EOT to WOFF2 Converter
Processing entirely on your device — large files may take a moment.
Embedded OpenType and Web Open Font Format 2 exist for different jobs: EOT is Microsoft's web font format for IE4-IE8 — a TTF wrapped in a header with embedding permissions. The raw TTF rides at the tail of the file. Convert to WOFF2 before shipping any font to a website — it is the smallest and fastest-loading option browsers support.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How EOT compares to WOFF2
| EOT | WOFF2 | |

About the EOT format
EOT (Embedded OpenType) is Microsoft's answer to web fonts from 1997: a TTF wrapped in a header carrying embedding permissions, root-string domain locks and a URI table — designed so foundries could license fonts for the web without giving away the raw file. IE4 through IE8 required it.
The actual sfnt rides unchanged at the tail of the file, so extraction is a pure slice: read FontDataSize from the header, take that many bytes from the end, and you have a TTF every modern browser accepts.
+Strengths
- ✓Carries embedding-permission metadata
- ✓Lossless TTF recovery from the tail
- ✓Required reading for legacy IE archives
!Limitations
- −Dead format — no modern browser loads it
- −Header variants (compression flags) exist
- −Root-string locks are trivially stripped
About the WOFF2 format
WOFF2 (W3C, 2014) is the current standard of web fonts: the same TTF/OTF outlines compressed with Brotli, typically 30% smaller than WOFF and dramatically smaller than raw fonts, plus a table-transform optimization that shrinks glyf data further. Every browser since 2016 decodes it; no modern site ships anything else.
It is strictly a web container — you cannot install a WOFF2 into the OS directly — so the workflow is one-way: desktop font (TTF/OTF) converts to WOFF2 for the site, while the source file stays for design tools. Pair it with `font-display` and subsetting for maximum loading speed.
+Strengths
- ✓Smallest web font format (Brotli + transforms)
- ✓Universal modern browser support
- ✓Works with both TTF and OTF outlines
!Limitations
- −Not installable on desktop directly
- −No support in IE-era browsers
Why convert EOT to WOFF2?
There is a concrete reason this conversion exists: Dead format — no modern browser loads it WOFF2 sidesteps that — Smallest web font format (Brotli + transforms) If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this EOT to WOFF2 converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for EOT to WOFF2?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Can I install the WOFF2 file on my computer?
That depends on the target: desktop systems install TTF/OTF files directly, while WOFF2 is a web container meant to be served with @font-face rather than installed. Keep the original for desktop use.
Does converting EOT to WOFF2 change how the font looks?
No. The glyph outlines are carried over as they are — conversion changes the container and compression, not the shapes your users see.
