want proof? Run one file through, switch your connection off, and run another — it still works.
