Real dot-based halftone
The image is divided into a grid and each cell is drawn as a black dot whose size follows the local darkness, exactly how newspapers and comics reproduce photos.

Overview
About the Halftone Image Effect
Convert an image to halftone dots free online for a retro newspaper print look, with an adjustable dot spacing. Rendered on your device — nothing uploaded.
How halftone reproduces tone
Printers cannot lay down a continuous shade of grey, so they cheat with dots. A halftone divides the image into a grid and draws one dot per cell, sizing each dot according to how dark that area is — big dots for shadows, small dots for highlights, none for pure white. From a distance your eye blends the dots back into smooth tone.
The retro print look
This is the exact technique behind newspaper photographs, vintage magazine pages and comic-book shading. Applying it digitally gives artwork an authentic printed, pop-art feel that flat digital images often lack.
Choosing dot spacing
Smaller cells mean more dots and finer detail, closer to real newsprint. Larger cells make the dots obvious and graphic, which suits posters and stylised art. Bold, high-contrast subjects hold their shape best at any spacing.
Computed on your device
The dot grid is calculated per pixel on an in-browser canvas and exported as a lossless PNG, so the dots stay perfectly crisp and your source image is never uploaded.

Questions
Frequently asked questions
Short, honest answers about quality, limits and privacy.
What does the dot spacing control?
It sets how large each halftone cell is. Small spacing gives many tiny dots and finer detail; large spacing gives big, chunky dots and a coarser, more graphic look.
Which images halftone best?
High-contrast subjects like portraits against simple backgrounds. Because the output is black dots on white, images with a clear tonal range produce the most recognisable result.
Is halftone the same as posterize?
No. Posterize reduces the number of colour levels but keeps solid areas; halftone simulates continuous tone using only dots of varying size, like real print.
