How it works

Colours are collapsed to brightness using perceptual weighting — green contributes most to how bright a colour looks, blue least — so the result matches how the eye reads the original rather than a flat channel average. Greyscale images also compress noticeably smaller.

Your privacy

This tool runs entirely in your browser — your images are never uploaded anywhere. Very large files fall back to our server, and the tool tells you before you run it when that applies. Either way, no account is needed.

Convert a photo to black and white in your browser. A proper grayscale conversion weighs the colours the way the eye does, so tones stay balanced instead of muddy — ideal for a timeless, editorial look or to remove colour as a distraction.

A proper grayscale, not flat desaturation

Simply pulling saturation to zero often leaves a photo looking muddy, because it ignores how bright each colour really is. A proper luminance conversion weighs the colours the way the eye does, keeping tonal balance so the black-and-white result has real depth and contrast.

When to go monochrome

Removing colour makes shape, light, and texture lead — ideal for timeless portraits, moody landscapes, or a consistent monochrome set for a gallery or publication. Keep your original, since grayscale discards colour information and cannot be reversed. It runs in your browser.

  • Removing colour so shape, light, and texture lead.
  • A consistent monochrome set for a gallery or publication.

Frequently asked questions

Is this just desaturation?

It is a proper luminance conversion, which keeps tonal balance far better than simply pulling saturation to zero.

Can I go back to colour?

Keep your original — grayscale discards colour information, so the black-and-white copy cannot be returned to colour.

Is it private?

Yes — the conversion runs in your browser.
