When and how to use internet image formats
Posted on March 14th, 2006 by Chris Heath
What is this guide for? To teach you how to use the correct image formats for the correct situation. I am personally fed up of seeing people use gif for photos, jpeg for Windows screencaps, and other totally inappropriate image format uses. So I made this guide in an attempt to explain how and when to use what formats.
THE SUMMARY:
- JPEG:
- Good:
- Photographs
- Game screenshots
- Movie stills
- Desktop backgrounds
- Bad:
- Windows application screenshots
- Line art and text
- 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 absolutely 100% quality is required (24 bit)
- 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 from Microsoft and others
- GIF:
- Good:
- Where animations are absolutely required
- Widespread browser support
- Bad:
- Patented, legal techicalities
- Large file sizes compared to PNG for the same quality
- Obsolete
