Drop OTF (OpenType) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the WOFF2, or download everything as one ZIP if you converted several files.
The OTF to WOFF2 converter is part of this page and runs inside your browser. Your fonts are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
OpenType fonts keep their PostScript outlines and typographic features, such as ligatures and alternates, when wrapped as WOFF2. WOFF2 is the smallest font format browsers load, so it is the one to serve from a website. Confirm that the font's licence allows web embedding.
The outlines and tables of the font are copied unchanged and only the wrapper around them changes, so the letterforms, hinting and layout features are exactly the same. WOFF2 is handled by a WebAssembly module that downloads the first time you compress to WOFF2 and is cached; WOFF2 reorganises the outline tables, so converting back gives the same glyphs but not an identical file. A file that is not a TrueType, OpenType, WOFF, WOFF2 or collection font is refused.
OpenType extends TrueType with layout features such as ligatures, small capitals and alternate letterforms, and can hold either TrueType-style or PostScript (CFF) outlines. An .otf file usually contains the CFF kind. It is the usual format for professional type families.

OTF converterWOFF2 compresses a font with Brotli after reorganising its outlines, producing files roughly a quarter to a third smaller than WOFF. It became a W3C Recommendation in 2018 and is the font format sites should serve to current browsers.

No. The OTF to WOFF2 conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
No further quality is lost: WOFF2 stores the decoded audio exactly. The result is identical in content.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the OTF file, press Convert and save the WOFF2. There is nothing to install.
Yes. Fonts up to 100 MB are accepted, which covers all but the very largest CJK families. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
