Halftone Generator
Turn any photo into a comic-book halftone print — the dotted look of vintage newspapers and pop-art posters. Control the dot size and the screen angle, pick your ink and paper colors, then download in full resolution. Everything runs in your browser — your images never leave your computer.
How does it work?
Halftone is how printers have faked shades of gray since the 1880s: a grid of ink dots whose size varies with the darkness of the image — big dots where it's dark, tiny dots where it's light. From a distance your eye blends them back into a continuous image. This tool rebuilds your photo dot by dot on a rotated screen grid, exactly like a printing press would.
What does the angle do?
It rotates the dot grid. Classic print screens use 45° because it's the angle the human eye notices least; 0° gives a bold graphic look, and anything in between changes the texture's rhythm. Try it together with different dot sizes.
Any tips?
High-contrast photos with a clear subject work best. If the result looks muddy, raise the contrast slider. For a pop-art poster, try colored ink on a bright paper — pink on cream, navy on yellow — instead of plain black on white.
Is it really private?
Yes. There is no upload: all processing happens in your browser using canvas and JavaScript. Close the tab and nothing remains.
