How the vignette tool works
- Upload a photo.
- Adjust the strength (how dark the edges get) and size (how large the bright center stays).
- Download the result as a PNG once you're happy with the look.
The method
A radial gradient is drawn over the image, transparent at the center and fading to semi-transparent black at the edges. The gradient's inner and outer radius are controlled by the size slider, and its maximum opacity is controlled by the strength slider.
FAQ
What does a vignette effect do?
It darkens the corners and edges of a photo while keeping the center bright, drawing the viewer's eye toward the middle of the frame - a classic technique from film photography.
What does the "Size" slider control?
It sets how large the untouched bright center area is before the darkening begins. A smaller size darkens more of the image; a larger size keeps more of the frame bright.
Can I remove the effect after applying it?
Yes - set Strength back to 0, or re-upload the original image, since the effect is applied non-destructively to the canvas each time a slider changes.
Is my photo uploaded anywhere?
No. The vignette is drawn entirely on a canvas in your browser using a radial gradient - your image never leaves your device.
