CloudFlare URL Replacement

This plugin will help you replace link to the CloudFlare server.

Freemius

Wrenio

Move your WordPress media library to Cloudflare R2 — and serve every attachment from R2 (or a custom domain mapped to your bucket) without changing how WordPress works elsewhere.
What it does
<ul>
<li>Uploads new media to R2 as attachments are added (via scheduled background sync).</li>
<li>Uploads existing media in batches via the Bulk Sync page.</li>
<li>Rewrites attachment, <code>srcset</code>, and in-content image URLs to the R2 (or CDN) origin.</li>
<li>Optionally deletes the local file after a successful upload to save disk inodes.</li>
<li>Fills in thumbnail metadata for attachments whose local file has been deleted.</li>
<li>Reconciles R2 object keys with local paths if they have drifted.</li>
<li>Repairs filename-level mismatches between WordPress and R2.</li>
<li>Identifies orphan R2 objects that are no longer referenced by any attachment.</li>
</ul>
Credentials
Credentials can be stored in the database via the settings page, or — recommended — defined as constants in <code>wp-config.php</code>:
<pre><code>define( 'WRENIO_R2_ACCOUNT_ID', 'your-account-id' );
define( 'WRENIO_R2_ACCESS_KEY_ID', 'your-access-key' );
define( 'WRENIO_R2_SECRET_ACCESS_KEY', 'your-secret-key' );
define( 'WRENIO_R2_BUCKET_NAME', 'your-bucket-name' );
define( 'WRENIO_R2_PUBLIC_URL', 'https://media.example.com' );
</code></pre>
Constants take priority over values stored in the database.
The reconciliation tool
R2 object keys are derived from the stable <code>_wp_attached_file</code> meta. If keys drift away from an attachment’s physical file path — for example, due to external tooling or imported content — the Reconcile page detects the drift and previews the realignment plan.
Run Wrenio Media Offload → R2 Reconcile → “Start Dry Run” to scan and preview a fix plan. (Live realignment that moves R2 objects to their correct keys is available in the Pro version — see below.)
Cleanup tools
<ul>
<li>Filename Cleanup detects attachments where the filename portion of <code>_wp_attached_file</code> differs from the R2 key (typically caused by double-dot or similar normalization mismatches) and repairs the WordPress meta to align with R2.</li>
<li>Orphan Cleanup walks the bucket via ListObjectsV2, builds the set of keys referenced in post meta, and offers a reviewable list of R2 objects that aren’t referenced anywhere. Deletion is opt-in per batch.</li>
</ul>
Pro version
A Pro version is available at https://wrenio.studio/ for users who need the destructive operations: live R2 reconciliation (moving drifted objects to their correct keys), orphan deletion (removing unreferenced R2 objects), and retry counter resets.
<h3>External Services</h3>
This plugin connects to the following external services. They are listed here so you know what data leaves your site and when.
Cloudflare R2 — required for the plugin to function.
You configure your own Cloudflare R2 credentials. The plugin uses them to upload, download, list, and delete objects in your bucket — only the bucket(s) you specify. No request is ever made to Cloudflare without your credentials, and the credentials never leave your server.
<ul>
<li>What is sent: the media files you upload to WordPress, plus the API requests needed to manage those files in R2.</li>
<li>When: on attachment upload, during bulk sync, and during reconciliation or orphan-cleanup runs you initiate.</li>
<li>Cloudflare terms of service: https://www.cloudflare.com/terms/</li>
<li>Cloudflare privacy policy: https://www.cloudflare.com/privacypolicy/</li>
</ul>
Freemius — used for plugin updates and Pro licensing.
This plugin uses the Freemius SDK to deliver plugin updates and (if you purchase a Pro license) to validate that license. By default, Freemius collects nothing from your site without your explicit opt-in. If you opt in at activation, anonymous usage statistics are shared to help improve the plugin; you can opt out at any time from the plugin’s Account page.
<ul>
<li>What is sent: only what you opt into when you first activate the plugin (or nothing at all if you skip the opt-in). When activating a Pro license, the license key is sent to Freemius for verification.</li>
<li>When: at activation (one-time prompt), when a Pro license is activated or deactivated, and during update checks.</li>
<li>Freemius terms of service: https://freemius.com/terms/</li>
