JPEG vs PNG vs GIF

Just a note to remind myself:

• JPEG:
  • Good:
    • Photographs
    • Game screenshots
    • Movie stills
    • Desktop backgrounds
  • Bad:
    • Windows application screenshots
    • Line art and text
    • Comic strips
    • Anywhere where fine lines or sharp color contrast is needed
• PNG:
  • Good:
    • Text, line art, comic-style drawings, general web graphics
    • Windows application screenshots
    • When accurate reproduction (lossless) is required (24 bit PNG)
    • When alpha channel support is required
    • As a general replacement for anything that is a non-animated GIF
  • Bad:
    • Photos, in-game screenshots (only when quality is not important and you're looking for small files)
    • Disappointing browser support for 32 bit PNGs from Microsoft and others
• GIF:
• Good:
  • Where animations are required
  • Widespread browser support
• Bad:
• Large file sizes compared to PNG for the same quality
• Often limited to 256 colors (8 bit)

Thank you, random website.
