What is a WOFF file?

The WOFF extension is related to Web Open Font Format and is classified in the Font Files category, which contains 102 files.

WOFF files are supported by Windows, Mac OS and Linux. When working with WOFF files, you can rely on 11 programs, including FontCreator, Birdfont and FontForge.

How to open a WOFF file?

If you can’t open a WOFF file, it is usually because the necessary software is missing. To resolve the issue, select the right program from the list for your operating system. Then go to the official website of the developer, download the software, and install it.

FontCreator, Birdfont and FontForge stand out as the preferred programs to manage WOFF files effectively. To get the latest version of FontCreator, open the High-Logic B.V website where a universal installer for all operating systems is available.

After setup, the operating system should recognize WOFF files and link them with FontCreator.

Set FontCreator as your default WOFF viewer

Set default app to open files on Mac

  1. Right-click or Control + left-click on the desired WOFF file to open a menu of available actions;
  2. Choose "Open in Application" and click "Other";
  3. Scroll down to the bottom of the window, and there you will find the "Enable" menu. The default selection is "Recommended Programs";
  4. Choose "All Programs" within this menu and locate FontCreator. Check the box next to "Always open in app" to set it as the default program.

Set default programs for Windows

  1. Take the first step by right-clicking on your WOFF file. Next, select "Open With" and then choose "Choose another app" from the available options;
  2. From the list of applications in the pop-up window, find and select FontCreator as your desired application;
  3. Check the "Always use this app" checkbox, and then click "OK" to set your chosen app as the default for opening WOFF files.

Convert files to and from WOFF

If a WOFF file is difficult to handle, you might try converting it to formats such as OTF or similar, which may be easier to work with.

Be aware that converting a WOFF file may reduce some features, but you can usually revert it to the original format.

Offline conversion tools, like FontCreator, provide reliable and high-quality conversion of WOFF files.

Solving Common WOFF File Challenges

WOFF files can sometimes be tricky, but minor software adjustments usually resolve the issues. Refer to the tips below for guidance.

How do I know if my WOFF file has been damaged?

WOFF font files that have become corrupted may display one or more of the following symptoms:

  • Error alerts occur when actions are performed on the file;
  • The file exhibits poor performance during editing operations in FontForge;
  • The file does not respond or shows errors when opening it;
  • Unexplained WOFF file size inflation;
  • The file stops responding or freezes in FontCreator or other programs;

Why does FontCreator quit or crash unexpectedly?
