JPG to bitmap, done in the browser
This is a free online jpg to bitmap converter that also handles JPEG. Photographs, which are usually JPGs, respond beautifully to error-diffusion dithering — the grain reads as smooth tone even in pure black and white.

How to convert JPG to bitmap

- Adjust pixel size, threshold, brightness and contrast until it looks right.
- Download as PNG, a real
.bmpfile, or scalable SVG.
Best settings for photos
For a JPG photo, start with the Floyd–Steinberg or Atkinson method, nudge contrast up a little, and keep the pixel size small for detail. Prefer dots? Try Halftone for a newspaper feel.
