Convert SVG Strokes To Fills
Documentation, Installation, and Usage Instructions
See the full installation and usage documentation HERE.
The Objective
I wanted to convert some svg icons to fonts using tools like icomoon.io, fontello.com and webfont
The Problem / Why
If your svg containts strokes or any tags besides a single path e.g polygon rect line etc, you will get these errors when trying to convert them into fonts.
Example
SVG
Icon -> we will be using in this example
Code -> for the icon
<svg
xmlns="http://www.w3.org/2000/svg"
width="24"
height="24"
viewBox="0 0 24 24"
fill="none"
stroke="currentColor"
stroke-width="2"
stroke-linecap="round"
stroke-linejoin="round">
<rect x="3" y="3" width="18" height="18" rx="2" ry="2" />
<line x1="9" y1="9" x2="15" y2="15" />
<line x1="15" y1="9" x2="9" y2="15" />
</svg>Errors
When we try to convert this SVG into a font using one of these SVG To Font conversion tools we get the following errors.
| icomoon.io error | fontello.com error | webfont error |
|---|---|---|
 |
 |
 |
Ignoring The Errors
What happends if you ignore these errors? well, the font pack with the icon(s) will come out "corrupt/incorrect", different than expected or not even render at all (blank).
Results From Ignoring The Errors
The icon not showning up or rendering in the font pack when we ignore the errors and just create the font anyway.
| icomoon.io blank | fontello.com blank | webfont blank using fontdrop.info to preview the font |
|---|---|---|
 |
 |
 |
The Solution
I created this package to solve this issue, now you can "fix" svg icons to make then font compatable by running them through SVGFixer.
Fixing The Icon
The icon in a font pack after we run it through SVGFixer().
| icomoon.io fixed | fontello.com fixed | webfont fixed using fontdrop.info to preview the font |
