Frequently Asked Questions
How is alpha transparency detected?
The tool renders the image to an offscreen canvas and samples pixel alpha values across the canvas to verify true transparency.
Is my image uploaded during analysis?
No. The file is read directly in browser memory using FileReader and Canvas APIs. No data is sent over the network.
