Exact numbers are shown on Account → Subscription and the public pricing page.
How a job runs
- 1
Upload an image in WordPress
With cloud image optimization enabled and API keys connected, the plugin queues a job.
- 2
Cache Rocket processes the file
The image may be resized and encoded to WebP and/or AVIF according to your entitlements.
- 3
Stored and rewritten
The result is stored for Managed CDN delivery. When ready, front-end markup points at
assets.cacherocket.com.
Quotas hard-stop new work
When the monthly image-optimization quota or CDN bandwidth is exhausted, new jobs do not start until the period resets or you upgrade.

Common questions
- Will it rewrite my whole media library overnight?
- No. Optimization targets new uploads when enabled. Existing attachments are not bulk-migrated automatically.
- What if AVIF is not in my plan?
- WebP still applies on Starter+. Upgrade to Pro or Business for AVIF preference.
- Does disabling the feature delete CDN files?
- Yes. Disabling cloud image optimization removes that site’s related optimized objects from Managed CDN storage.
