Threshold Image to Black and White Free
Runs 100% in your browser — your files never leave your device.
Convert a sketch into crisp line art, make a stencil, or build a high-contrast mask for design work. Pixels above the threshold become white, everything below becomes black, and you control the cutoff. The binarization happens in your browser.
