JSMin - JS Compression

JSMin is a filter which removes comments and unnecessary whitespace from JavaScript files. It typically reduces filesize by half, resulting in faster downloads. It also encourages a more expressive programming style because it eliminates the download cost of clean, literate self-documentation.

ShrinkSafe - JS Compression

ShrinkSafe is a JavaScript "compression" system. It can typically reduce the size of your scripts by a third or more, depending on your programming style.

Many other tools also shrink JavaScript files, but ShrinkSafe is different. Instead of relying on brittle regular expressions, ShrinkSafe is based on Rhino, a JavaScript interpreter. This allows ShrinkSafe to transform the source of a file with much more confidence that the resulting script will function identically to the file you uploaded.
