• Uncompressed

  • No reduction in file size

• Lossy Compression

  • Significant reduction size in file
  • Some data is permanently lost
  • Used for web
• Lossless Compression

  • Small reduction in file size
  • Data is exactly the same when uncompressed
  • Used for web and print
• PPI

  Measurement of pixel density
• .wav

  • no compression
  • many computers and audio players read it
  • big file sizes
  • not good for sharing music online
• .mp3

  • lossy compression
  • small file sizes
  • low audio quality
