Object Eraser

Remove unwanted objects from images using AI inpainting (LaMa model). Accepts an image and a mask indicating the region to erase.

API Endpoint

POST /api/v1/tools/erase-object

Processing: Asynchronous (returns 202, poll /api/v1/jobs/{jobId}/progress for status via SSE)

Model bundle: object-eraser-colorize (1-2 GB)

Parameters

Parameter	Type	Required	Default	Description
file	file	Yes	-	Source image file (multipart)
mask	file	Yes	-	Mask image (white = area to erase, black = keep). Must be uploaded with fieldname mask
format	string	No	"auto"	Output format: auto, png, jpg, jpeg, webp, tiff, gif, avif, heic, heif, jxl
quality	integer	No	95	Output quality (1-100)

Notes

• Requires the object-eraser-colorize model bundle to be installed (1-2 GB).
• The mask must be the same dimensions as the source image. White pixels indicate areas to erase; the AI fills them with plausible content.
• Uses LaMa (Large Mask Inpainting) for high-quality object removal.
• For non-browser-previewable output formats, a WebP preview is generated alongside the main output.
• Supports HEIC/HEIF, RAW, TGA, PSD, EXR, and HDR input formats via automatic decoding.
