Limitations

Resizer processes two types of requests: cached and non-cached.

Cached requests

Cached requests are served directly from Cloudflare's global CDN with no rate limits.

• For more details on the caching, refer to Cloudflare's Tiered Cache documentation.

Non-cached requests

Non-cached requests are rate limited.

• Limited to 60 requests per minute per IP.
• If the limit is exceeded, a 429 (Too Many Requests) error will be returned.

You can retry the request after a few minutes.

General Restrictions

• Maximum file size for an input image is 50MB.
