How to black & white image converter
- 1Upload your color image.
- 2The preview converts to black and white automatically.
- 3Choose a format and download your grayscale image.
Black-and-white (grayscale) conversion removes color and keeps only brightness, which can make a photo feel timeless, dramatic, or more focused on shape and texture. It is also useful for documents, scans and print jobs that don't need color.
The conversion is applied instantly with an accurate luminance formula. Everything runs locally in your browser using the HTML canvas — your image is never uploaded to a server, so it stays completely private and there is no waiting for uploads.
Because the tool keeps your image's original resolution, the black-and-white result is exactly as sharp as the color original.
Need to change the shape, not just the size?
When you resize to a different aspect ratio, you normally have to crop or add bars. Our AI outpainting tool generates new matching background so your photo fills any canvas without losing a thing. Sign in for 3 free AI generations.
