Frequently Asked Questions
What backgrounds work best?
Solid colors (white, gray, studio backgrounds) work best. Complex textures may require higher tolerance and multiple attempts.
How does the flood-fill algorithm work?
It samples the background color from 8 edge/corner points, then floods inward removing pixels within your tolerance range.
Can I re-run without re-uploading?
Yes — adjust the tolerance slider and click Process again on the same image.
Is the output always PNG?
Yes — PNG is the only format that supports full alpha-channel transparency with no artifacts.
