Common reasons to convert

How the conversion works

The slider removes color information (hue and saturation) from every pixel while keeping brightness, so shadows and highlights stay where they were in the original photo. That's different from an old-style sepia filter — it's a true grayscale, matching what a monochrome photocopier or B&W printer would produce.

Frequently asked questions

Is this reversible?

Always start from your original color photo — the tool doesn't overwrite it, it only downloads a new grayscale copy.

Does it work on scanned documents too?

Yes, it works on any photo or scan, not just portraits — useful for making a colour scan photocopier-friendly.

Can I control how strong the grayscale effect is?

Yes, the slider ranges from a light desaturation to full black-and-white, so you're not stuck with one fixed look.
