WebWrap is a small 3-in-1 utility program to compress and/or code your HTML web files. It uses either a modified LZSS algorithm or the URL encryption procedure, and can reduce the size of your files by more than 50%. It also renders the source of any HTML pages you have created, your design features and your scripts for example, inaccessible to easy viewing or simple clip and paste procedures. The “WebWrapped” files you create are self-extracting and do not require any third-party software. In addition to compressing and coding your HTML files, you also have the opportunity to add automatically a password protection script.
