WP Smush.it

Reduce image file sizes and improve performance using the Smush.it API within WordPress.

Dear Smushers: WP Smush.it has found a new maintainer. Stay tuned for a fresh release.

Yahoo's excellent Exceptional Performance series recommends optimizing images in several lossless ways:

  • stripping meta data from JPEGs
  • optimizing JPEG compression
  • converting certain GIFs to indexed PNGs
  • stripping the un-used colours from indexed images

Smush.it offers an API that performs these optimizations (except for stripping JPEG meta data) automatically, and this plugin seamlessly integrates Smush.it with WordPress.

How does it work?

Every image you add to a page or post will be automatically run through Smush.it behind the scenes. You don’t have to do anything different.

Existing images

You can also run your existing images through Smush.it via the WordPress Media Library. Click on the Smush.it now! link for any image you'd like to smush.

As of version 1.4.0 there is a new, experimental Bulk Smush.it feature. You can find the link under the Media Library tab.

Errors

Sometimes the Smush.it service goes down or is under heavy load. If the plugin has difficulty connecting to Smush.it then automatically smushing is temporarily disabled (currently for 6 hours). You can always re-enable it via the Media > Settings screen or manually smush the image from the Media Library.

You can also define how long you want to wait for the Smush.it server to respond.
