About Black and White Image

Each pixel is converted to a shade of grey based on how bright it looks to the eye, so skies, skin and foliage keep their natural contrast rather than turning flat.

The same workspace can also apply a warm sepia tone or invert the colours. The image keeps its size and format.

Tips for black and white photos

  • Photos with strong light and shadow convert best.
  • Colours of similar brightness, such as red and green, become similar greys.
  • Increase contrast in your photo app first if the result looks flat.

Questions

Is grayscale the same as black and white?

In photography, yes: a black and white photo is made of greys. Pure two-tone black and white is a different effect.

Is transparency kept?

Yes, for PNG and WebP.

Can I get the colour back?

No. Keep the original if you may need it.
