Is there a way to do this? This is my first time trying to make glyphicons and icomoon ignores strokes. I have quite a few, so was hoping there were some veteran designers that could point me in the right direction to the quickest way of converting strokes to fills.
Select the shapes that you want to convert and choose Layer → Convert to Outlines
Just select all if you want everything to be converted.
Sketch has removed support for convert-to-outline for paths. You can do it by exporting your item as svg from sketch and then converting it to shapes-only using this free online tool: https://www.ofoct.com/image-converter/svg-optimizer.html
