  1. Common Bitmap Image File Types File Size vs. Image Quality

  2. JPEG, JPE, JPG • Best for full-color photographs • Highly compressed • Encoded in full color • Lossy compression • Loses quality as you edit and save • JPG most universally used lossy format

  3. GIF • Good for fewer colors, such as a logo • Indexed format – uses up to 256 colors • 256 = 28 referred to as 8-bit color • Advantages • Transparency • Animation

  4. PNG • Two modes • Indexed • Full color • Lossless compression • Full and partial transparency • Doesn’t support animation

  5. XCF • GIMP native format • Saves layers and other information

  6. TIFF, TIF • Full-color • Non-lossy & lossless • Various “dialects” of TIFF • Good for keeping originals

  7. RAW • Proprietary camera formats • BMP • Windows format; huge files; no advantage over PNG or TIFF • PSD • Adobe’s proprietary format • ICO • Windows Icon format
