Perguntas frequentes

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.

Posso manter um pouco de cor em vez de tons de cinza completos?

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.

Minhas imagens são carregadas em algum lugar?

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

What formats are supported?

Upload PNG, JPG, JPEG, WebP, or BMP, and export as PNG, JPG, or WebP.
