How does the background removal API generate transparent PNGs?

The background removal API uses AI to detect the foreground subject and remove the background, producing a clean PNG with an alpha transparency channel. It handles complex edges like hair, fur, and semi-transparent objects for professional-quality cutouts.

Can I replace the background instead of removing it?

Yes. In addition to transparent background removal, the API offers dedicated endpoints to blur the background, replace it with a solid color (RGBA), or apply a vertical gradient. Each effect endpoint returns a processed PNG via a CDN URL.

What image formats and sizes does the background removal API support?

The API accepts JPEG, PNG, WebP, BMP, and TIFF images up to 10 MB. You can upload a file via multipart/form-data or pass a public image URL via JSON. Output is always a high-quality PNG delivered through a CDN link.
