Frequently asked questions
How do I make a picture black and white?▾
Upload the photo and keep the Grayscale effect selected. The colours are turned into shades of grey using their perceived brightness, then you can download the result.
What is the difference between grayscale and pure black and white?▾
Grayscale keeps every shade of grey. Pure black and white turns each pixel fully black or fully white, which suits signatures, scanned documents and stencils. Move the threshold to control the cut-off.
Does it reduce the image quality?▾
No. The photo is processed at its full size (up to 4000 pixels on the longest side) and saved in its original format.
