TTF to WOFF2 is the step that turns a desktop font into a font a website can load quickly.
A TTF file works well on a computer, but it is not built for the web. A WOFF2 file is built for the web, and it is much smaller than the TTF file it came from.
That size change is what makes the conversion worth doing. A website that loads a smaller font file has less font data to download before the text can appear. Visitors see the page sooner, and the site feels faster, especially on a slow connection.
What is a WOFF2 file?
A WOFF2 file is the modern web font format. It holds the same font design as the original font, but in a compressed form made for websites. When a browser loads a page, it can download the WOFF2 file and use it to show the page text in that font.
| Feature | TTF | WOFF2 |
|---|---|---|
| Typical use | Desktop font | Web font |
| File size | Larger | Much smaller |
| Best for | Installing on a computer | Loading on a website |
Pro tip: Keep your original TTF file after converting, so you always have the desktop version if you need it again later.
Font Licensing
Converting a font does not give you the legal right to use it on a public website. You must have a web license for the font. That point is easy to miss, because the conversion itself is a technical step, and it says nothing about permission.
A font license controls how you may use a font. A license that allows installing a font on your own computer does not automatically allow publishing that font on a public website. Web use is a separate use, and it needs a web license.
This page is not legal advice, and the tool cannot check your license for you. If you are unsure whether your license allows web use, check the license terms or ask the font provider before you publish the font on a website.
Pro tip: Save a copy of your web license with your website files, so you can find it quickly if the permission question comes up later.
Convert TTF to WOFF2 without uploading
You can convert TTF to WOFF2 without uploading your font to a server. That upload step is the part many existing tools require, and it is the part that worries people most when the font is proprietary or licensed.
This web font converter does the work in your browser. It takes the uploaded TTF file, compresses the font into WOFF2 form using browser processing, and offers the result as a download. Your job shifts from moving a font between tools to checking the WOFF2 file.
Pro tip: Convert a copy of your font, not your only copy, so the original TTF file stays untouched if anything goes wrong.
Checking the WOFF2 file before publishing
Automatic conversion gives you a web font file, but it does not give you a finished check. The WOFF2 file should open as a font file, and it should show the same letters, numbers, and symbols you expect from the original font.
Open the WOFF2 file on a test page and look at the text closely. Check headings, body text, and any special characters your site uses. If a character looks wrong or missing, do not publish the file yet, and convert again from the original TTF file.
If you need the reverse direction later, the WOFF2 to TTF converter turns a web font back into a desktop font.
Pro tip: Test the WOFF2 file in the browsers your visitors use, not just in one browser, before you publish it on a live site.
