Works very fine

Many thanks for this great plugin, it saved me so much time! Easy to use and bulk conversion worked perfect. My favorit image quality to file size ratio on photos was 75 % JPG quality.

Works perfect!

I really like this plugin. Set and forget! Limited options in the free version, but most of the time this is perfect.

5 star because we cannot give more

Awesome plugin, directly goes to my default install list ! Thank you for the great work !

by Jason L

Was 5 star, now broken. Back to 1.2.0

used to work perfectly. I wish I could find older versions, as 1.2.2 no longer automatically converts images when uploaded. never should have updated. so annoying, and now looking for a new solution.
