I'm a volunteer for social media graphics and when I create graphics I use the "Save for Web" option and either use the PNG-8 or PNG-24 when I save, but the graphic is still distorted and messy. I do freelance onsite and when I create graphics there with those save options I have no problem. I believe its in the settings, so if someone can point out where I can go that would be great. Thanks!
Could you please provide relevant information and examples?
