Free TTF to WOFF2 Converter

What is a TTF to WOFF2 converter?

A TTF to WOFF2 converter compresses a desktop font into WOFF2, the web font format, so your pages load faster.

WOFF2 is a W3C standard. It compresses a font's tables with Brotli, after rearranging the outlines so they compress better.

How much smaller

Six open fonts, converted on September 30, 2026:

A variable font holds every weight in one file. As a WOFF2, one Lora file at 83 KB covers every weight from 400 to 700.

Every browser

caniuse counts WOFF2 in 97% of browsers in use, from Chrome 36, Firefox 39 and Safari 12 on.

So most sites need only the WOFF2. Add a WOFF only if your visitors use very old browsers.

What comes through

A font file is a wrapper around tables: the letters' outlines, the spacing between pairs (kerning), ligatures, a variable font's axes, and hinting for small sizes.

This converter only changes the wrapper, so every table comes back. I checked it table by table on six fonts with fontTools, the standard font toolkit:

• WOFF – every table came back byte for byte.
• WOFF2 – every letter and every table, but the digital signature (DSIG), which the WOFF2 standard drops, as every WOFF2 tool does.

Nothing is redrawn, so the letters look exactly as their designer made them.

Use it on your site

When you convert to WOFF2 or WOFF, the converter writes the @font-face rule for you: the font's family, its weight, its style, and font-display: swap, so text shows while the font loads.

A variable font gets its full weight range, like 400 700 for Lora, so one file covers every weight. Copy the rule into your CSS and put the font file next to it.

Compared with CloudConvert

I converted the same six fonts to WOFF2 with CloudConvert on September 30, 2026:

For TrueType fonts, CloudConvert uses the same WOFF2 engine as this converter, Google's. For OpenType fonts it switched to another program, which redrew the letters' curves.

The redrawn font also lost the names of its stylistic sets, like Slashed zero and Capital figures. This converter keeps the original curves and every name.

Check the license first

A font is software, and its license says where you can use it. Open fonts like Google Fonts' allow websites, apps and print.

Many fonts you buy license desktop use and web use separately. The converter shows each font's own license line, with its link, so you can check before you publish.

Nothing is uploaded

The converter runs in your browser, so a font you paid for never leaves your computer. There's no size limit but your computer's memory.

The first WOFF2 conversion downloads the engine, about 1 MB. After that it starts at once.

Who is the TTF to WOFF2 converter for?

It's for anyone putting a font on a website:

• DESIGN.md generator – designers setting up a site's type
• Website to HTML converter – developers rebuilding a page with its fonts
• Compress image – anyone making a site load faster
• SEO checker – site owners checking a page's speed and setup

Agencies use it to hand a client's typeface to their developers.
