Standard Usage
Black-and-white mask: white is erased, black is kept; must match the image's aspect ratio. Paint slightly beyond the object edge
Manual for brush-drawn masks; automatic for masks from a segmentation tool
Keep transparent areas transparent when the input has an alpha channel
Ready for generation
Configure your parameters and click "Run" to see the output here.
Each case shows the image, the black-and-white mask and the full erased result side by side — no prompt involved, with zoom for the filled-in background.
1 source image + mask / 1360 × 768
Remove peopleInput: a quiet cobblestone street with one passer-by walking in the middle. Mask: the person. Output: the person is removed and the cobblestones, walls and light are filled in naturally.
1 source image + mask / 1360 × 768
Clean up clutterInput: a white mug on a wooden table with a crumpled paper ball and a used tea bag beside it. Mask: the paper ball and the tea bag. Output: a clean tabletop with only the mug, wood grain continued.
1 source image + mask / 1360 × 768
Interior clean-upInput: a minimal living room with a wooden sideboard and a black cable running down the wall into a socket. Mask: the cable and the socket. Output: a clean, uninterrupted wall above the sideboard.
1 source image + mask / 1024 × 1024
Keep transparencyInput: a transparent-background PNG of a sage ceramic vase with a white blank sticker. Mask: the sticker. Output: the sticker is removed, the glaze is restored and the transparent background is kept (preserve_alpha).

Bria Eraser API removes passers-by, clutter or blemishes you paint on a mask and fills in the background. Clean product shots and photos, then try it online.
The Playground and API use the same model ID: bria-eraser. It takes an image and a black-and-white mask with the same aspect ratio, needs no prompt, erases the white area, fills in the background and returns a PNG at the original resolution.
Choose inputs and output settings for your creative goal with Bria Eraser.
Each request takes one image and one mask and returns one image. Mask type and transparency settings do not change the price; see live pricing and your task records for charges.
One image plus one mask, no prompt — three steps to erase.
The image can be JPEG, PNG or WEBP. Paint what to remove — passers-by, clutter, blemishes — white on the mask, keep the rest black, and match the image's aspect ratio.
Input
Image + mask
Output
Erased
Use manual for brush-drawn masks and automatic for masks from a segmentation tool; turn on preserve transparency for transparent inputs.
Check the result in Playground, copy it to your storage, then create asynchronous tasks with the same model ID.

}'The create request immediately returns a taskId; image generation continues asynchronously.
The mask is a black-and-white image: the white area is erased and the background is filled in, the black area stays unchanged. Paint the white area slightly beyond the object edge so shadows and edge remnants go too.
The mask must have the same aspect ratio as the image. Exporting it at the image's exact size keeps the erased area in place.
No. Bria Eraser works from the image and the mask only; requests must not include a prompt field.
Use manual (the default) for masks painted with a brush or an editor; use automatic for masks produced by a segmentation tool.
Turn on preserve_alpha to keep the input's transparent areas transparent in the result. It is off by default.
One PNG per request at the same resolution as the input image (measured: 1360 × 768 in, 1360 × 768 out). The PNG is RGBA and fully opaque unless preserve transparency is on.
The image can be JPEG, PNG or WEBP. Both the image and the mask must be publicly reachable http(s) URLs; files uploaded in the Playground are turned into links for you.
Per output image, one image per request. See the live pricing on this page for the current rate.
