Bria Eraser

Playground

SOTA Object removal enables the precise removal of unwanted objects from images while maintaining high-quality outputs. Trained exclusively on licensed data for safe and risk-free commercial use

Features

Bria Eraser

Bria Eraser removes selected regions from an image using a mask, then inpaints the missing areas with context-aware detail that matches lighting, perspective, and texture. Trained on licensed data for compliant commercial use across ads, product shots, portraits, and scene cleanup.

✨ Highlights

Precise control with masks — erase exactly what you mark; keep everything else untouched.
Context-aware fill — realistic inpainting that blends edges, light, and color.
Alpha-friendly pipeline — preserve transparency for instant compositing.
Flexible delivery — sync or async API, URL or BASE64 outputs.

🧩 Parameters (1:1 with the panel)

image* (required) Source image (URL or upload).
mask_image* (required) black = keep, white = move

🚀 How to Use

Upload/Paste image (required).
Upload/Paste mask_image (required). White regions will be removed and inpainted.
(Optional) Toggle preserve_alpha if you need transparent output for compositing.
Click Run to generate and download your cleaned image.

💰 Pricing

Per run: $0.04

🧠 Practical Tips

Mask quality matters: use soft brushes at edges (5–15 px feather) to avoid seams.
Iterate fast: keep settings, adjust only the mask for rapid alternatives.
Compositing: with preserve_alpha, drop directly over new backgrounds or graded plates.

Task Submission Parameters

Request Parameters

Parameter	Type	Required	Default	Range	Description
image	string	Yes		-	The URL of the image to erase.
mask_image	string	Yes		-	The URL of the mask image to generate an image from.
preserve_alpha	boolean	No	true	-	Preserve alpha channel in output
enable_sync_mode	boolean	No	false	-	If set to true, the function will wait for the result to be generated and uploaded before returning the response. It allows you to get the result directly in the response. This property is only available through the API.
enable_base64_output	boolean	No	false	-	If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.
