Description
Smooth CDN Connector connects WordPress media and selected site assets with Smooth Bundle, so you can deliver files through a managed CDN workflow while editors keep using WordPress as usual.
Use it when your WordPress site has a growing media library, repeated file traffic, client assets, downloadable files, or media that should be easier to manage, deliver, protect, and clean up.
From wp-admin, you can choose which files should sync to Smooth Bundle, serve synced files through CDN URLs, offload media from local storage, restore files when needed, and manage protected access for selected assets.
The plugin is focused on real WordPress files and assets: uploads, generated image sizes, selected Media Library files, and supported JS/CSS assets from active themes and plugins.
For REST API acceleration, use Smooth API Accelerator instead.
Useful for
- WordPress sites with growing media libraries
- Agencies and developers managing client websites
- Content-heavy sites that want a cleaner asset delivery workflow
- Projects that need CDN delivery without rebuilding the site
- Sites that want to offload selected media from local WordPress storage
- Teams that need protected delivery for selected files
- WordPress installations that want better control over synced and unused assets
Features
- CDN delivery for selected WordPress media and site assets
- Media Library based asset management directly in wp-admin
- Support for uploaded media files and generated image sizes
- Support for selected JS/CSS assets from active themes and plugins
- Manual and scheduled sync
- Automatic re-sync when attachments change
- URL rewriting for synced media and supported site assets
- Media offload with restore support
- Protected asset delivery with access management
- Unused assets view based on synced assets cross-checked against Smooth Bundle usage logs
- Controlled rollout, so assets can stay disabled, sync only, use rewritten URLs, or be offloaded
External services
This plugin connects to Smooth Bundle to authenticate the site, upload and delete synced media assets, manage protected asset access, fetch account and usage information, and optionally restore offloaded files from Smooth Bundle URLs.
When you connect the plugin, it sends your site domain to Smooth Bundle so the service can authenticate and prepare the connection.
When you sync media, it sends selected files and related asset metadata such as filenames, paths, hashes, protection settings, and project identifiers to Smooth Bundle so the assets can be uploaded, updated, delivered, and managed.
When you revoke, grant, or inspect protected asset access, it sends the relevant project identifiers, access identifiers, recipient email address, selected asset paths, and optional expiration date to Smooth Bundle to manage protected delivery.
When local offload restore is used, the plugin downloads the previously synced asset file from its Smooth Bundle delivery URL back to your WordPress uploads directory.
