Prepare an image the local editor can handle
Choose a JPG, PNG or WebP within the background editor’s 20 MB and 12 MP limit. For large photographs, work from a proportionally reduced copy first. The editor creates an automatic foreground mask locally; its first draft is a starting point for review, especially around hair, transparent objects, shadows and a busy scene.
The tool remains under development and testing. A clean portrait against a simple background is a different problem from a bicycle, lace fabric or glass on a cluttered table. Judge the mask on the actual subject rather than assuming that every automatic result is ready to publish.
Inspect before changing anything
Wait for processing to finish, then compare the original view with the foreground preview. Zoom into hair and the outline of clothing. Look for missing fingers, background still visible between objects and abrupt hard edges. Review the whole image as well, because an excellent hair edge cannot compensate for an accidentally removed shoulder.
Make small edits. A brush correction covering a broad region can remove useful foreground before you notice. Use a brush size appropriate to the zoom level and the feature being corrected, rather than using the same large brush around every edge.
Use erase, restore and undo
Erase removes unwanted background from the mask. Restore returns parts of the original subject that the mask omitted. Soft brush edges make gradual transitions; edge trim and softness affect the boundary treatment. Change one setting at a time so you can identify which adjustment helped.
Undo supports correction of brush mistakes one step at a time. If a stroke lands on the wrong area, undo it before adding more strokes. Reset cutout returns to the automatic mask when the manual correction has become harder to manage than starting again from that draft.
Check transparency in the exported PNG
Download transparent PNG and open it on a contrasting background. A white page alone can conceal a white fringe; a dark page can reveal it. Check both if the cutout will be reused in several designs. Transparency is an alpha channel, not a painted checkerboard or white canvas.
Keep the original photograph and the refined cutout. If a future layout requires a different crop or a softer boundary, it is useful to return to those files instead of attempting to recover detail from a flattened composition.
Match the next background realistically
Background Changer can use a solid colour, built-in backdrop or your own picture. Choose a background that makes sense with the subject’s angle and original light. Subject size and horizontal/vertical position help the composition, but they do not physically relight the person or synthesize a perfectly matching shadow.
For a product photograph, a neutral backdrop may be more convincing than a dramatic outdoor scene. Inspect the exported composition at its intended size, and keep enough space around the product for the receiving page’s crop. A refined mask and a restrained background often produce a more useful result than an elaborate scene.
Choose a white background or a transparent file
Transparent space contains an alpha value; white is an actual colour. Use PNG or WebP for a cutout that will be placed over another design. Use Background Changer when the required deliverable is an opaque white backdrop.
Review the subject against a contrasting colour before exporting. A white halo can be hard to see on white, and a dark fringe can disappear on dark. Neither a successful cutout nor a white background alone establishes marketplace or identity-photo compliance.
