How this works in your browser
The tool samples the four corners of your image, averages them into a background colour, and then floods inward from every edge pixel, making transparent any pixel whose Euclidean distance in RGB from that colour falls inside your tolerance. Spreading from the edges rather than checking pixels independently is deliberate: it means a subject in the middle of the frame that happens to share the backdrop colour is not erased along with it. A second pass then reclaims enclosed pockets, areas that match the background but were sealed off by a thin barrier such as a drop shadow, applying the same per-pixel colour test so it can never expand into the subject. There is no machine learning model involved anywhere, which is precisely why it is instant and private, and equally why it needs a plain backdrop to work against.

Frequently asked questions
Does this work on any photo?
It works best when the background is a solid or near-uniform colour, like a product photo on white or a logo on a plain backdrop. It is not a full AI subject-detection tool, so busy or textured backgrounds will not remove cleanly.
Can I adjust how aggressive the removal is?
Yes, a tolerance setting controls how close a pixel’s colour needs to be to the sampled background to be removed.
What format is the output?
PNG, since it needs to support a transparent background.
Why did part of my background survive?
Almost always because something separates it from the edge. The removal spreads inward from the border, so a soft drop shadow, a seam in a backdrop or a stray dark line can enclose an area and block it. A second pass reclaims most enclosed pockets, but raising the tolerance is the usual fix when a stubborn patch remains.
Why did it erase part of my subject?
Because that part is close enough in colour to the sampled background to fail the same test. A white shirt on a white backdrop is the classic case. Lower the tolerance until the subject stays intact, and accept a slightly less complete cut.
Will this work on a photo taken at home?
It depends entirely on the backdrop, not the setting. A phone photo against a plain wall usually works well. The same object on a patterned rug, a bookshelf or grass will not, because there is no single background colour to match against.
What tolerance should I start with?
The default of 30 handles most product shots. Raise it when a shaded or uneven backdrop leaves patches behind; lower it when edges of your subject start disappearing. Adjusting and re-running is instant, so it is worth trying two or three values.
Is my image uploaded anywhere?
No. The pixel analysis runs inside your browser tab.
