Comic-book dots

Halftone rebuilds an image out of dots whose size follows the tones — large dots in the shadows, tiny ones in the highlights — the retro effect of printed comics and newsprint. Control the dot spacing, rotate the grid, and set the dot and background colours, all previewed live.

High-contrast photos and portraits work best; a smaller spacing keeps detail, a larger one gives a bolder pop-art feel. It’s drawn in your browser and never uploaded. For a two-colour treatment instead, see Duotone.

Frequently asked questions

What is a halftone?

The printing technique that reproduces shades with dots of varying size — big dots in dark areas, small in light. It gives the retro comic / newsprint look.

What image works best?

High-contrast photos and portraits. Use a smaller dot spacing for detail, larger for a bolder pop-art effect.

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

  • No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
  • No limits. No file-size cap, no queue, no watermark, no account.
  • Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
