Convert to

The modern web font — ~30% smaller than WOFF, supported by every current browser.

Runs in your browser. Files are never uploaded — you can go offline after the page loads.

How to use the Font Converter

Drop TTF, OTF, WOFF or WOFF2 files.
Choose the target: WOFF2 for the web, WOFF for legacy support, TTF/OTF for installing.
Download each converted font, or everything as a ZIP.

Easy to use

Drop files, pick options, download. Whole folders at once, no signup, no daily limit.

Best quality

The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.

Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

Lossless by construction

TTF, OTF, WOFF and WOFF2 are containers around the same tables of glyph data. WOFF wraps them with zlib compression; WOFF2 with Brotli tuned for fonts (this tool runs Google's own woff2 encoder, compiled to WebAssembly). Converting changes the wrapper, never the letterforms — round-trip a font and the outlines are bit-identical.

Which format when

WOFF2 — the web format: smallest, supported by every browser since ~2016. Ship this.
TTF / OTF — for installing on Windows/macOS and for design tools. The converter detects whether outlines are TrueType or CFF and names the file correctly.
WOFF — only for supporting very old browsers alongside WOFF2.

One honest note: conversion is technical, licensing is not. Open-source fonts (OFL, Apache) convert and embed freely; commercial licences often sell web and desktop rights separately — check yours before shipping.

Frequently asked questions

Does converting a font lose quality?

No — these formats are containers around identical glyph data. WOFF/WOFF2 compress the tables (losslessly); converting back to TTF/OTF restores the original bytes of every table.

WOFF or WOFF2 for my website?

WOFF2 — about 30% smaller and supported by every browser released since 2016. Ship WOFF2 alone unless you must support museum-grade browsers, then add WOFF as a fallback.

Can I install a WOFF2 I downloaded?

Operating systems want TTF/OTF for installation. Convert the WOFF2 here and install the result — the tool detects whether the font’s outlines are TrueType or CFF and names the file .ttf or .otf accordingly.

Am I allowed to convert this font?

Format conversion is a technical act; the font’s licence still applies. Open-source fonts (OFL, Apache) allow it freely; commercial licences often restrict web embedding — check yours.

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
