BMP to GIF

This lesson is part of Web Developer Tools · All levels

Summary

BMP to GIF conversion reduces the file size by converting pixels to a maximum palette of 256 colors. Space savings can be huge, but fine-grained photos and gradations will lose detail and potentially appeal. GIFs remain useful for simple animations or older applications that do not support modern formats.

Key points

GIFs reduce the color to a maximum of 256 per frame
Appeals arise on gradations because of the limited palette
Dithering helps make the color transition look smoother
GIF transparency is only a bit.
Several BMP sequences can be combined into GIF animations
