Darken

Cinematic darkening in one click

A free, in-browser tool to darken a photo, image, or picture online and add cinematic vignettes. Choose from six gradient modes, dial in the intensity, and pick a black, white, or custom overlay color for moody, dramatic results. No signup, no watermark.

  1. Upload your photo — Open zebra.tg/darken and drag in or select the image you want to darken. It loads straight into your browser, so nothing is uploaded to a server.
  2. Pick a gradient mode — Choose how the darkening falls across the frame: full frame, bottom, top, left, right, or a radial vignette. Use full frame for an overall moody dim, or radial vignette to draw the eye toward the center.
  3. Set the intensity — Drag the intensity slider to control how strong the darkening or vignette looks, from a subtle deepening to a dramatic, cinematic falloff.
  4. Choose an overlay color — Keep the default black for classic shadows, switch to white to fade and lighten edges, or enter a custom hex value to tint the effect to match your photo's mood.
  5. Download your image — Once you like the look, download the edited photo directly to your device. No account or watermark required.

Is the Darken tool free?

Yes. Zebra's Darken tool is completely free to use with no signup required and no watermark added to your photos.

Does it work on mobile?

Yes. Zebra runs in your browser, so you can darken photos and add vignettes on a phone or tablet just like on a desktop, no app to install.

Are my photos private?

Your image is edited right in your browser, so it stays on your device rather than being uploaded to a server.

What darkening styles can I create?

You get six gradient modes: full frame, bottom, top, left, right, and a radial vignette. Combined with adjustable intensity, they work well for moody photos, a cinematic look, dramatic portraits, and classic vignettes.

Can I change the color of the darkening effect?

Yes. The overlay color defaults to black, but you can switch to white or enter any custom hex code to tint the effect to suit your photo.

How do I darken a photo or image online?

Open the tool, drop in your picture, pick a gradient mode, and drag the intensity slider until the image looks as dark as you want. It all happens online in your browser, then you download the result, no app needed.

Will darkening reduce my photo's quality?

The tool applies the overlay to your existing image, so it preserves your original resolution without forcing it to a smaller size.
