To turn a colour photo black and white, open Image to Grayscale, add the photo, click Convert to Grayscale!, and download. Every colour becomes a shade of grey, keeping all the tones of the original — the classic black-and-white photo look.

  1. Open Image to Grayscale.
  2. Add a photo (or paste a direct link to one).
  3. Click Convert to Grayscale!.
  4. Download the black-and-white version.

Grayscale, black and white, sepia, noir — what's the difference?

For a normal monochrome photo, grayscale is what you want. "Black and white" in everyday speech almost always means grayscale.

When black and white works best

  • Portraits: removing colour draws attention to expressions, light and texture.
  • Strong light and shadow: architecture, street scenes and silhouettes.
  • Photos with distracting colours: a bright red bin or a clashing shirt disappears.
  • Bad colour: photos under mixed indoor lighting with a green or orange cast look clean in black and white.
  • A consistent look for a set of photos taken in different conditions.

Make it punchier

Straight grayscale can look flat, especially from photos taken on overcast days. After converting:

  • Increase the contrast with Brightness & Contrast for deeper blacks and brighter whites.
  • Try the Noir filter in Photo Filters for a dramatic, cinematic look.
  • Crop tighter — black-and-white photos benefit from simple, strong compositions.

On a phone

Phones have black-and-white filters built in, and they're handy for quick edits:

  • iPhone: open the photo in Photos, tap Edit, then the filters button, and choose Mono, Silvertone or Noir.
  • Android (Google Photos): tap Edit, then Filters, and pick one of the black-and-white looks.

The browser tool is useful when the photo isn't in your phone's gallery — an image from a website, a document scan, a file from a colleague — or when you're on a computer.

Converting a whole look, not just one photo

If you post a series — a photo essay, a set of portraits, a gallery on your website — convert every photo the same way so they sit together. Grayscale with the same contrast adjustment gives a consistent set; mixing grayscale, noir and sepia in one set looks accidental.

Printing black-and-white photos

Grayscale images save ink on colour printers when printed in "grayscale" mode, and they look good on matte paper. For documents and forms that require black-and-white scans, grayscale keeps them readable; for faxes or stencils, the pure black-and-white threshold version may be better.

Going back to colour?

Grayscale removes colour information permanently from the saved image — keep your original colour photo. To add colour to genuinely old black-and-white photos, the AI Photo Colorizer predicts natural colours.

Frequently asked questions

Is my photo uploaded?

No. The conversion happens in your browser.

Does grayscale make the file smaller?

Often a little, because there's less colour information, but not dramatically. For smaller files, use the Image Compressor.

Can I make several photos black and white at once?

Convert them one by one here, or apply the Noir filter in Photo Filters to each.
