SVG Font to WOFF Converter
FileFlip converts SVG Font to WOFF 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 an SVG Font file to WOFF?#
- Drop your SVG Font 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 WOFF 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 WOFF file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting SVG Font to WOFF lose quality?#
No. The glyph outlines are converted between outline models rather than redrawn, so the letterforms in the WOFF file are the ones in the SVG Font file. What can change is the hinting and the OpenType tables around them.
Is it safe to convert SVG Font files online?#
Yes, because nothing is uploaded. FileFlip converts SVG Font 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 SVG Font to WOFF actually does to the file#
Converting SVG Font to WOFF runs on the font engine, downloads nothing at all, because everything it needs is already built into your browser, converts the glyph outlines between outline models, keeps hinting and kerning, and drops OpenType features.
| Engine | the font engine |
|---|---|
| Conversion path | One step: SVG Font → WOFF |
| Downloaded to your browser | Nothing. Your browser already has everything this conversion needs |
| Quality | Outlines preserved |
| 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 an SVG Font file?#
An SVG font file defines each glyph as an SVG path inside a font element, an XML-based approach the SVG 1.1 specification allowed and that SVG 2 has since removed.
There's little current reason to choose SVG fonts for web text; icon font systems built years ago are the main place they still appear.
Convert an SVG font to WOFF2 for anything meant to render as text in a current browser, since SVG font support is largely gone.
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.
SVG Font to WOFF questions people ask#
Why were SVG fonts deprecated?
SVG 2 removed the font-specific elements, like glyph and font, that SVG 1.1 had defined, pointing to WOFF as the format browsers should use for web fonts instead. WOFF and WOFF2 compress better and reuse the existing TrueType and OpenType glyph model, which made a separate SVG-based font format redundant.
What's the difference between an SVG font and a regular SVG icon set?
An SVG font defines glyphs inside a font element so text can reference them by character, the same way a browser looks up a letter in TTF or WOFF. A regular SVG icon set is just a collection of separate SVG files or symbol elements, each inserted directly rather than looked up as a character, which is why icon systems moved to plain SVG sprites once SVG font support started disappearing from browsers.
Do browsers still support SVG fonts?
Barely. Chrome removed support in version 38 back in 2014 and Opera followed soon after, while Firefox and Edge never implemented SVG fonts at all. Safari is the one major browser that still renders them, which makes SVG fonts unreliable for any site that needs to work everywhere.
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.
