The quality of background removal depends heavily on the original photo. A better source image usually creates a cleaner final result.

Good Lighting

Use bright, even lighting so the subject is easy to separate from the background. Avoid strong shadows crossing the subject because they can be mistaken for part of the object.

Clear Contrast

A dark object on a dark background is harder to edit. A light object on a light background can create the same problem. Choose a background that contrasts with the subject.

Sharp Focus

Blurry edges are difficult to separate cleanly. Before uploading, check whether the subject is sharp. If possible, retake the photo instead of trying to fix a blurry one.

Simple Backgrounds

A plain wall, table, sheet, or backdrop is easier to remove than a crowded room. The simpler the background, the cleaner the output usually becomes.

Conclusion

A good background removal result starts before the upload. Use clear lighting, strong contrast, sharp focus, and simple backgrounds for the best final image.
