This online JavaScript compressor can take your JavaScripts and automatically detect and remove unnecessary code you do not really need to display your web pages in the exact same manner. It also minifies unnecessary large JS scripts into smaller scripts.
By removing or minifying code in your scripts it reduces the script size. Having smaller sized JS scripts and files means your visitors can load your web pages faster because they need to download less data when loading your web pages.
Yes, click on the Upload and Compress tab and choose the JS file you want to compress. Click on the Select More Files link to upload more than one file. When you choose to upload and compress multiple JS files they will be combined into one bigger script. You can upload up to 10 JavaScript files at a time.
