Image Vignette
Darken the edges of a photo with a smooth radial vignette that draws the eye to the center. Choose how strong the darkening is in the corners and how large the untouched center stays, and the tool fades from the clear middle to darker edges with a soft falloff that follows the shape of the image. A classic finishing touch for portraits, landscapes, product shots and film looks.
Frequently asked questions
What does the strength setting do?
Strength sets how much the corners are darkened, from 0 to 100 percent. At 50 the corners keep half their brightness and at 100 they become black. A value of 0 leaves the image unchanged.
What does the clear center size do?
It controls how far from the center the darkening begins, from 0 to 100. At 0 the falloff starts right at the center for a strong tunnel effect, while high values keep most of the image clear and darken only the outer corners. The default of 50 starts the falloff a little less than halfway to the corners.
Is the vignette round or oval?
It follows the proportions of the image, so it is round on square images and oval on landscape or portrait images. The darkening is strongest in the four corners and lighter at the middle of each edge.
How smooth is the transition?
The falloff uses a smoothstep curve, which starts and ends gently, so there is no visible ring where the vignette begins. This looks similar to the natural light falloff of a camera lens.
Can I make a white vignette?
No, this tool always darkens toward black, the way lens vignetting behaves. For a light edge effect, invert the image, add a vignette and invert it back, or use a soft border in an editor.
Does it keep transparency?
Yes, only the color channels are darkened and the alpha channel stays the same. Transparent areas are not filled.
What values work best for portraits?
A strength between 25 and 45 with a center size around 50 to 70 is usually subtle enough to go unnoticed while still guiding the eye. Stronger settings suit moody or vintage styles.
Which formats can I upload?
JPEG, PNG, GIF, WebP, TIFF and AVIF images up to 5 MB are accepted. Animated files use their first frame and images over 4000 pixels on a side are scaled down to fit. The output is PNG.
Should I add the vignette before or after other edits?
Add it last, after cropping and color adjustments. Cropping after a vignette cuts off the darkened corners and makes the effect uneven.
How is the vignette calculated?
The tool computes the distance of each pixel from the center relative to the corners and multiplies the color values by a darkening factor from that distance. The calculation is deterministic.
