What is Vignette Adder?

Vignette Adder darkens the edges of your photos with a smooth gradient. Control intensity, size, and softness to focus the eye on the center of the image. Works well for portraits and landscapes.

Three sliders shape the effect: intensity sets how dark the corners become, size controls where the dark region starts (a low value gives a tight spotlight, a high value barely touches the edges), and softness controls how gently the falloff transitions. Four shape modes cover the common needs — oval matches the image aspect, circular keeps a perfect circle on any crop, and square or rectangle produce straight, feathered borders for product shots and graphic layouts. Four one-click intensity presets (Subtle, Medium, Strong, Dramatic) get you most of the way to a finished look, then you fine-tune from there.

How to use

1. Upload a photo by dragging it into the tool or clicking the upload area.
2. Adjust the vignette controls: intensity (how dark), size (how wide), and softness (how gradual the fade).
3. Preview the effect and download the processed image.

When to use

• Drawing the eye to a portrait subject by darkening the busy background corners.
• Adding a moody finish to a film-emulation edit on cinematic landscapes.
• Cleaning up product photos where the four edges of the white sweep aren't perfectly uniform.

Result

A portrait photographer adds a soft vignette at 60% intensity to a headshot, darkening the corners so the viewer's eye goes straight to the face.

FAQ

What's the difference between oval and circular shape modes?

Oval matches the image's aspect ratio, so a wide landscape gets a wide ellipse and a tall portrait gets a tall one — the corners stay equally weighted. Circular forces a perfect circle, so on a wide shot the top and bottom darken more than the sides.

Why does my photo still look uneven after applying the vignette?

If softness is low the falloff is sharp and any pre-existing brightness drift in the photo becomes more visible. Raise softness to about 70 for a smoother blend, or reduce size so the gradient doesn't fight the existing light distribution.

Can I create a white or light-coloured vignette instead of dark?

This tool darkens the edges only. To brighten the corners (a halo or high-key effect), you would need an inverse vignette in a dedicated editor. The same principles of size and softness still apply when you build that in another tool.

Does the vignette work on PNGs with transparency?

Yes, the dark gradient is drawn over the visible pixels, but the surrounding transparent areas stay transparent in the export. If you flatten the result onto a white background you'll see the vignette stop at the original opaque region.

What size and intensity values look natural without being heavy-handed?

For a subtle finish try intensity 35–50, size 65–75, and softness 50–60. Cinematic looks push intensity to 70+ with softness above 70 so the darkness reaches into the middle without a visible ring. Save the result and toggle against the original to gauge.
