A vignette gently darkens the edges and corners of an image with a smooth radial falloff, leaving the centre bright. It is a classic photographic effect that focuses attention on the subject in the middle and gives a warm, framed feel. This tool applies a balanced vignette sized automatically to the image.
A vignette is useful for portraits, product shots, a vintage or cinematic look, or simply to draw the eye to the centre of a busy image. The output keeps your original format and dimensions - a PNG stays a PNG (with transparency), a JPEG stays a JPEG.
Everything runs entirely locally in your browser on a canvas (no upload, even offline) - your image never leaves your device. The vignette darkens toward the corners with a smooth gradient; the strength can be adjusted with a slider (default 60%) for a natural result. Animated images are flattened to a single frame.
