Tip: lower feather keeps the dark area compact; higher feather spreads it softly across the whole photo.

How It Works

A vignette is a radial darkening that falls off from the center of the frame. The tool measures each pixel's distance from the image center and multiplies its brightness down as that distance grows, so the very center stays untouched while the corners dim. Everything runs on your device with the Canvas API.

Strength

Controls how dark the corners get. Around 40–60 reads as natural film vignetting; above 80 becomes a dramatic spotlight.

Feather

Controls how wide the darkening spreads. Low feather keeps a tight dark ring near the edges; high feather fades it in from near the center.

Radial falloff

Darkening follows distance from the exact center, so it looks even on any photo shape — portrait, square or landscape.

Fully local

No upload, no account. The photo stays on your device and the effect applies instantly as you drag the sliders.

An honest note: a vignette only darkens existing pixels; it cannot brighten a subject that is already in the shadows, and pushing strength very high will crush corner detail to black. Combine it with the contrast or faded-photo tools if you want to lift the center first.

FAQ

What does a vignette do?

It darkens the corners and edges of a photo while keeping the center bright, which naturally guides the viewer's eye toward the main subject. It is a classic look for portraits and vintage prints.

What strength looks natural?

Around 40–60 with a medium feather reads like real film vignetting. Go higher only when you want an obvious, stylized spotlight effect.

Can I undo it?

Yes — drag strength back to 0, or use Reset. Your original file is never modified; the effect is applied to an in-browser copy.

Is my photo uploaded?

No. The vignette is computed locally on your device with the Canvas API, so the photo never leaves and the tool works offline after loading.

Does it work on any shape of photo?

Yes. Darkening is radial from the exact center, so portraits, squares and wide landscapes all get an even, natural vignette.
