Halftone turns the smooth tones of a photo into a pattern of dots of different sizes — the technique that lets newspapers, comics, and posters print shades of grey and colour using only solid ink. Image Machine recreates it right in your browser: choose the dot size and shape, keep it as a classic two-tone ink-on-paper print or let each dot carry the original colour for a pop-art effect, and pick your own ink and paper colours. Nothing is uploaded — your image is processed locally and you download the result instantly.

Frequently Asked Questions
What is a halftone effect?
A halftone represents continuous tones using a grid of dots whose size varies with brightness — large dots in dark areas, small dots in light areas. From a normal viewing distance your eye blends the dots back into smooth shading, which is how printed photos in newspapers and comics are reproduced with a single ink.
How do I make a comic-book or pop-art halftone?
Upload your image and choose a larger dot size for a bold, visible pattern. Use the 'Colour' style to keep each dot's original colour for a pop-art look, or 'Two-tone' with black ink on white paper for the classic comic-book print feel.
Can I change the dot size, shape, and colours?
Yes. The dot-size slider controls how coarse or fine the screen is, you can switch between round and square dots, and in two-tone mode you can set any ink and paper colours — for example dark blue dots on cream for a vintage risograph look.
Is my image uploaded to a server?
No. The whole halftone conversion runs locally in your browser, so your image never leaves your device. It works offline once the page has loaded, with no sign-up and no watermark.
