How it works
Pick a mode and grid size
Choose grayscale or color dots, then set the cell size. Each cell's average brightness decides how large its dot is drawn.
Download the halftone
Fine-tune dot coverage until it looks right, then export the finished pattern as a high-resolution PNG.
FAQ
Is my photo uploaded to a server?
No. The halftone conversion runs entirely in your browser using the Canvas API, so your photo is never uploaded anywhere.
How is the halftone dot pattern generated?
The image is divided into a grid of square cells. For each cell the tool averages the pixel brightness, then draws a circle whose radius grows as the cell gets darker, mimicking traditional print halftone screens.
What is the difference between grayscale and color mode?
Grayscale mode draws black dots of varying size on a white background for a classic newspaper look. Color mode sizes the same dots by darkness but fills them with each cell's average color for a colorful halftone poster effect.
