Frequently asked questions
Is my OTF file uploaded?
No. The file is read by your browser and shown on your own device. Nothing is sent to a server, and it is gone when you close the tab.
How do I open an OTF file without installing software?
Drop the .otf file on this page. It opens straight away in the Font Viewer, on Windows, macOS, Linux, Android and iPhone alike.
What if my OTF file doesn't open?
The viewer checks the file's content, not just its name. If it is damaged or not really an OTF file, you'll see an error or can switch to the hex view to look at the raw bytes.
Can I convert OTF to another format?
Yes. The free file converter turns OTF files into other formats in your browser as well, without uploading them.
