A .htaccess file is a configuration file for Apache web servers that allows you to control various aspects of your website including URL rewrites, security settings, redirects, and caching without modifying server configuration files.

Select the options you need from the available categories (security, performance, URL rewriting, etc.), customize the settings, and the tool will generate the appropriate htaccess rules that you can copy and use.

Place the .htaccess file in the root directory of your website on your Apache server. Make sure Apache is configured to read .htaccess files (AllowOverride setting).
