Image Threshold (Black & White Stamp Effect)
Convert any photo into a pure, stark black and white image. Create stamp effects, stencil outlines, and high-contrast silhouettes instantly.
Create Graphic Stencils
The Threshold effect analyzes an image and removes all shades of grey. Every pixel lighter than your chosen threshold becomes pure white, and every pixel darker becomes pure black. This is an essential tool for screen printers, stencil artists, or anyone looking to create a gritty, high-contrast 'Banksy' or graphic novel aesthetic.

Frequently Asked Questions
If your original photo was very dark, the default threshold might be too high. Drag the slider to the left to let more light (white pixels) into the image.
After applying the threshold, you can use our 'Remove White Background' tool to turn the white pixels transparent, leaving you with a perfect black digital stamp.
