What happens when you convert WOFF2 to OTF
- Google's woff2 tools unpack the WOFF2 on our conversion server, restoring the TrueType or OpenType font inside.
- If the font inside already has the outline type OTF normally holds, it is returned as it is; otherwise FontForge converts it.
- If the font has TrueType (quadratic) outlines, FontForge redraws them as PostScript (cubic) curves in a CFF table, the usual content of an .otf. The shapes are the same, but TrueType hinting is dropped, so small sizes on Windows may render a little differently.
- Double-click the result to install it on Windows or a Mac, provided the font's licence allows desktop use.
- 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.
How to convert WOFF2 to OTF online
- Press "Choose WOFF2 files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to OTF". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
- Save each OTF with its download button. Our server has already deleted both your WOFF2 and the OTF by then.
Why convert WOFF2 to OTF?
WOFF2 files usually come from fonts served by modern websites. People convert them to OTF when a design program, print workflow or font tool expects PostScript (CFF) outlines, which is what an .otf file usually holds.

About WOFF2 and OTF files
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.
What is an OTF file?
OpenType extends TrueType with advanced typography such as ligatures and alternate glyphs. An .otf file usually holds PostScript-style cubic outlines rather than TrueType curves.
WOFF2 to OTF 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 WOFF2 format." The converter checks every file before it runs anything, so a file of another format renamed to .woff2 is refused. Choose the page for its real format.
Convert WOFF2 to OTF from the command line
Google's woff2 tools unpack the font on your own computer; FontForge then changes its outline type if needed:
woff2_decompress input.woff2
fontforge -lang=py -c "import fontforge, sys; fontforge.open(sys.argv[1]).generate(sys.argv[2])" input.ttf output.otfConverting 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.
WOFF2 to OTF converter FAQ
Will I lose quality converting WOFF2 to OTF?
If the font inside already has OTF outlines, it comes back exactly as it was packed. If its outlines are converted, the glyphs look the same, though hinting can change at small sizes on Windows.
Why is the OTF a different size from the WOFF2?
Much larger than the WOFF2, because the font is no longer compressed.
Are my WOFF2 files uploaded?
Yes, for this conversion. A faithful WOFF2 to OTF conversion needs Google's woff2 tools and FontForge, the open-source font editor, which cannot run in a browser. The file travels over an encrypted connection, is converted in a private temporary folder, and is deleted together with the OTF as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several WOFF2 files to OTF at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open an OTF file?
OTF installs on Windows, Mac and Linux; browsers load it through CSS. OTF is common for professional typography, ligatures and design work.
Is this WOFF2 to OTF converter free?
Yes. There is no sign-up and no watermark. Because this conversion uses our server, there is a fair-use limit of 25 MB per file and a number of files per hour, which stops the service being overloaded.
Can I convert WOFF2 to OTF on my phone?
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The conversion happens on our server, so it is as fast on a phone as on a computer; the OTF is saved to your Downloads folder.
