I have a logo someone did for me on Fiverr a year ago and I have the vector.ai file but need a program to open and make changes like bigger and darker wording. I'm very green and hope to make videos to promote my business. They say .png files work best but, the ones they sent don't look good enough. The prson that did it is no longer on Fiverr (go figure). Any help would be greatly appreciated! TIA.
