Will the font look any different after converting to WOFF2?

No. WOFF2 is a compression wrapper around the exact same glyph outlines, hinting, and metrics the source TTF/OTF contains — nothing about how the font renders changes, only the file size and format.

How much smaller will my font file get?

It varies by font, but 40-60% smaller than the original TTF/OTF is typical, since Brotli compression combined with WOFF2’s table transform is significantly more efficient than an uncompressed desktop font file.

Do I still need the original TTF for anything after converting?

Keep it if you ever need to install the font locally on a desktop (WOFF2 is a web-only format, not something operating systems install directly), or if you need to convert to a different format later.

Can I convert an OTF file the same way as TTF?

Yes, both TTF and OTF are SFNT-based formats and the WOFF2 encoder handles either one identically — just upload your .otf file and it works the same way.

Do all browsers support WOFF2?

Yes, every modern browser (Chrome, Firefox, Safari, Edge) has supported WOFF2 since roughly 2018. For legacy browser support you’d additionally need a WOFF1 fallback, which isn’t covered by this tool.

Is my font file uploaded anywhere during conversion?

No. The WebAssembly encoder runs entirely in your browser tab — your font file never leaves your device.

Will this work with variable fonts?

Variable font tables are part of the standard SFNT structure, so they’re preserved through the WOFF2 conversion along with everything else in the font.

Can I use the converted WOFF2 font for commercial projects?

The conversion itself doesn’t change your font’s license — whatever usage rights came with your original TTF/OTF file still apply to the WOFF2 version.

Why is WOFF2 better than just gzipping a TTF file?

WOFF2’s font-specific table transform reorganizes glyph data in a way generic gzip compression doesn’t understand, so WOFF2 consistently beats gzip-compressed TTF by a meaningful margin even though both use similar underlying compression math.

Does this tool change my original TTF file?

No. It only reads the source file to generate a new, separate WOFF2 file — your original font file is left completely untouched.

What is TTF to WOFF2?

WOFF2 is the current web standard font format — a font file compressed with Brotli (the same algorithm behind modern HTTP compression) using an encoder specifically tuned for font data's internal structure, typically producing files 30-50% smaller than the equivalent WOFF1 and significantly smaller than a raw TTF or OTF. Every major browser has supported WOFF2 since around 2018, and today it's the format every serious web performance guide recommends for self-hosted fonts.

This tool uses Google's own reference WOFF2 encoder, compiled to WebAssembly, running entirely in your browser tab. It takes the exact same SFNT font data a TTF or OTF file contains — glyph outlines, hinting instructions, metrics tables — and re-encodes it with WOFF2's font-specific transform (which reorganizes glyph and location tables for better compression) followed by Brotli compression. The visual output of the font is identical; only the file's byte size and wrapper format change.

For a typical desktop-distributed TTF font, expect a 40-60% size reduction after WOFF2 conversion, which translates directly into faster page loads for any site serving custom fonts — font files are render-blocking resources in most setups, so shaving even 50KB off a webfont can measurably improve how quickly text becomes visible.

Need to go the other direction and get a usable desktop font back out of a WOFF2? Use WOFF2 to TTF.

How It Works

The uploaded TTF/OTF file's raw SFNT byte data is passed directly to Google's reference WOFF2 encoder (compiled to WebAssembly via Emscripten), which applies the WOFF2-specific table transform — reorganizing the glyf and loca tables into a more compressible layout — then compresses the result with Brotli. The output is a complete, spec-compliant .woff2 file ready to reference in a CSS @font-face rule.

How to Use

Upload your font file

Drop a .ttf or .otf file onto the upload area, or click to browse for it.

Click Convert to WOFF2

Google’s reference encoder compresses your font using Brotli and the WOFF2 table transform.

Download the WOFF2 file

Save the result — it keeps your original filename with a .woff2 extension.

Reference it in CSS

Add the file to your @font-face rule’s src with format("woff2") to use it on the web.
