The Unzipper is a PHP script that can extract ZIP and GZIP archives on webservers. All you need to do is upload a PHP file and access the file from your web browser.
The Unzipper will only list any ZIP/GZIP files that are located in the same directory as the PHP script in the drop down menu. So if you don’t see the archive file that you want to extract, double check the location of the unzipper PHP script and the ZIP/GZIP file.
