WOFF2, Web Open Font Format 2
WOFF2 (Web Open Font Format 2) is the format every modern website should be shipping. It is a Brotli-compressed envelope around a TrueType or OpenType font that is roughly 30 percent smaller than the original WOFF, with zero rendering difference. Every browser released since 2016 supports WOFF2 natively, including Chrome, Firefox, Safari, Edge, and the major mobile browsers. If you serve web fonts in 2026, WOFF2 is the right answer.

When to use WOFF2
Google engineers Raph Levien and Roderick Sheeter designed WOFF2 in 2014, replacing WOFF's zlib compression with Brotli, Google's then-new compression algorithm tuned for the patterns found in OpenType data. Chrome shipped WOFF2 support in version 36 in mid-2014; Firefox followed in version 39 in 2015; Safari in version 10 in 2016. The W3C published WOFF2 as a Candidate Recommendation in 2016 and a full Recommendation in 2018. The size win was immediate and dramatic: typical font payloads dropped 25 to 50 percent overnight, and WOFF2 has been the recommended web font format ever since. Variable fonts amplified the size advantage even further, a single variable WOFF2 file commonly replaces five or six static OpenType weights, cutting both bytes and HTTP request count. That round trip is one reason variable-font adoption took off so quickly once WOFF2 became universal, and why every modern type foundry now ships WOFF2 as the default web licence target.
- Default web font format for every public website built since 2018
- Variable fonts, where small file size matters most because variable fonts are large
- Mobile-first sites where bandwidth and battery matter
- Subsetted fonts shipping only the glyphs a page actually needs
What are the limits for WOFF2 conversion?
Size
The upload box shows the live size limit before you add a file. Signing in raises it, and paid plans raise it further.
Formats
WOFF2 converts to and from the other seven public font formats. The lists further down the page link to each pair.
Privacy
Files are uploaded to Cloudflare R2 storage for processing and are encrypted in transit.
Deletion
Free-tier files are deleted automatically after the job finishes. Signed-in output stays in your history for your plan's retention period.
Limits worth knowing
- Converting a file does not change its licence. Check that the licence lets you convert the font and embed it on the web.
- Converting between outline types can change how a font hints at small sizes, so test the result where you plan to use it.
- Keep the original font. A conversion writes a new file and leaves yours as it was.

WOFF2 FAQs
Why is WOFF2 the default web font format?
Two reasons. Brotli compression is roughly 30 percent more efficient than the zlib used in WOFF, and every browser released since 2018 supports it. The browser support tipped first; the size win locked it in.
Can I open a WOFF2 file in a font editor?
Most modern font editors handle WOFF2 directly. If yours does not, convert WOFF2 to TTF or OTF first, the underlying glyph data transfers cleanly with no quality loss.
How do I convert TTF to WOFF2?
Upload your .ttf file to our converter and pick WOFF2 as the target. The file you download is typically 60 to 70 percent smaller than the original TTF and is ready to ship via @font-face, no extra subsetting, hinting, or post-processing required to get a clean web-ready file.
Is the WOFF2 converter free?
Yes. Free conversions need no signup and add no watermark.
Do I need an account?
No. You can convert a font without signing up. Signed-in conversions use credits, and the result stays in your history.
Can I convert WOFF2 to other formats?
Yes. Every pair has its own page. The links under the conversion lists open them.
Am I allowed to convert and use any font?
Converting a file does not change its licence. Check that the licence lets you convert the font and embed it on the web before you publish it.
