Convert any image to bitmap online
This is a browser-based bitmap creator and bitmap generator in one: load a photo, logo or drawing and it becomes a two-tone bitmap image. There is nothing to install, no account, and your files never leave your device.
How to convert an image to bitmap
- Open the converter and drop your file in (or paste from the clipboard).
- Pick a dither method — Atkinson and Floyd–Steinberg suit photos; Threshold gives a hard black-and-white cut.
- Adjust pixel size, threshold, brightness and contrast until it looks right.
- Download as PNG, a real
.bmpfile, or scalable SVG.
A bitmap maker with real control
Unlike a one-click converter, you get twelve dithering methods, adjustable pixel size and threshold, brightness and contrast, plus effects like scanlines and glitch. It is a proper online bitmap editor, not just a filter.
