Resize your images before they are uploaded to your website (server), no need to use image editing software. Drag+drop images from your digital camera to WordPress. This plugin works best in HTML5 compatible web browsers such as Chrome or Firefox.
If your web browser does not support HTML5 then this plugin will swap your image uploader runtime to the Adobe Flash version which makes sure the resize function works across more web browsers. The side effect to this is drag+drop will be disabled since this is not supported in Flash (everything works in HTML5 compatible browsers). If you experience issues or drag+drop is more important to you than resizing images then you can disable the Flash override in your settings -> media.
This plugin does not work on the iPhone or iPad.

Upon searching the WordPress repository, it’s clear that every plugin that resizes images for you is a paid service, with one exception, THIS plugin! By resizing the imaegs on our website, we’ve been able to drastically reduce traffic and server load. The benefits become even more apparent as we continue to grow. Thanks for this brilliant plugin!
I had big problems with my host, uploading bigger images.
This plugin really save my time!
First of all, thank you dear devs. Undoubtedly a great work.I must admit that using and maintaining a shared hosting for a high traffic website is tricky. And if compressing image takes 100% CPU and I/O usage, then its a hectic job. Used almost all other plugs but all of them exhausted my server. But as this one uses resource from client side so image compression has become faster and more stable from a server resource point of view.
this is awesome.
Simple to use, works out of the box. Thank you.
