How to inspect TTF, OTF, WOFF, WOFF2 files

A one-line preview cannot prove character coverage, embedding rights, or correct metrics. This tool reads internal font tables but does not replace the license text.

  1. Choose a TTF, OTF, WOFF, or WOFF2 font.
  2. Review family, subfamily, PostScript name, version, and copyright records.
  3. Search a Unicode character and inspect its mapped glyph.
  4. Test text, kerning, and variable axes; export or embed only when licensed.

What this tool helps with

  • Check whether a font contains a target CJK character or symbol
  • Inspect internal names, metrics, and variable axes
  • The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.

Compatibility and limitations

  • Font metadata is not complete legal permission
  • Complex GSUB/GPOS, color glyphs, and hinting may be partially represented
  • No circumvention of encryption, DRM, or embedding restrictions

Frequently asked questions

How do I check a missing character?

Search the character; a Unicode mapping to a valid glyph indicates it is present.

Does a Free copyright field allow commercial use?

Not by itself. Read the bundled license and confirm the intended use.

Is the font uploaded?

The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.
