GIFmation

GIFmation is an image creation and editing tool that lets you construct animated GIF files. GIFmation has an extensive feature set to give you the ability to easily create highly optimized GIF animations for your Web pages. No other tool makes GIF animation as easy.

Its features include complete control of the color reduction process (such as palette usage, bit depth, and the amount of dithering), custom local or global palettes for each file, and the ability to readjust bit depths to lower levels as needed. GIFmation also provides automatic browser compatibility checking to ensure that your animated GIF files can be viewed by any browser that supports them. This demo version will allow you to create animated GIFs of no more than three frames in length.
