Newsprint shading
Floyd–Steinberg dithering spreads the error of each rounded pixel to its neighbors, building grey tones from scattered black dots. Close up it looks grainy; at arm's length it glows like an old newspaper photo.
The technique defined early Macintosh art and retro games. Portraits, pets and still lifes gain handmade charm that flat thresholding cannot match.
Best sources for dots
Smooth gradients and soft photos dither beautifully, while already-noisy images turn chaotic. Clean, well-lit originals reward you with the most elegant dot fields.
View the result at 100% before judging: thumbnails hide the texture. PNG preserves every dot perfectly for print, while JPG smudges fine dots if you compress hard.
Vintage math, modern privacy
A forty-year-old algorithm runs anew on your machine for every image you drop in. Heritage techniques, zero heritage surveillance: nothing about your photos is recorded.
The tool works offline after first load, so basements, planes and cabins are all fine studios. Your dotted masterpieces download straight to your disk.
Questions
Are my images uploaded when I use this?
No. Everything runs inside your browser on your own device. Your files are never sent to us or to anyone else.
Why does it look grainy up close?
Each dot carries the rounding error of its neighbors, so close-up grain is the mechanism itself. Step back or zoom out and the dots melt into smooth shading.
Is the result only black and white?
Yes. Every pixel becomes pure black or pure white; all the grey you see is an illusion built from dot density.
Is it free?
Yes. Free to use, with no sign-up, no watermark and no daily limits.
