Free Font Metadata Viewer Online

A font file is more than just shapes. Embedded inside every TTF, OTF, and WOFF file is a set of metadata tables: the family name, the designer's name, the license text, the copyright notice, the version number, how many glyphs are included, and a set of embedding permission flags that control how the font can legally be used.

Most operating systems surface almost none of this. Windows shows you the font name and a preview. macOS Font Book shows slightly more. Neither shows you the license text, the embedding flags, or the full unicode range coverage.

This tool reads font metadata directly in your browser. No install, no extension, no file upload.

What Is Stored in Font Metadata

Font files store their metadata in standardized internal tables. The fields this tool surfaces include:

• Family name — the full name of the font family as declared by the designer
• Designer — the name of the type designer or foundry
• Version — the version string of the font file (e.g., "Version 1.003")
• Copyright — the copyright notice embedded by the font creator
• License text — the full license terms, if embedded (many commercial fonts include this)
• License URL — a link to the full license, often for OFL or Apache-licensed fonts
• Glyph count — total number of glyphs in the font
• Weight class — numeric value (100–900) indicating the font's weight
• Unicode ranges — which Unicode blocks the font covers (Latin, Cyrillic, Greek, etc.)
• Embedding permissions (fsType) — flags controlling whether the font can be embedded in documents, web pages, or editable files

This is the same data that font management tools like FontLab and professional type specimen services expose — just accessible instantly from a browser.

How to View Font Metadata Online

Using the WildandFree Font Metadata Viewer takes about five seconds:

1. Click the upload area or drag your TTF, OTF, or WOFF file onto it
2. The file is read locally in your browser — nothing is transmitted
3. All available metadata fields appear immediately below

You can view multiple fonts in one session by loading a new file. The results update instantly each time.

If a field isn't shown, it means the font author didn't embed that value — which itself is useful information. Many older freeware fonts omit the license field entirely, which is a red flag for commercial use.

Why You Should Check Font Metadata Before Using a Font

For casual personal use, font metadata is optional reading. For professional, commercial, or web use, it matters in three specific ways:

License compliance: The license text and license URL fields tell you exactly what the font permits. Some fonts are free for personal use but require a commercial license for client work. The metadata is the authoritative source — not the download site's description.

Web embedding legality: The fsType embedding flags tell you whether a font is cleared for web embedding via @font-face. A font that restricts embedding legally cannot be used in a stylesheet, even if you technically own a copy. See the full guide on fsType flags for more detail.

Version tracking: When you receive a font from a client or collaborator, checking the version string tells you whether you have the same version they're using. Mismatched font versions cause subtle layout differences that are notoriously hard to debug.

Which Font Formats Are Supported

The viewer supports TTF (TrueType), OTF (OpenType), and WOFF (Web Open Font Format). These cover the vast majority of font files in everyday use.

WOFF2 files are a compressed format primarily used in web delivery — the metadata they contain is the same as the underlying TTF or OTF source. To inspect a WOFF2 file's metadata, the cleanest path is to convert it back to TTF or OTF first using the Python fonttools library, then open the result here.

BDF and bitmap font formats aren't supported — those use a different, text-based structure that predates the OpenType standard.

Your Font Files Stay on Your Device

The viewer processes everything locally in your browser. Your font file never leaves your device — no upload, no server, no third-party processing.

This matters if you're working with proprietary fonts licensed to your organization, pre-release typefaces, or client-provided brand assets. You can inspect their metadata without any risk of the file being logged, cached, or retained anywhere.

The trade-off is that some cloud-based metadata tools offer editing or batch processing. This tool is read-only. If you need to edit embedded metadata, the standard tool for that is fonttools (Python) or a dedicated font editor like FontForge.

Frequently Asked Questions

What is font metadata?

Font metadata is information embedded inside a font file — the family name, designer, version, copyright notice, license terms, glyph count, and embedding permissions. It's stored in standardized internal tables and isn't visible just by looking at the font's glyphs.

Can I edit font metadata with this tool?

No — this tool is a viewer only. It reads and displays the metadata embedded in the font file. To edit font metadata, you'll need fonttools (Python), FontForge, or a commercial font editor like FontLab.

Does the tool support WOFF2?

Not directly. WOFF2 is a compressed delivery format. To inspect its metadata, convert the WOFF2 back to TTF or OTF first (fonttools can do this), then open it here.
