Which file types are supported?

Most common media files are supported for optimization and delivery by Cloudinary. For free accounts, you will not be able to deliver PDF or ZIP files by default for security reasons. If this is a requirement, please contact our support team who can help activate this for you.

To deliver additional file types via Cloudinary, you can extend the functionality of the plugin using the actions and filters the plugin exposes for developers.

I have various other plugins installed, will the Cloudinary Plugin still work?

I’m having an incompatibility issue with a theme, plugin, or hosting environment, what can I do?

We’re compatible with most other plugins so we expect it to work absolutely fine. If you do have any issues, please contact our support team who will help resolve your issue.

Why are my images loading locally and not from Cloudinary?

Your images may be loading locally for a number of reasons:

  • The asset has been selected to be delivered from WordPress. You can update this for each asset via the WordPress Media Library.
  • Your asset is stored outside of your WordPress storage.
  • The asset is not properly synced with Cloudinary. You can find the sync status of your assets in the WordPress Media Library.

The plugin stopped sync after some time and doesn't sync after many tries

The plugin overwrites post content directly, will take out Youtube links and if the names of your photos are not unique, it will mix everything up. If you uploaded 1.jpg in June and a different 1.jpg in December, it will take them as a single picture. YOU WILL LOSE YOUR DATA
