Ever used an SEO tool to track and see how you can improve your website? A commonly requested fix on many of these engines is to “optimize images” for the web. The team at Slocum Themes uses a few different tools to optimizes images on WordPress. Read below to find out what technology to use to optimize images before, during, and after a WordPress upload.
Optimize Images on WordPress while uploading
Let’s start with talking about optimizing images as they are uploading. A free plugin that can used to optimize the images is called WP Smush.it from WPMU dev. This plugin will automatically optimize images as they are uploaded to the media library.
Please be aware of one drawback to WP Smush.it. If your image is over 1mb in size, the Yahoo! tool used in conjunction with WP Smush.it will not work. Any images over 1mb in size will not be optimized.
Optimize Images Already on WordPress
This limit applies to optimizing images that have already been uploaded to your server from the past. We also recommend WP Smush.it for this purpose since it is also as simple as one button. With the plugin installed, highlight “Media” on the left sidebar and there will be a new subheading for Bulk Smush.it. All you need to do is process all of your images from this page and you are all set and optimized.
Notice on the below image that all images are reduced and tell you what percentage in reduction that they have!
Please note that this process may take a few minutes, so get up from your computer and stretch or do something else for a couple of minutes while all of your old images get processed.

Optimize Images for web before uploading to WordPress
For crafty Mac users who want a great tool to optimize images before taking them into WordPress, the best free software to optimize images is ImageOptim. ImageOptim allows you to simply drag and drop photos or folders from your hard drive right into optimization software.
There are no settings to push or change on your end. ImageOptim does the work for you. It also replaces the original image with the optimized copy and places the original version of the image in the trash. VERY COOL!

WP Smush.it and ImageOptim are nice lossless compressors, but they don’t reduce file size enough. Even though I’ve trained them not to, many clients upload 7 MB photos straight into WordPress. I needed something more aggressive, and I found the Imsanity plugin. It automatically resizes and compresses uploaded images, greatly reducing file size. I wrote a post about using it: Imsanity plugin automatically resizes, compresses images. You may find it helpful too.

While I don’t have direct experience using Smush.it -I do frequently send this article out to people who ask me about ways to manage images.
