|JPG||best for photographs and screenshots. Use JPG when small file size is more important than high image quality (e.g. screen display). JPG can be used for printed materials but should be saved at a (higher) print quality than files for screen use only||
|PNG||best for logos, clip art, and graphics with solid areas of colour. Not used for photos or graphics with gradients and many colours. PNG is a lossless, small file size format good for screen display. It supports transparent backgrounds. PNG was developed to replace GIF.|
|GIF||Can be used in the same place as PNG. GIFs are small file size, low resolution images used on websites. This format support transparent backgrounds and is also used for short animations. LibGuides does not support animated GIFS but you can use still GIFS (similar to PNGs)|
|TIFF||best for photographs and graphic design elements that need to be high quality. TIFF is a lossless format and is often used for professional work in programs like Photoshop and InDesign. TIFFs are usually very large files and are used for high quality printed materials, do not use for web graphics.||TIFF files cannot be displayed on websites.|
