EOT to WOFF Converter
Processing entirely on your device — large files may take a moment.
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. Converting WOFF back to TTF/OTF unlocks fonts trapped in old web projects for desktop install and editing.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How EOT compares to WOFF
| EOT | WOFF | |
|---|---|---|
| Compatibility | IE4-8 only; extract for everything else | IE9+ and all modern browsers |
| Best for | Rescuing fonts from legacy web archives | Legacy-browser web fonts |

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 WOFF format
WOFF (Web Open Font Format, 2010) wrapped TTF/OTF data in a web-first container: zlib compression (~40% smaller), strict table structure, and optional license metadata that foundries required before allowing web embedding. It powered the first generation of real web typography under @font-face.
Its successor WOFF2 compresses better with Brotli and has since become the only format modern sites ship. WOFF remains useful for one reason: legacy browsers (IE9–IE11 era) that never learned WOFF2.
+Strengths
- ✓Compressed and web-legal by design
- ✓Works back to IE9-era browsers
!Limitations
- −Superseded by WOFF2 everywhere current
- −Larger than WOFF2 for identical glyphs
Why convert EOT to WOFF?
There is a concrete reason this conversion exists: Dead format — no modern browser loads it WOFF sidesteps that — Compressed and web-legal by design If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this EOT to WOFF 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 WOFF?
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.
Does converting EOT to WOFF 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.
Can I install the WOFF file on my computer?
That depends on the target: desktop systems install TTF/OTF files directly, while WOFF is a web container meant to be served with @font-face rather than installed. Keep the original for desktop use.
