Timeless black and white

Black-and-white photos draw attention to shape, light and expression instead of colour. Grayscale versions are also useful for printing on a laser printer, for documents and for forms that ask for a monochrome image.

The converter uses perceptual luminance weights, so greens don't turn muddy and skies don't wash out. Use the strength slider for a partially desaturated, muted look, and open More adjustments to add contrast for a punchier result.

  • Scanned documents look cleanest in grayscale with raised contrast — then convert them to PDF.

Frequently asked questions

Is grayscale the same as black and white?

In everyday use, yes. Grayscale images contain shades of grey from black to white rather than only pure black and pure white.

Can I make only part of a photo black and white?

This tool converts the whole image. The strength slider lets you keep some of the original colour across the entire photo.

Does it reduce quality?

No. The image keeps its full resolution and format.
