Drop WOFF 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 OTF, or download everything as one ZIP if you converted several files.
The WOFF to OTF 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.
WOFF cannot be installed on most computers, and WOFF2 is smaller. OTF carries advanced typographic features and works in every design tool. WOFF is at home in fonts on web pages, as a fallback for WOFF2; OTF is the usual choice for professional typography with ligatures and alternates.
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. A web font holds either TrueType or PostScript (CFF) outlines, and OTF can only be the matching kind. If the choice is wrong, the conversion stops and says whether TTF is the right one. A file that is not a TrueType, OpenType, WOFF, WOFF2 or collection font is refused.
WOFF is a TTF or OTF font with each table compressed, turning it into a lighter file for web pages. It became a W3C Recommendation in 2012 and every browser supports it. WOFF2 compresses further and has replaced it for new sites.

No. The WOFF to OTF 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: OTF 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 WOFF file, press Convert and save the OTF. 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.
