JavaScript Code Compressor

This tool compresses or minify JavaScript codes. It reduces the code size by removing the unnecessary data, such as extra spaces, line breaks, comments and indentation. It does not modify or recode the codes - it means that after the compression, the script will run perfectly just like the original algorithm.
