Frequently Asked Questions

Common questions about IOO - Image Offload & Optimize

Yes. Image conversion runs on hosted servers, so no image conversion software is required on your WordPress host.

New uploads are offloaded automatically. Existing images can be offloaded using the bulk migration tool in the plugin admin.

No. Your local files are left in place. The plugin sends the image's URL to the hosted service, which fetches and converts it and stores the result; your image URLs are then rewritten to serve from the CDN. Nothing is removed from your server. On paid plans your original image is also backed up to the hosted service.

Yes. All core image blocks are supported — core/image, core/gallery, core/media-text, and core/cover. URLs in blocks are rewritten for CDN delivery.

WooCommerce product images use standard WordPress attachments and are handled by the same URL rewriting.

If an image has not been offloaded, or offloading failed, the original local URL is used. Once an image is offloaded, the picture markup serves AVIF where supported and WebP otherwise, both from the CDN. This does not guarantee delivery during a service or CDN outage.

Your API key is stored in the WordPress database and is sent to the hosted service to authenticate API requests. Protect access to your WordPress admin and database.

The offloaded copy is not updated automatically. Editing an image in the WordPress image editor, or regenerating thumbnails, changes the local files only. To refresh the hosted copy, delete the attachment and upload it again.
