Convert OTF to WOFF2
10 / 10OpenType .otf in, compressed WOFF2 out — with ligatures, alternates and small caps intact and @font-face CSS generated. Batch up to 10 files.
OTF vs TTF: what changes for the web
OTF usually means OpenType with PostScript (CFF) outlines — the format most type foundries ship for desktop. WOFF2 accepts CFF outlines as they are, so converting an OTF does not flatten curves to TrueType or touch the design. Advanced OpenType features (contextual alternates, discretionary ligatures, stylistic sets, fractions) all survive; the browser applies them through font-feature-settings or font-variant.
Check the license first
Most commercial OTFs are licensed for desktop use only; embedding them on a website requires a web license from the foundry. Open-source families (OFL, Apache) can be converted and self-hosted freely — the Fonts Library labels each family’s license so you can tell at a glance.
Ready-to-use output
You get one WOFF2 per uploaded file, an @font-face stylesheet with correct weights and styles, and an HTML snippet showing the font in use. Everything is processed on our servers and deleted within an hour.
OTF to WOFF2 — questions
Yes. GSUB/GPOS tables are copied unchanged, so ligatures, alternates and kerning behave exactly as in the desktop font.
CFF outlines are already compact, so the gain is smaller than for TTF — usually 20–40%. It is still the smallest web format available.
Yes — tick TTF in the output formats. Note that CFF-to-TrueType conversion re-approximates curves, so it is not byte-identical.

How the Font Converter Works
Upload your desktop fonts and get web-ready files in seconds. Our converter handles all the heavy lifting — subsetting, compression, and format generation — so your fonts load fast on every browser.
Supported Formats
Convert between TrueType (TTF), OpenType (OTF), WOFF, and WOFF2. WOFF2 offers the best compression for the web — up to 30% smaller than WOFF — and is supported by all modern browsers.
Batch Processing
Upload up to 10 font files at once and convert them all in a single run. Each file is processed server-side and packaged into a ready-to-use ZIP with your chosen formats.
Generated CSS & Preview
The converter generates @font-face CSS declarations with the correct font-display strategy. An HTML preview page is included so you can verify rendering before deploying.
Privacy First
Uploaded files are processed on the server and automatically deleted after conversion. Nothing is stored permanently — your fonts stay yours.
Frequently Asked Questions
WOFF2 uses Brotli compression, which produces files about 30% smaller than WOFF (which uses zlib). Both are web font formats, but WOFF2 is recommended for modern browsers due to better compression and faster loading. WOFF remains useful as a fallback for older browsers.
Yes. The converter handles direct conversion from any supported input format (TTF, OTF, WOFF, WOFF2) to any output format. No intermediate steps are needed — just upload and select your target format.
The font-display CSS descriptor controls how a font is displayed while it is loading. The "swap" option (recommended) shows a fallback font immediately, then swaps to the web font once loaded. This avoids invisible text during page load and improves Core Web Vitals.
Each individual file can be up to 10 MB, and you can upload up to 10 files per batch. This covers virtually all desktop and web font files, including large variable fonts.
For most modern websites, WOFF2 alone is sufficient — it is supported by over 97% of browsers globally. Add WOFF as a fallback if you need to support older browsers. TTF and EOT are rarely needed today unless targeting very old systems.
