Image

Transforms, overlays, and async bg-remove on one image API

URL delivery transforms, project-scoped watermarks, Studio pipelines, and async background remove — all hard-scoped to organization and project.

What you get

URL transforms & overlays

Resize, format, effects, and text or image watermarks on delivery URLs. Overlays stay within the same project.

Studio pipelines

Multi-step image operations including watermark — run as async jobs. Save as a new asset or variant.

Async background remove

Queue background remove as a project-scoped job. Returns a new PNG or WebP with alpha for delivery and further transforms.

Job Center lineage

Track every image job in the portal Job Center. Outputs stay in the same project and folder.

Included

  • Same-project overlays
  • Flexible watermark placement
  • Async background remove
  • Signed delivery

Differentiation

Image platform depth

  • Hosted and pull URL transforms
  • Project watermark profiles and overlays
  • Studio pipeline watermarks
  • Async background remove
  • Unified Job Center for image and video
  • Tenant-isolated storage
  • Signed delivery URLs
  • Named transform profiles

Example

Same auth and tenancy headers as the rest of the API. Where a capability plugs into Flows today, that is called out on the product page — we do not imply every media type shares one live pipeline yet.

POST /v1/images/{id}/bg-remove

{
  "format": "png"
}
// 202 → background-remove job
// result includes the new asset id when complete
