Image Vignette Tool

How Image Vignette Tool works

Image Vignette Tool is designed to darken local image edges with an adjustable radial vignette. Normalized distance from the canvas center drives a squared darkening curve outside the selected clear-center radius. Image Vignette Tool adds a focused result for this operation. For Image Vignette Tool, its displayed result gives the current settings a concrete value that can be checked before anything is copied or downloaded.

At 60 percent strength, the center is unchanged while pixels near the furthest corner are darkened by up to 60 percent. Use it to pull attention toward a centered subject or test an edge treatment before applying it in a larger editor. In Image Vignette Tool, that reproducible starting point makes later changes easier to evaluate because the underlying method stays constant.

Limits, output, and privacy

The effect is radially centered and does not follow an off-center subject unless the image is cropped or repositioned first. For Image Vignette Tool, large source images require more memory because the browser holds both source and output pixel buffers while processing. Image Vignette Tool keeps the operation client-side. With Image Vignette Tool, the page processes its source locally, then copies or downloads the in-memory result without uploading it.
