If you’re experiencing issues with an OTF font, we recommend that you completely uninstall the OTFs and try the TTF fonts instead. While most programs support OTFs, some software (especially older programs) only support TTFs or exhibit strange behavior when using OTFs. OTF files tend to be significantly smaller than their TTF counterparts.Read more about Opentype features in our article OpenType 101 and blog post Typographic Feng Shui And OpenType. OTF files may contain additional alternative characters and typesetting features, including contextual alternatives, that can be used in supporting applications.If you need OTF files, ask our support team for OTF files and we’ll try to acquire these for you.Ĭheck out our support articles for installing fonts on Windows and installing fonts on Mac. If the OTF files are unavailable there won’t be a dropdown arrow next to the download button. In the rare case that the foundry hasn’t provided us with OTF files, clicking the download button will instead download the TTF files.
