Convert the OTF font to WOFF. WOFF is lighter and is used on websites with @font-face.
Drag one or more OTF files onto the dashed area, or tap it to pick them from your device.
WOFF is already selected; the options hold the settings that matter for this conversion.
Press “Convert to WOFF”. When it’s done, download the files one by one or all together in a ZIP archive.
Good to know. Always check that the font’s licence allows conversion and use on the web.
Source format
OpenType Font
The evolution of TrueType created by Microsoft and Adobe: it supports ligatures, stylistic alternates and thousands of characters. It’s the format of professional fonts.

Web Open Font Format
A TrueType or OpenType font compressed and packaged for websites: it weighs less and loads faster. Computers, though, don’t install it as a system font.

Up to 100 files at a time. There’s no fixed size limit: it depends on your device’s memory. On smartphones it’s best to work in smaller batches with heavy files such as videos.
Yes, with up-to-date Safari, Chrome, Firefox, Edge and Samsung Internet. On phones, converted files end up in the Downloads folder or the Files app.
Only to open the page (and, the first time, to download the components needed for that type of file). After that the conversion keeps working even if the connection drops.
