White pixels turn transparent instantly — for logos, stamps and scans.
A white background stops a logo from sitting on colored layouts. Threshold-based white removal is the cleanest approach for flat graphics: edges stay crisp and semi-tones fade smoothly into alpha.
For flat graphics a precise color threshold gives a cleaner edge than segmentation — and it's instant.
White elements inside will also become transparent. For photos use “Remove background”.
