Upload files to your R2 bucket, browse stored objects, and generate expiring signed download links — all from your WordPress dashboard. Unlike traditional storage solutions, this plugin ensures that your files remain private and are only accessible through controlled, time-limited URLs. ### Key Features (Lite) * **Secure Document Sync** – Synchronize documents and digital assets from WordPress to Cloudflare R2 without altering frontend media URLs. * **Direct Upload to R2** – Securely upload files from WordPress to Cloudflare R2. * **Secure Downloads via REST API** – Generate expiring signed URLs using a hardened REST endpoint. * **Private File Delivery** – Files are not publicly accessible and are delivered via signed URLs. * **Configurable Expiration** – Set custom expiration times for download links. * **Basic File Browser** – View and manage stored files from the admin panel. * **S3-Compatible API** – Fully compatible with Cloudflare R2 infrastructure. ### Use Cases * Deliver private digital files securely * Share time-limited download links * Protect premium content * Replace insecure direct file URLs * Manage external storage for documents and digital assets ### Pro Version (Optional) Upgrade to unlock advanced capabilities: * High-capacity multipart uploads for very large files * Drag & drop interface * Advanced file manager with folders * Download tracking & analytics * User quotas and restrictions * Advanced security (IP, referer, geo restrictions) * Webhooks & automation tools More information: https://www.r2suites.com/products/wordpress/cloudflare-r2-storage- manager-pro ### Architectural Policy & Limitations **CR2SM Lite is a Secure File Sync tool for documents, zip files, and digital products. It is NOT an image CDN or frontend acceleration plugin.** To guarantee architectural stability and prevent unexpected CDN abuse, this plugin enforces a strict **No-URL-Rewrite Policy**: * It MUST NOT filter `wp_get_attachment_url`.* It MUST NOT rewrite `srcset` attributes. * It MUST NOT replace native attachment URLs on your frontend. * It MUST NOT alter frontend delivery or inject CDN URLs. This plugin is exclusively designed for secure backend synchronization of documents and digital assets. ### External Services This plugin connects to Cloudflare R2 Object Storage.
