Convert fonts between TTF, OTF, WOFF and WOFF2 — right in your browser. Nothing is uploaded.
About Font Tools
These font tools convert between the desktop formats (TTF, OTF) and the web formats (WOFF, WOFF2) — the exact step you need to use a font in a website's @font-face, or to install a web font on your computer. Everything runs in your browser: WOFF is handled with the browser's own compression, and WOFF2 uses Google's official woff2 engine compiled to WebAssembly, run in a background worker so the page never freezes. Your font is never uploaded — private, free, no sign-up.
Use the font converter to pick any output format, or a dedicated page like TTF to WOFF2 for a specific conversion. These are container conversions: the glyph outlines are preserved exactly, only the wrapper and compression change.
Frequently asked questions
Are my fonts uploaded?
No. The conversion runs entirely in your browser — WOFF2 via a WebAssembly engine in a worker, WOFF via the browser's compression. Your font never leaves your device.
Which formats are supported?
Input and output can be any of TTF, OTF, WOFF and WOFF2. WOFF2 is the smallest and best for modern websites; WOFF has the widest browser support.
Does converting change the font's look?
No. These are container/compression conversions — the glyph outlines and metrics are preserved exactly. Only the file wrapper and size change.
Can it convert TTF to OTF (or vice-versa)?
This tool focuses on web-font conversions (TTF/OTF ⇄ WOFF/WOFF2). A true TTF↔OTF outline change is a different, specialised job.
