OTF (.otf, OpenType Font) is a font format jointly developed by Microsoft and Adobe in 1996 as the successor to TrueType. It supports cubic Bezier curves (PostScript outlines), advanced typographic features (ligatures, contextual alternates, small caps, old-style figures), and has comprehensive Unicode coverage.

Are my OTF files uploaded?

No. Font files you open from your device stay on your device and are rendered locally. Only the public sample font is requested from the server.

Which format should I use: TTF or OTF?

For modern use, OTF is generally preferred because it supports more advanced features and has better cross-platform compatibility. However, TTF may render better at small sizes due to superior hinting in some cases. Both formats are widely supported.
