How to Add a Vignette to a Photo (Free, In-Browser)

July 6, 2026

To add a vignette, upload your photo to the ByteTools Vignette tool, set the size and strength sliders, choose a dark or light effect, and click Download PNG. The tool draws a smooth radial fade around the edges of your image directly in your browser, so the effect is applied without uploading your photo anywhere.

A vignette gently darkens (or lightens) the edges of a picture to pull the viewer's eye toward the center. This guide shows exactly how to apply one and what each control does.

What a vignette does

A vignette is a soft gradient that fades the corners and edges of an image. Darkened edges create a moody, cinematic frame that focuses attention on your subject; lightened edges create an airy, high-key look. It's a classic finishing touch for portraits, product shots and atmospheric landscapes, and because the fade is a smooth radial gradient there are no hard lines.

Step by step

Upload your image. Drop a photo into the upload area or click to browse your device.
Set the size. This controls how far the vignette reaches inward from the corners. A small size keeps the effect at the very edges; a large size draws it closer to the center.
Adjust the strength. Move from a whisper-soft fade to a dramatic, heavy shade depending on the mood you want.
Choose dark or light. Dark shades the edges toward black; light fades them toward white for a bright, dreamy style.
Download the PNG. When the live preview looks right, click Download PNG to save the result.

The preview updates as you drag the sliders, so you can dial in the look before saving.

Understanding the two controls

Control	What it changes	Try this
Size	How far the fade reaches inward	Small for subtle framing
Strength	How dark or light the edges get	Low for a natural look
Mode	Dark vs light vignette	Dark for cinematic, light for airy

Why it's private

The vignette is rendered locally on an HTML canvas using your browser's own graphics, so nothing is sent to a server. Your photos never leave your device, which makes the tool safe for personal shots, client work and unpublished product images alike. It also means it keeps working offline once loaded.

FAQ

What file format does the vignette tool output?

It exports a PNG, which preserves quality and is widely supported. You can drop that PNG straight into a design, a document or a social post.

Can I make the vignette barely noticeable?

Yes. Keep the strength low and the size small for a subtle frame that most viewers won't consciously notice but that still guides the eye toward your subject.

Do I lose image quality when adding a vignette?

The tool only paints a gradient over your existing pixels and exports a PNG, so the underlying detail is preserved. The only change is the intentional darkening or lightening at the edges.

Does the tool work on my phone?

Yes. It runs in any modern browser, including mobile, since the rendering happens on the device's own canvas. Uploading and downloading work the same way as on desktop.
