What changing opacity actually does
Opacity is the alpha channel
Every pixel in a PNG carries a fourth value alongside red, green and blue: alpha, from 0 for invisible to 255 for solid. Lowering opacity scales that value across the whole image, so the result is genuinely see-through rather than blended with a background colour.
Why it must be a PNG
JPG has no alpha channel at all. Saving a translucent image as JPG discards the transparency and fills it with white, which is why this tool outputs PNG and why a faded JPG never looks faded once you place it.
Existing transparency is respected
The reduction is proportional, not absolute. A pixel already at half transparency drops to a quarter at 50 percent, while fully transparent areas stay fully transparent. A cut-out logo fades evenly instead of gaining a faint rectangle around it.
The watermark range
For a watermark that reads without competing, 15 to 30 percent usually works on busy photographs and 8 to 15 percent on flat or light backgrounds. Much above that and the mark dominates the image it is meant to protect.
Opacity versus a lighter colour
Lowering opacity lets whatever sits behind show through, so the same file looks different on every background. Lightening the colour instead bakes the result in. Use opacity when the image will be composited, and a lighter colour when it will not.
How to change the opacity of an image
Upload your image
Drop in a PNG, JPG, WebP, or SVG, or click to browse. The original stays on the left.
Set the opacity
Drag the Opacity slider down. The result redraws live against a checkerboard so you can see exactly how much is showing through.

Where a translucent image helps
Watermarks
Fade a logo enough to mark ownership without ruining the photograph underneath.
Background images
Knock a photo back so headings and body copy stay readable on top of it.
Overlays and ghosting
Build faded layers for before-and-after comparisons and design mock-ups.
Slide backgrounds
Drop a brand image to a whisper behind slide content instead of deleting it.
Or just ask

Type what you want changed and the assistant does it on the canvas — each step lands as a layer you can reopen, so nothing it does is baked in.
