Using the S3 PHP SDK
The Advanced Media Offloader utilizes the AWS SDK for PHP to interact with S3-compatible cloud storage. This powerful SDK provides an easy-to-use API for managing your cloud storage operations, including file uploads, downloads, and more. The SDK is maintained by Amazon Web Services, ensuring high compatibility and performance with S3 services.

-
Does this plugin support other cloud storage platforms?
-
Currently supports Cloudflare R2, DigitalOcean Spaces, Amazon S3, Wasabi & MinIO. Additional providers are on the roadmap based on user demand.
-
What happens to the media files already uploaded on my server?
-
Existing files remain untouched until you explicitly use the bulk offload feature. New uploads are automatically processed based on your settings.
-
How exactly does URL rewriting work?
-
The plugin hooks into WordPress core media functions using
wp_get_attachment_urland related filters. This ensures compatibility with themes, plugins, and core functions without modifying database URLs. -
Can I rollback if needed?
-
Files offloaded with “Retain Local Files” can be served locally by deactivating the plugin. For full cloud migrations, you’ll need to re-download media files if you want to revert.
-
How are image sizes and thumbnails handled?
-
All generated image sizes are offloaded alongside the original. URL rewriting works for all sizes and srcset attributes.
-
Will this work with page builders and media-heavy plugins?
-
Yes, since the plugin uses WordPress core hooks for URL rewriting, it’s compatible with Elementor, Beaver Builder, WooCommerce, and most other plugins that use standard WordPress media functions.
-
Does it support private files with access control?
-
The free version only supports publicly accessible files. Private files with authenticated access may be added in a future premium version.
-
What happens if I remove a media file from the WordPress Media Library?
-
With “Mirror Delete” enabled, corresponding cloud files are automatically removed. Otherwise, files remain in cloud storage, potentially creating orphaned objects.
-
How can I debug issues with file offloading?
-
The plugin logs errors to attachment metadata. Check the Media Overview page for detailed error reporting or enable WordPress debug logging for more information.
-
What’s the recommended bucket configuration?
-
For optimal performance:
1. Enable CORS configuration
2. Set appropriate public read permissions
3. Configure proper region (closest to your audience)
4. Consider using a CDN for global distributions
