Frequently asked questions
Is my WOFF 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 a WOFF file without installing software?
Drop the .woff file on this page. It opens straight away in the Font Viewer, on Windows, macOS, Linux, Android and iPhone alike.
What if my WOFF file doesn't open?
The viewer checks the file's content, not just its name. If it is damaged or not really a WOFF file, you'll see an error or can switch to the hex view to look at the raw bytes.
Can I convert WOFF to another format?
Yes. The free file converter turns WOFF files into other formats in your browser as well, without uploading them.
