The Export for screens feature in Illustrator lets you export artboards in different file formats intended for digital display, including png, jpg, SVG, and pdf. Export for screens allows you to export multiple artboards at a time unlike the old Save for web feature where you had to export artboards one at a time. The export options for PNG format are PNG and PNG 8. PNG is the standard 24-bit PNG and PNG 8 is 8-bit PNG. 24-bit PNG images are able to carry more color information than 8-bit PNGs. For better color accuracy, Export your artboard as a PNG (i.e., PNG 24). Your PNG export will be larger than PNG 8. The export options for JPG format are JPG 100, JPG 80, JPG 50 and JPG 20. JPG 100 has the least compression and gives you a higher quality image while JPG 20 has the highest compression giving you the smallest file size but lowest quality as well.
