WOFF2 to EOT Converter
FileFlip converts WOFF2 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 WOFF2 file to EOT?#
- Drop your WOFF2 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 0.7 MB of WebAssembly the first time and nothing after that, 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 WOFF2 to EOT lose quality?#
No. The WOFF2 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 WOFF2 files online?#
Yes, because nothing is uploaded. FileFlip converts WOFF2 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 WOFF2 to EOT actually does to the file#
Converting WOFF2 to EOT runs on the font engine, downloads 0.7 MB of WebAssembly the first time and nothing after that, 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: WOFF2 → EOT |
| Downloaded to your browser | 0.7 MB, once, then cached by your browser |
| 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 WOFF2 file?#
A WOFF2 file wraps a TrueType or OpenType font in a Brotli-compressed container built for @font-face delivery on the web, replacing WOFF's older zlib compression.
Serve WOFF2 as the primary font format for any website, since it's the smallest option every current browser supports.
Convert away from WOFF2 only when a font needs to be installed on a desktop or opened by a font editor, since WOFF2 exists purely for web delivery.
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.
WOFF2 to EOT questions people ask#
How much smaller is WOFF2 than WOFF?
WOFF2 typically comes in around 30 percent smaller than the same font packaged as WOFF, because it replaces WOFF's zlib compression with Brotli and adds a font-specific preprocessing step before compressing. The exact saving varies by font, but it's consistent enough that WOFF2 is the default choice for new @font-face declarations.
Do I still need WOFF if I'm using WOFF2?
Only for older browsers. Every browser still receiving security updates supports WOFF2, so a WOFF fallback in the @font-face src list mainly protects against very old or niche browsers that never added WOFF2 support, most notably Internet Explorer.
Can I install a WOFF2 file as a system font?
Not directly. WOFF2 is a web delivery format, so Windows, macOS and Linux font installers don't recognize it, and it needs converting to TTF or OTF before an operating system will install it as a usable font.
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.
