HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload your OTF fonts
Drag in .otf files from a type foundry, a font download or your design system.
02
Convert to WOFF2
Start the conversion. The font is packed with WOFF2's Brotli compression, then unpacked again and checked against the original.
03
Download the WOFF2
Download each WOFF2, or a whole family as one ZIP, and reference it with @font-face.
OTF
OTF is the OpenType font format, usually carrying PostScript-style (CFF) outlines and advanced typographic features.
WOFF2
WOFF2 is the compressed web font format browsers load fastest, about 30% smaller than the original WOFF.
FILE FORMATS
SOURCE
OpenType was created by Microsoft and Adobe in 1996 as a successor to TrueType and Type 1. An .otf file usually holds CFF outlines with cubic curves, preferred by type designers, plus OpenType features such as ligatures, small caps and alternates. Windows, macOS and design apps install it like any other font.
TARGET
The W3C published WOFF 2.0 in 2018. It wraps a TrueType or OpenType font with Brotli compression and font-specific transforms, typically making it 30% smaller than WOFF and far smaller than TTF. All current browsers load it, which is why Google Fonts and font services deliver WOFF2. Desktop systems can't install it directly.

USE CASES
When a desktop font needs to load quickly on the web.
Self-host a font on your website
WOFF2 is the smallest format browsers load, so pages render text sooner.
Cut page weight for Core Web Vitals
Smaller font files help Largest Contentful Paint on text-heavy pages.
Ship a brand font in a web app
Package your licensed brand typeface for a React, Vue or Svelte app.
Replace TTF or OTF links in CSS
Browsers download WOFF2 faster than raw OpenType files.
Add a variable font to a site
Variable CFF2 fonts keep their axes, so one file covers every weight.
Prepare fonts for an email builder
Some email and landing page tools take WOFF2 uploads.
Build a design system package
Distribute web fonts alongside your components.
Host fonts for a WordPress theme
Upload WOFF2 files for a theme's custom fonts.
Stop relying on a third-party font CDN
Self-hosting removes an external request and a privacy concern.
Convert a whole family at once
Pack every weight and style in one batch.
SUPPORTED FILES
OpenType fonts with CFF or CFF2 outlines are supported.
Regular, bold, italic and every other style.
CFF2 variable fonts keep their axes, such as weight and optical size.
Chinese, Japanese and Korean fonts with tens of thousands of glyphs.
Upload every style and download the WOFF2 files as a ZIP.
TTF files can be packed as WOFF2 as well; use the TTF converters for those.
Check your font license allows web embedding before publishing a converted font.
TROUBLESHOOTING
Most problems come from CSS or server setup, not the font file.
01
Check the @font-face src path and that format('woff2') is set. A wrong path shows a 404 in the browser's network tab.
02
Fonts loaded from another domain need a CORS header (Access-Control-Allow-Origin) on the server.
03
Serve .woff2 with the font/woff2 MIME type so browsers and CDNs cache it properly.
04
WOFF2 is a web format. Install the OTF on desktops.
05
Add font-display: swap to @font-face and preload the main weight.
06
Open the WOFF2 in a font inspector to confirm the family name matches your CSS.
