Minification removes unnecessary characters and spaces from a file to reduce its total size, thus improving load times. When a WP file is minified, comments and unneeded white space characters (space, newline, and tab) are removed.
If you are using other Performance Plugins such as WP Rocket, SWIFT, or WP Fastest Cache, please be sure to either use their minification settings or ours, but avoid having multiple plugins perform the same optimization function as that can cause potential conflicts and site issues.
Combining CSS & JS can save data and speed up downloading, parsing, and execution time. However, if your site is on a server using HTTP/2 (most hosting servers are), then this may not be recommended due to the multi-threading capabilities in HTTP/2.
If you run into issues loading the Elementor Editor, try disabling ‘Combine JS’ and try again. You can enable this feature again once you are done editing with Elementor.
We recommend testing performance before and after enabling this feature to see which setting works best on your server environment.
