WebP to Grayscale (Black & White)
Convert WebP images to black and white — private, in your browser
Turn a WebP black and white
Black and white gives an image a timeless, editorial feel and can unify a set of photos that were shot in wildly different lighting. Converting to grayscale strips out all color and keeps the tonal detail, so contrast, texture and mood come through. This tool turns your WebP monochrome and saves it straight back to WebP.
Drop one WebP or a whole batch, and the preview shows the black-and-white result at once. Adjust the quality slider if you want a lighter file, then download the image — or a ZIP of the set. Any transparency in the original is carried through untouched.

Why go black and white?
A cohesive, timeless look
Grayscale unifies mismatched photos and lends an editorial, classic feel that color sometimes distracts from.
Focus on form and contrast
Removing color pushes attention to shape, texture and light, which is why so many portraits and product shots work in monochrome.
Batch and private
Convert a whole set at once, entirely in your browser, so nothing is uploaded and the look stays consistent across every image.
Frequently Asked Questions
What does grayscale do to my image?
It removes all color information and keeps only the brightness of each pixel, turning the WebP into a black-and-white (monochrome) image while preserving detail and contrast.
Is grayscale the same as lowering saturation?
Grayscale is the full extent of desaturation — zero color left. Partial desaturation keeps a hint of color; this tool takes it all the way to neutral black and white.
Does converting to grayscale make the file smaller?
Often a little, since there is no color to encode, but the main reason to use it is the look. Keep the quality high to retain smooth tonal gradients.
Is transparency preserved?
Yes. Only color is removed; any transparent areas in the WebP stay transparent in the grayscale result.
Can I convert several images at once?
Yes. Add a batch of WebP files and download them all as a single ZIP of black-and-white images.
