How to prepare an animated GIF for MMS via txtAgif

Hello class, today we are going to learn how to resize an animated GIF that you have downloaded from the web so that it can be uploaded to txtAgif.com ready for MMS by the world! txtAgif only accepts animated GIF file up to 100 KB with a maximum resolution of 160x120.

1. Get the free open-source program Gifsicle (supports Windows, Mac, Linux).
2. Open a command prompt window. 
3. Execute this command to resize and optimize your GIF:
• If your GIF's width is longer than its height: gifsicle -O2 -k100 -V --resize 160x_ path-to-your-gif-file.gif > new-gif-file.gif
• If your GIF's height is longer than its width: gifsicle -O2 -k100 -V --resize _x120 path-to-your-gif-file.gif > new-gif-file.gif 
• If there's no need to resize: gifsicle -O2 -k100 -V path-to-your-gif-file.gif > new-gif-file.gif
4. If the new optimized GIF file is still larger than 100 KB, you can decrease the number of colors by reducing the k parameter value. E.g. gifsicle -O2 -k50 -V path-to-your-gif-file.gif > new-gif-file.gif
5. Upload the new optimized GIF to txtAgif.com.

Gifsicle is a very powerful free software to edit your animated GIF file. You can learn more here.
