A Guide to Website Image Basics


File Type

  • JPEGs and PNGs can be used, but JPEGs are the most common and highly recommended
  • File type can also depend on the purpose of the image
    • If the image is a logo or icon, a vector eps is required
    • If the image is for anything else like a banner image or thumbnail, a JPEG is the best file type

File Size and Resolution

  • The main idea here is that BIGGER is BETTER
    • A large scale, high resolution image is the easiest to work with
    • It is easier to reduce a large, high quality image than it is to make a smaller, lesser quality image larger
  • A rule of thumb is that the width should be no less than 2500 pixels wide
