Cloudflare Images - Transformation flows in Images
Key Points
- Automated image transformations
- Provider flows support Fastly
- Custom flows include width=auto
Summary
Cloudflare Images now supports Transformation Flows: rule-based automation that applies image optimizations at the zone level without changing client URLs or adding code. Flows evaluate request conditions (file extension, path, query params, etc.) and apply parameterized actions automatically.
Key Points
- Two flow modes:
- Provider flows: migrate from another optimizer (currently supports Fastly Image Optimizer). Cloudflare rewrites provider-specific parameters to Cloudflare equivalents so existing URLs keep working.
- Custom flows: define conditions and actions for use cases like automatic format conversion, responsive sizing (width=auto), and directory-based optimization.
- Flows operate at the Images > Transformations > Automation page in the Cloudflare dashboard.
- Use flows to centralize image optimization policy per zone without code or URL changes; good for migration and consistent, automated optimizations.
