Enhancing png signatures - General Questions - Krita Artists

I was asigned a duty to make a design for T-shirts for the end of elementary/junior high school and I had to put our signatures on the back, so I took a graphic tablet and saved all people’s signatures as png. Now some of them have too narrow font and if I want it to be visible when printed on the shirts I have to make them more thick. Does anyone know how to make lines more thick (not necessary in krita) and would help me with this?
