Free online TTC to WOFF2 converter

Source format: TTC

TTC stands for TrueType Collection. It is a font container format that bundles multiple TrueType fonts into a single file, often sharing common glyph data to save space. TTC files are commonly used by Windows, macOS, and some Linux font packages, especially for large font families such as CJK fonts, system font sets, and bundled typefaces distributed by operating systems or software suites.

TTC is useful when several related font faces need to be installed together, such as regular, bold, italic, and regional variants. Because it is a collection rather than a single font, it is often encountered in system font directories and professional font distributions.

Target format: WOFF2

WOFF2 stands for Web Open Font Format 2. It is a compressed web font format designed for fast delivery in browsers. Compared with older font formats, WOFF2 usually provides smaller file sizes and efficient loading, which makes it the preferred format for modern websites.

WOFF2 is widely supported by current browsers and is commonly used for web typography, branding, and responsive design. Its main advantages are reduced bandwidth usage, faster page rendering, and broad compatibility with modern web platforms.

How to perform the conversion

Converting TTC to WOFF2 usually means extracting one font face from the collection and saving it as a web-optimized font. The best desktop tools for this are FontForge and fonttools (with the WOFF2 support package installed).

Method 1: Using FontForge

1. Open the TTC file in FontForge.
2. If the file contains multiple faces, choose the specific font face you want to export.
3. Check the font name, glyph coverage, and licensing before web use.
4. Use File → Generate Fonts.
5. Select WOFF2 as the output format.
6. Save the exported file with a .woff2 extension.

Method 2: Using fonttools

1. Install the tools and WOFF2 support, then open a terminal.
2. Extract the desired face from the collection if needed.
3. Convert the font to WOFF2 using the appropriate fonttools command for your environment.
4. Verify that the output file opens correctly in a browser or font inspector.

If you only need a quick conversion without installing software, you can convert the file on 101convert.com for free.

Typical workflow tip: if your TTC contains multiple fonts, convert each required face separately so you can use them individually in CSS with @font-face.

Notes on quality, compatibility, or limitations

TTC to WOFF2 is not always a one-to-one conversion. A TTC may contain several fonts, while WOFF2 stores a single font file per output. That means you usually need to choose one face at a time or create multiple WOFF2 files from the collection.

Some TTC fonts include features or tables that may not be preserved perfectly during export, especially if the source font is complex or partially unsupported by the conversion tool. Always test the resulting WOFF2 in target browsers and check that the glyphs, weights, and styles render correctly.

Also note that font licensing matters: many system TTC fonts are not licensed for web embedding. Before publishing a converted WOFF2 file on a website, confirm that the font license allows web use and subsetting if applicable.

For best results, use a modern conversion tool that supports WOFF2 compression and validate the output with browser testing or a font inspection utility.
