I have to make a logo for a customer and I would like to use a font from Google Font, but can I edit it on illustrator? I have seen that Google Fonts are also free for commercial use, but are they editable? I’m talking about convert the text to a vector outline and change some anchor points. Thank you!
If a license grants you commercial use, then yes you can create outlines and edit the glyphs in whatever manner you wish, unless otherwise stated in the license.
Most commercial licenses merely restrict the distribution or sharing of the actual font files themselves, not usage for the license holder.
(Note I used "most" because it's not impossible for a commercial license to restrict usage. I've simply never seen such a restriction myself.)
