Use a background this method can separate
Pick a point in a plain background, select its connected region, and review the red overlay. The algorithm follows neighbouring pixels similar to the chosen colour. It does not recognize a person, hair, clothing or objects. A matching colour inside a disconnected part of the subject is not selected unless another path connects it.
Use additional points for separate background areas. Tolerance measures the maximum difference in red, green or blue, scaled from 0–100; it is not a perceptual colour or confidence score. Higher values can reach the subject. The selection uses hard colour boundaries; it does not reconstruct fine hair, remove colour spill or infer hidden details. For complex or low-contrast scenes, manual correction may be substantial and a dedicated editor may be more suitable.
Review and correct the selection
Erase adds to the removal mask; Restore reduces it and brings back original pixels. Brush edges are antialiased by the browser. Use Selection overlay to review removal and Replacement preview to inspect the result. Point and tolerance edits make the selection stale until you select again. Rebuilding replaces brush corrections, with Undo available. History retains eight selection changes, bounded to 32 MB of current mask history. One additional complete source-recovery checkpoint is retained after Clear or a successful replacement; it is discarded when the tab closes.
Existing transparency can be filled directly: choose White or Custom colour and prepare the download without picking points. Choose Transparent to keep the remaining foreground on transparency. PNG supports transparency; JPG flattens against the chosen colour. Exports preserve image dimensions and use a local sRGB canvas. JPG is lossy, even if dimensions stay the same.
Check the actual exported image
Prepare download creates the encoded file and displays it before enabling download. Preview guides and the red overlay are excluded. Image metadata is not retained. An invalid or cancelled replacement preserves the working image, selection and prepared download. Restore previous image recovers the full source, settings, selection history and prepared download after Clear or a successful replacement. Cancel or Clear discards pending results; native decoding and encoding cannot be forcibly interrupted, while background selection runs in a terminable worker.
PNG, JPG and still WebP inputs are limited to 10 MiB, 4 million pixels and 4,096 pixels per side. PNG animation becomes a still frame. Animated WebP, GIF, SVG and HEIC are unsupported. Processing has a 30-second wait deadline. Nothing is uploaded, stored as a draft or processed by an external AI service.
Document photos need their own rules
Check whether the issuing body permits background edits. A white background does not establish passport, visa or ID acceptance; appearance, lighting, pose and other requirements still apply. Our passport print presets preserve originals, while this tool deliberately edits selected pixels.
