Frequently Asked Questions
Does this tool upload my proprietary images to any server?
No. All pixel sampling, color distance calculations, and transparent PNG generation occur 100% inside your client browser.
What is the Color Tolerance setting?
Tolerance controls the Euclidean color distance threshold. Lower values only remove exact color matches; higher values remove neighboring shades, shadows, and compression artifacts.
Can I preview my transparent image against different backgrounds?
Yes. You can toggle between standard checkerboard transparency, solid black, solid white, or blue backdrops to verify edge cleanliness.
