How to use the Black & White Image tool

  1. Drop one or more images.
  2. Pick Grayscale, Sepia or Black & white, and adjust the threshold for pure black and white.
  3. Download each image or all of them as a ZIP.

Three looks

  • Grayscale keeps every shade between black and white. It suits portraits, architecture and printing on black-and-white printers.
  • Sepia adds a warm brown tone for an old-photo look.
  • Black & white uses only two colors. Move the threshold slider until text or lines look clean; it works well for signatures, stamps, line drawings and scanned documents.

The conversion weighs red, green and blue the way the eye does, so the result looks natural rather than flat. To make the result smaller, use Compress Image; to change its size, use Resize Image.

Frequently asked questions

What is the difference between grayscale and black and white?

Grayscale keeps all the shades of gray between black and white. Pure black and white uses only two colors, which suits stencils, line art and cleaning up scanned documents.

How is the gray level calculated?

Each pixel’s brightness is weighted the way the eye sees color: green counts most and blue least, which keeps skin tones and skies looking natural.
