Turn a photo or AI-generated image into a halftone (screentone) made of dots whose size follows the local brightness, and save it as a PNG — entirely in your browser. Get that old-newspaper, comic-book, or Lichtenstein-style pop-art look without opening a heavy image editor. It works just like print halftoning: the image is divided into a fine grid, the brightness (luminance) of each cell is measured, and darker areas get bigger dots while brighter areas get smaller ones. Use Dot spacing to set how coarse the dots are (the apparent resolution), Screen angle to tilt the grid (45° is the classic comic look), and Dot size to balance the contrast of the dots. Pick round dots or squares, and choose any ink and paper colours — so you can make a black-on-white manga look, or recolour it for a retro-print or poster feel. The preview is scaled to fit your screen, but the saved PNG is exported at the original pixel size while preserving the look of the dot pattern. Load images by dropping, clicking to choose, or pasting from the clipboard. All processing happens in your browser — the image is never sent to any server or API, so it's safe to use even where uploading files is not allowed.
How to use
- Load an image by dropping, choosing, or pasting it (nothing is uploaded).
- Adjust dot spacing, screen angle and dot size, plus the shape, ink and paper colours.
- Save the halftone image as a PNG (exported at the original pixel size).
FAQ
Is my image uploaded anywhere?
No. Loading, converting, and PNG export all happen inside your browser. The image is never sent to any server or API — it all stays on your device, so it's safe to use even in workplaces that block cloud editing tools.
What does the halftone effect do?
It replaces the image's brightness with a pattern of variable-size dots: dark areas get larger dots and bright areas get smaller ones, giving the dotted tone of newspapers, comics, and pop art. It's the same trick print uses to reproduce shades of grey with solid ink.
What are the screen angle and spacing for?
Dot spacing sets how coarse the dots are (finer looks higher-resolution, coarser gives a bolder screentone). Screen angle tilts the dot grid — 45° is the most familiar comic look. Dot size balances how big the dots grow, which controls the apparent contrast.
Will the saved image lose quality?
The preview is scaled down to fit your screen, but the saved PNG is exported at the original pixel size while keeping the look of the dot pattern. PNG is lossless, so there's no degradation beyond the halftone conversion itself.
