If you are generating images for use on web sites, convert at 72 dpi (dots per inch) or 96 dpi. These settings match screen resolution pixel for pixel for the best match and sharpest display. For general office printing, choose 150 dpi. This will generate a crisp image with the smallest file size. For office publishing and high quality laser printing, choose 300 dpi. The files will be larger but the images will be very clear. For professional printing, choose 300 dpi - 1200 dpi. It's best to ask your printer who will recommend the best resolution to match his equipment.
