I have created several 800X600 px images that contain only text, font size 14, Helvetica. Issue is when I export them to JPG at 72 PPI they look terrible – really pixelated. I have to increase the canvas size 2000 pixels + to get the text looking crisp. Where am I going wrong? I need 800x600px JPGs to work alongside the same size photographs. It’s for my photo website, not for print. Please help! I have a Mac 13inch retina laptop
