# Bulk compressing

 * After finding out in another topic that it’s a good idea to have just one plugin
   compressing my images, I decided to choose WP-optimize for that purpose, especially
   becuase of the WebP conversion it provides.
 * I compressed a few images manually and that seems to work fine, but since I have
   over 3000 images, I’d like to do the rest in bulk.
 * However, under “uncompressed images”, there’s just one image. That may have to
   do with the fact that the other images were compressed before by another plugin,
   Smush. But I deactivated Smush and I clicked “mark all images as uncompressed”
   and still no images show up.
 * Is there a way to make the bulk edit work?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fbulk-compressing%2F%3Foutput_format%3Dmd&locale=en_US)

 * WebP conversion won’t work for already uploaded and compressed images. To use
   WebP on existing images, you will need to restore the original images and compress
   them again

 * I manually compressed a few dozen images, simply by going to each of them in 
   the media library and clicking compress. WP-optimize compresses them even a little
   bit more, even though they were already compressed by Smush. And WebP-versions
   are created as well.
 * So for some reason, in my case, WebP conversion does work on images that were
   previously compressed. It’s a pity the ones that still have to be done don’t 
   show up in the bulk editor. Because manually compressing almost 3000 images, 
   that’s a lot of work…
 * (and unfortunately restoring the original images is not an option)
