PNG or JPG?
PNG is lossless, so text, lines and charts stay perfectly sharp with no blurry edges. It is the better choice for pages that are mostly text or graphics. JPG makes smaller files and is better for pages that are mainly photos.
150 DPI is good for viewing on screen. Use 300 DPI if you want to print the images or zoom in on small text, but expect bigger files.
