Frequently Asked Questions
What is Match Tolerance?
Tolerance controls how strictly pixel colors must match your target color. Lower values (10-20) only replace identical shades, while higher values (30-50) replace subtle shadows and gradients.
Can I replace white backgrounds with transparency?
Yes! Click the 'Clear (Alpha)' button as your new background color to remove the background entirely.
