From the developer
Jacob Allred's own description of CW Image Optimizer, lightly tidied.
The CW Image Optimizer is a WordPress plugin that will automatically and losslessly optimize your images as you upload them to your blog. It can also optimize the images that you have already uploaded in the past.
Because CW Image Optimizer uses lossless optimization techniques, your image quality will be exactly the same before and after the optimization. The only thing that will change is your file size.
The CW Image Optimizer plugin is based on the WP Smush.it plugin. Unlike the WP Smush.it plugin, your files won’t be uploaded to a third party when using CW Image Optimizer. Your files are optimized using the Linux littleutils image optimization tools (available for free). You don’t need to worry about the Smush.it privacy policy or terms of service because your images never leave your server.
Why use CW Image Optimizer?
- Your pages will load faster. Smaller image sizes means faster page loads. This will make your visitors happy, and can increase ad revenue.
- Faster backups. Smaller image sizes also means faster backups.
- Less bandwidth usage. Optimizing your images can save you hundreds of KB per image, which means significantly less bandwidth usage.
- Super fast. Because it runs on your own server, you don’t have to wait for a third party service to receive, process, and return your images. You can optimize hundreds of images in just a few minutes.
