Long time back I wrote a post on how you can optimize your images by reducing file sizes without compromising quality using Yahoo Smush.it tool. But do you really want to go that Yahoo page and upload and take the reduced image back to your blog every time when you upload a new photo in your WordPress blog? You would surely love something that can handle this process automatically when you upload a new photo to WordPress Media Library. More importantly what about your existing images that you have used in your previous posts? You are surely not going to take those pictures and upload in Yahoo Smush.it tool page and edit all those posts with these new pictures. Don’t worry, you don’t need to

Just install WP Smush.it WordPress plugin. There you will get option to Bulk Smush.it under Media tab in WordPress dashboard sidebar. By using that you can optimize all your existing images through Yahoo Smush.it API with only a few clicks. And when you upload a new image for your WordPress post, this plugin will automatically use Yahoo Smush.it API to reduce the file size and add it back to your blog post seamlessly. And you can go to Media > Library to see the stats of unnecessary bytes that have been removed from your image.

Hope that helps you to make your WordPress pages load a bit faster. It will help you in SEO as Google loves fast loading sites
