Häufig gestellte Fragen

How do I make an image black and white?

Upload your image and drag the Intensity slider — 100% is full black and white, while lower values keep some colour for a faded, muted look. Click Download to save.

What is the difference between black and white and grayscale?

In everyday use they mean the same thing: a grayscale image maps every colour to a shade of grey between black and white. True 1-bit 'black and white' (only pure black or pure white) is different, but this tool produces the grayscale look most people want.

Can I keep a little colour instead of full grayscale?

Yes. Set the Intensity slider below 100% to partially desaturate the image, keeping a hint of the original colour for a vintage or muted effect.

Does converting to black and white reduce quality?

No. Only the colour of each pixel changes; resolution and detail are preserved. PNG export is lossless.

Are my images uploaded anywhere?

No. The conversion happens locally in your browser via the Canvas API — your images never leave your device.
