This can be deployed on a per-side basis or network-wide for all sites. ### Does this convert images I’ve uploaded in the past? It does not convert images uploaded before installing this plugin. Changing image extensions and URLs after the fact can lead to issues where previously referenced images no longer work. If you use Cloudflare (even the Free plan), you can use Image Transformations to automatically convert legacy images to modern formats with the free [App for Cloudflare®](https://wordpress.org/plugins/app-for-cf/) plugin. ### I have an idea for this plugin, can I make a suggestion? Yes, please do!

Plus, it doesn’t display ads all over the admin interface to push for the CDN version. My only regret is that you can’t choose to keep a backup of the original image or remove the watermark. Maybe in a future update?
