What is a TTF file?

TrueType Font

Developed By
Apple Inc., Microsoft
Initial Release
1989
MIME Type
font/ttf

The TrueType Font (TTF) format is an outline font standard developed by Apple in the late 1980s and subsequently licensed to Microsoft to compete with Adobe's Type 1 PostScript fonts. TTF relies on quadratic Bézier curves to define glyph shapes and includes a robust hinting virtual machine that provides pixel-level control over rasterization, ensuring legibility at low resolutions. The file structure consists of a directory of tables (e.g., 'cmap' for character mapping, 'glyf' for outlines) and is standardized under ISO/IEC 14496-22.

How to open a TTF file

TrueType fonts are natively supported by virtually all modern desktop and mobile operating systems. In Windows, macOS, and Linux, opening a TTF file launches the default font management utility, allowing users to preview and install the typeface system-wide. While viewed easily at the OS level, modifying the internal vector paths or hinting instructions requires font editing tools like FontForge or BirdFont.

What is a WOFF file?

Web Open Font Format

Developed By
Mozilla, W3C
Initial Release
2010
MIME Type
font/woff

The Web Open Font Format (WOFF) is a wrapper format for TrueType (TTF) and OpenType (OTF) fonts, developed by Mozilla, Opera, and Microsoft and standardized by the W3C in 2012. WOFF applies zlib compression to the underlying font data to reduce latency and bandwidth usage during web page rendering. The format structure includes a unique header containing metadata and private data blocks, allowing for the inclusion of licensing information without altering the original font rendering data.

How to open a WOFF file

WOFF files are designed for interpretation by web browsers (Chrome, Firefox, Safari, Edge) via the CSS @font-face rule and are not intended for desktop installation. While they cannot be opened directly by OS font viewers, users can convert WOFF files back to desktop-compatible formats (TTF/OTF) using online converters or developer tools like FontForge. Developers can inspect WOFF resources using browser Developer Tools (F12).
