What is an EOT file?
EOT (Embedded OpenType) is a web font format designed by Microsoft for use with Internet Explorer. It was created to allow TrueType and OpenType fonts to be embedded in web pages while supporting DRM-like URL binding. EOT has been largely replaced by WOFF and WOFF2 but is still needed for IE8 compatibility.
How to open EOT files
- Internet Explorer (Windows) — Native rendering
- Web browsers — Only IE supports EOT natively
- FontForge (Windows, macOS, Linux) — Free font editor
- ttf2eot — Command-line converter
