# Convert WOFF to OTF.

> Unwrap WOFF web fonts back to desktop OTF — in-browser.

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**.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop TTF, OTF, WOFF, WOFF2 or EOT files anywhere on the page — or click to browse.
2. Pick the output format — the font tables are repackaged losslessly, never re-drawn.
3. 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](https://compress-pro.com/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.
