Unlimited media CDN for WordPress. Serve images, video, audio, and HLS streams from 300+ global edge servers.

Heavy media files slow down your WordPress site. When videos buffer and images lag, visitors leave, Core Web Vitals fail, and Google ranks you lower.

Unlimited CDN delivers all your media through Cloudflare's global edge network. No DNS changes. No external accounts. No configuration. Images, videos, audio files, and HLS streams load from the nearest server to each visitor.

Safe to try on any site. Does not touch your database or existing files. Disable at any time and your site instantly returns to normal. If Cloudflare ever has an issue, WordPress automatically loads your original media.

1. You upload media to WordPress as usual
2. The plugin rewrites media URLs on your frontend pages
3. When a visitor requests media, a Cloudflare Worker fetches it from your site and caches it in R2
4. Future requests serve cached media from Cloudflare's edge (300+ locations worldwide)

Your original files stay on your server. WordPress keeps full control. The plugin only changes how media is delivered to visitors.

One-click setup. We handle the Cloudflare infrastructure.

7-day money-back guarantee. Cancel anytime.

For developers who want full control. Deploy the open-source worker on your own Cloudflare account.

• Your media, your infrastructure
• Zero external dependencies

The plugin intercepts the final HTML output and rewrites media URLs:

Before: https://yoursite.com/wp-content/uploads/2024/01/video.mp4
After:  https://cdn.img.pro/yoursite.com/wp-content/uploads/2024/01/video.mp4

Rewriting happens at render time. Database URLs remain unchanged.

Video and audio files support HTTP range requests for:

• Seeking to any position without downloading the entire file
• Resumable downloads
• Efficient bandwidth usage

M3U8 playlists are served with correct MIME types. TS segments are cached at the edge for low-latency adaptive streaming.

• Media is cached on first request
• Cache persists until explicitly purged
• Stale-while-revalidate for uninterrupted delivery
• Automatic fallback to origin if cache unavailable

Usage is tracked by request count (not bandwidth). View analytics in Settings > Unlimited CDN.
