Unity Anim Size Compressor
A handy animation file compressor.It considerably reduces Unity's .anim file size.
1.Drag the animation folder which contains all .anim files into the "Animation Folder" field.
2.Choose a quality.The default value is "High",which would yield best result and biggest size.The lower the quality is,the smaller the file size would be.
3.Click "Compress" button.
It may take dozens of seconds for the program to process the compression.Once done,there will be some new .anim files appearing in the same folder.The "_h","_m" and "_l" suffixs represent high,medium and low quality individually.
