Halftone Generator

Turn a Photo Into a Print-Style Halftone

A halftone recreates a photo with a grid of dots — large dots in the shadows, tiny dots in the highlights — the way newspapers, comics, and screen-printed posters have reproduced images for over a century. Drop in a photo, then dial in the dot spacing, shape, and screen angle and watch the pattern build live on a canvas. Monochrome lays one ink screen over a paper color; CMYK Color runs a real four-angle separation and stacks cyan, magenta, yellow, and black with a multiply blend, exactly the way process printing overlaps its inks into a rosette.

It all happens in your browser. Your image is never uploaded, there is no watermark, and the PNG you download is pixel-for-pixel what the preview shows — the preview and the export are the same canvas.

One honest note: a halftone here is a stylizing effect, not a printer's RIP. It is built for looks — posters, shirts, social graphics — not for sending camera-ready separations to a commercial press.

What people use it for

• Comic and pop-art looks: Coarse dots and a strong screen angle turn a portrait into Lichtenstein-style Ben-Day dots.
• Screen-print and poster art: Convert artwork to a dot pattern for a hand-printed, high-contrast poster feel.
• Retro newsprint effect: Fine dots at 45 degrees give photos that inky, mid-century newspaper texture.
• T-shirt and sticker designs: Build a bold halftone graphic, download the PNG, and drop it into your design.
• Duotone brand graphics: Set your own ink and paper colors in monochrome mode to match a brand palette.
• Line and square screens: Swap circular dots for a line screen or square dots for a different print texture.

Privacy: This tool runs entirely in your browser. Your photo is processed on your own device with the canvas API and never leaves it — nothing is uploaded, stored, or sent to any server.
