Bria Remove Background

Playground

Bria AI’s remove background model.

Features

Bria Remove Background

Bria Remove Background extracts clean subjects from images with a high-quality alpha matte. It’s fast, consistent, and production-ready for e-commerce listings, ad creatives, social posts, and compositing. The model is trained on licensed data, supporting safe, compliant commercial use.

Highlights

Clean cutouts with detailed edges (hair, fur, semi-transparent areas).
Alpha workflow: preserve or drop the alpha channel to match your pipeline.

Parameters

image* (required) Source image (URL or upload). Missing image will fail.
preserve_alpha (checkbox) Keep the alpha channel in the returned asset for immediate compositing.

Pricing

Per run: $0.018

How to Use

Upload/Paste image (required).
Toggle preserve_alpha if you need a premultiplied cutout for direct compositing.
Click Run to generate your cutout and download the result.

Output & Workflow Tips

Post background: Place the cutout over solid color, gradient, or generated scenes (e.g., with Bria Background Generation).
Edge finesse: For extremely fine hair or translucent fabric, a light feather/refine-edge pass can achieve pixel-perfect results.
Consistent catalogs: Use identical lighting shots and batch the same settings for uniform store pages.
