    What Refont does differently

    A report for every file

    Glyph count, kerning, features and variable axes, checked on the converted font, plus a plain statement of anything that had to change.

    A license check

    Every font carries an embedding setting from its maker. Refont reads it and warns you when the font is restricted, before you use the result.

    Real outline conversion

    OTF to TTF redraws every curve in TrueType form instead of renaming the file, and stays within one font unit of the original.

    Check that nothing is uploaded

    Every conversion runs inside your browser tab, using code that came from this site: a WebAssembly build of Google's WOFF2 library for web fonts, and fontTools, the library font foundries use, for rebuilding outlines. Nothing about your font is sent anywhere.

    You don't have to take our word for it. Open your browser's developer tools, switch to the Network tab and convert a font: you will see the converter's own code load, and no request carrying your file. Once the page has loaded, you can even go offline and keep converting.

    Commercial fonts often come with licenses that forbid uploading them to third-party services, which most online converters require. Converting locally avoids that problem entirely. It doesn't change what the license allows you to do with the result; the licensing guide explains what to check.

    Questions

    Is Refont free?

    Yes. There is no account, no file limit and no watermark.

    Which formats can it read?

    TTF, OTF, WOFF, WOFF2, TTC and OTC collections, Mac dfont, EOT, PostScript Type 1 (PFB and PFA, with AFM for kerning), and ZIP archives of any of these. Formats are recognised from the file contents, so a misnamed file still works.

    Why does OTF to TTF take longer the first time?

    Rebuilding outlines uses fontTools, which loads into your browser once (about 7.5 MB). Repacking conversions like TTF to WOFF2 don't need it and start immediately.

    Is converting a font legal?

    It depends on the font's license, not on the tool. Fonts under the SIL Open Font License, like most of Google Fonts, can be converted freely. Many commercial licenses restrict it. See the licensing guide.

    Are big fonts a problem?

    No upload means no size limit. Very large fonts, such as CJK families of tens of megabytes, just take longer and need enough free memory on your device.
