Will Plug in Speed conflict with other apps?
Rarely, developers implement hacky, non-standard code. This code can conflict with other apps. As with installing any app we recommend that you test before and after enabling Plug in Speed code optimizations to check everything works as it should.
In the unlikely case of a conflict we are available on email@example.com.
You should have only one app installed that optimizes your images. If you have more than one, your images will get stuck in a constant state of being optimized. That's a problem if either or both of the apps are using lossy image optimization: the quality of the images will continue to degrade over time.
Select one app that optimizes your images and stick with it.
