Are my WOFF files uploaded anywhere?

Yes — this conversion needs software that cannot run in a browser, so the file is uploaded over an encrypted connection. It is deleted as soon as the job finishes, and the result is removed after 60 minutes.

Is converting WOFF to OTF free?

Yes, up to 100 conversions a day for files up to 25 MB. That one limit exists because this conversion runs on a server we pay for; nothing else here is metered, and there is no watermark either way.

Does converting WOFF to OTF lose quality?

No. OTF stores the same content without discarding anything, so the result is identical in quality to the original. The outlines decide what an unwrapped font is: a WOFF holding PostScript curves becomes an OTF, one holding TrueType curves becomes a TTF. Asking for the other is refused rather than answered with a mislabelled file.

Do I need to install anything to open OTF files?

No. The conversion runs on our side and gives you a finished OTF file; opening it needs whatever software normally handles OpenType Font.
