About this tool
Give JPG, PNG and WebP images a black-and-white appearance using weighted grayscale conversion. The result contains shades of gray, not just two pure colours. Dimensions and the original format are retained. PNG and WebP keep transparency. Animated images become a still frame.
How to use Black & White
- Choose the colour photo you want to convert.
- Select Make black and white to remove the colour.
- Download the grayscale image and keep your original separately.
Frequently asked questions
Does this produce only pure black and pure white?
No. It creates grayscale with intermediate shades so photo detail remains visible.
Can the original colours be restored?
Not from the grayscale file. Keep your original image if you may want the colours later.
Does transparency remain transparent?
Yes. PNG and WebP output retain transparency while changing the visible colour channels.
