WOFF to WOFF2 Converter

What happens when you convert WOFF to WOFF2

• FontForge, the open-source font editor, unpacks the WOFF on our conversion server and writes the font as WOFF2.
• WOFF2 restructures the glyph data and compresses the whole font with Brotli, so it is usually about 30 percent smaller than WOFF and far smaller than the original font. The outlines, kerning, hinting and OpenType features are unchanged.
• WOFF2 is for websites: load it with @font-face in CSS. It cannot be installed on a computer, so keep the original font for that.
• This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.

Why convert WOFF to WOFF2?

WOFF loads in every browser through CSS; cannot be installed on a computer, while WOFF2 loads in every current browser through CSS; cannot be installed on a computer.

WOFF vs WOFF2: the differences

About WOFF and WOFF2 files

What is a WOFF file?

WOFF is a TrueType or OpenType font with each table compressed and a small header added, which makes web fonts smaller to download. The font inside is unchanged.

What is a WOFF2 file?

WOFF2 compresses a font with Brotli and restructures its glyph data first, so it usually comes out around 30 percent smaller than WOFF. Every current browser supports it, which makes it the format to serve on the web today.

WOFF to WOFF2 not working? Common problems

• "Files up to 25 MB can be converted." Server conversions have a size limit. A font that large usually holds several scripts; subset it to the characters you need first.
• "The conversion took too long and was stopped." Very long or complex files can pass the 90 second limit. Split the file and convert the parts.
• "This file is not really in WOFF format." The converter checks every file before it runs anything, so a file of another format renamed to .woff is refused. Choose the page for its real format.

Convert WOFF to WOFF2 from the command line

FontForge does the same on your own computer:

fontforge -lang=py -c "import fontforge, sys; fontforge.open(sys.argv[1]).generate(sys.argv[2])" input.woff output.woff2

Converting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
