I keep trying to export 300dpi PNGs from Illustrator, on a 1500x1500 px artboard, and they keep turning out really small and pixelated, not big, beautiful, and vector-like as usual! Help!
You can also select the element and copy it to your clipboard. Then Alt+Tab to Photoshop and choose new CMD+N. From there change the width and height units from pixels to a unit of measurement. Alter the resolution to your liking. Click create then paste just paste your artwork to the new artboard.
