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).

What is an EOT file?

Embedded OpenType

Developed By
Microsoft
Initial Release
1997
MIME Type
application/vnd.ms-fontobject

The Embedded OpenType (EOT) format is a legacy font file standard developed by Microsoft in 1997 specifically for use with Internet Explorer. It functions as a compact wrapper for TrueType (TTF) and OpenType (OTF) fonts, utilizing MicroType Express compression to reduce file size for web transmission. EOT files employ a proprietary structure that includes embedding permission flags to prevent unauthorized usage, adhering to Digital Rights Management (DRM) protocols. While submitted to the W3C in 2008, it was eventually superseded by WOFF, though it remains relevant for supporting older browser versions like IE8 and below.

How to open an EOT file

EOT files are designed exclusively for web rendering by the Trident layout engine found in Microsoft Internet Explorer. They are not intended for direct opening or installation on a local operating system like Windows or macOS. To view or edit the glyph data contained within an EOT file, users must convert it back to a TTF or OTF source format using specialized font engineering software such as FontForge or online conversion utilities.
