Runflow Background Removal API
What Runflow Background Removal API is
Runflow Background Removal API is a paid endpoint for turning images into transparent PNG cutouts. It accepts JPEG, PNG, and WebP files or image URLs through an HTTP POST request using a Bearer API key. Inputs can be up to 4096×4096 pixels, and the returned PNG includes a full alpha channel. Requests may also include a mask or solid-color replacement, although replacement backgrounds are not a standard output feature. Runflow combines coarse subject detection with sub-pixel alpha matting to preserve hair, fur, transparent objects, and fine fabric edges. The service is designed for product, people, animal, and food imagery. Batch endpoints and asynchronous webhooks support bulk jobs, while processing typically takes under three seconds per image. A live image test is available without signup. Pricing starts at $0.05, with no free API plan.
