Technical Specifications for Images

  • Resolution - The resolution of am image determines the quality and clarity. A high-resolution photo contains more pixels per inch (ppi) to provide a clearer image. High-resolution photos (300+ ppi) are used for printing and large format uses. Images for digital use don't need as high of a resolution so 72 ppi should be appropriate as it keeps the file size more manageable for websites and web servers. The higher the resolution, the larger the file size. The lower the resolution, the smaller the file size. 
  • Size - When an image or graphic is created, the creator determines a canvas size. This determines the original size of the image (in pixels) that can be scaled proportionately to be larger or smaller.
  • Format - Images can be saved into various image formats or file types. Image software tends to allow conversion of one format to another. Below are a few of the most common:
    • JPEG (.jpg): Many images are stored as JPEG files because this format allows files to be compressed to take up less space. Because JPEG files are small, they are easily transported (email, flashdrives, etc).
    • GIF (Graphics Interchange Format, .gif): Another popular file type found on the web. GIF images are widely used for graphics and multiple images can be saved as one GIF to show movement as a rotation of still images.
    • TIFF (Tagged Image File Format, .tif): saves an uncompressed digital reproduction. Therefore, it is recommended you originally save high-quality TIFFs and then create JPEGs for general use.
    • BMP: uncompressed proprietary Microsoft format.
    • Other formats include, but are not limited to: PSD (Photo Shop Document), SVG, and RAW
