WOFF to EOT Converter
FileFlip converts WOFF to EOT entirely inside your browser, using the font engine compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a WOFF file to EOT?#
- Drop your WOFF file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to EOT and the conversion starts on its own. FileFlip downloads nothing at all, because everything it needs is already built into your browser, then runs the font engine on your own machine.
- Save the EOT file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting WOFF to EOT lose quality?#
No. The WOFF to EOT conversion copies the already-encoded streams into the new container without decoding them, so what comes out is bit-for-bit what went in. Only the wrapper changes, which is why it is also fast.
Is it safe to convert WOFF files online?#
Yes, because nothing is uploaded. FileFlip converts WOFF files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What WOFF to EOT actually does to the file#
Converting WOFF to EOT runs on the font engine, downloads nothing at all, because everything it needs is already built into your browser, copies the encoded streams into the new container without re-encoding them, keeps hinting and kerning, and drops OpenType features.
| Engine | the font engine |
|---|---|
| Conversion path | One step: WOFF → EOT |
| Downloaded to your browser | Nothing. Your browser already has everything this conversion needs |
| Quality | Lossless, repackaged rather than re-encoded |
| You get back | One file |
| Where it runs | On the page's own thread, so a very large file will make the tab wait |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Hinting | Kept | Carried through into the converted file. |
| Kerning | Kept | Carried through into the converted file. |
| OpenType features | Dropped | The target format has nowhere to put it. |
Worth knowing before you start:
- this conversion runs on the page's own thread, so a large file will freeze the tab while it works
What is a WOFF file?#
A WOFF file wraps a TrueType or OpenType font in a compressed container built specifically for loading with @font-face on the web.
Serve WOFF when a site's browser support has to reach back further than WOFF2 covers, or as the fallback source in a @font-face src list.
Convert WOFF to WOFF2 as the primary web font and keep WOFF only as a fallback, since WOFF2 is smaller for the same font on every modern browser.
What is an EOT file?#
An EOT file wraps a subsetted, compressed OpenType or TrueType font in a proprietary container that only Internet Explorer's @font-face implementation ever read.
There's no current reason to choose EOT; it only ever mattered for Internet Explorer 6 through 8, both long unsupported.
Convert away from EOT to WOFF2 and TTF for any website still shipping it, since no browser in current use reads EOT at all.
WOFF to EOT questions people ask#
Why is WOFF smaller than a plain TTF file?
WOFF wraps the same TrueType or OpenType glyph data inside a zlib-compressed container, which typically shrinks the file by more than 40 percent. Decompression happens once when the browser loads the font, so the smaller download comes at essentially no runtime cost.
Should I use WOFF or WOFF2 on my website?
WOFF2 compresses better than WOFF because it uses Brotli instead of zlib, and every browser still receiving updates supports it, so WOFF2 should be the primary format in a @font-face declaration. WOFF is worth keeping only as a fallback source for the handful of older browsers that never picked up WOFF2.
Can I install a WOFF file as a font on my computer?
Not directly. WOFF is a delivery format for the web, and operating systems expect an installable font like TTF or OTF rather than a WOFF container, so a WOFF file needs converting to TTF or OTF before Font Book or Windows Font Viewer will install it.
Do any current browsers support EOT fonts?
No. EOT only ever worked in Internet Explorer, and Microsoft Edge, IE's replacement, never implemented support for it. Every browser in current use needs WOFF, WOFF2, TTF or OTF instead.
