Inspect Cutout Edges: Hair, Fabric and Product Halos
Find missing subject pixels and leftover background with contrasting previews, then refine the mask without shaving away useful detail.

Determine whether the problem is the mask or the color
A cutout edge can look wrong for different reasons. The selection may retain a strip of background, remove part of the subject or leave partially transparent boundary pixels that contain the old background's color. A reflection inside a glossy product is part of the photographed subject, not necessarily stray background.
Compare the cutout with the original before erasing. If a dark rim is genuinely on a reflective mug, deleting it can alter the product's shape. TheImageIs background tool refines transparency; it does not promise to recolor every contaminated edge or reconstruct missing hair.
Give hair, fabric and rigid edges different checks
For hair, inspect the outline and gaps between strands. A too-tight mask can turn wisps into a solid helmet shape; too much retained background can create a haze. Preserve believable volume while accepting that the source may not contain enough separation for a perfect extraction.
For fabric, compare the cuff or seam with the original rather than enforcing a fixed number of soft pixels. For a box or phone, follow straight edges and corners for accidental dents or jagged steps. An appropriate transition depends on source resolution, focus and the final display size.
Use the actual refinement controls
Run automatic selection, then switch between Selection and Cutout views. Use Restore for missing subject areas and Remove for unwanted background. Reduce the brush size near a narrow handle or strand, and adjust softness to avoid a harsh cut or a broad dissolving edge.
Make short corrections and use Undo if the contour changes too much. A large soft brush can affect more of the boundary than expected. Check the edited area against the original after each meaningful change rather than painting around the entire outline at once.
Preview contrast, then export the intended background
Test a dark background to reveal pale fringe and a light background to reveal dark remnants. A neutral background can help judge the overall shape. In the tool, choose Solid color for these checks; those colors become part of the export if left selected.
Switch back to Transparent before downloading a reusable transparent PNG. If the destination requires a fixed white background, select white intentionally and inspect that version. Reopen the download and place it over the destination background: a clean checkerboard preview alone is not the acceptance test.
Repair one difficult cutout boundary
A guided exercise, not a benchmark. Inspect your own output; results depend on the source and settings.
- Open Remove Background, run selection and identify one specific flawed region.
- Compare that region with the original, deciding whether it needs Restore or Remove.
- Refine with a small brush and compare light and dark solid-color previews.
- Choose Transparent or the intended final color before exporting, then inspect the downloaded PNG.
The subject's contour remains accurate, unwanted background is removed and the export has the intended transparency or solid color.
