Change PNG Opacity
Make a PNG translucent — set an opacity from 0 to 100% and every pixel's transparency scales to match. Drop one image or a whole batch. It runs in your browser, so nothing uploads, and it respects any transparency the image already has rather than flattening it.

How the opacity is applied
Each pixel's alpha value is multiplied by your percentage. At 50% a fully-opaque pixel becomes half-transparent; a pixel that was already partly transparent gets proportionally more so. The output is always a PNG, because that's the format that can actually store the transparency — save this as a JPG and the translucency collapses onto a solid background.
Common uses
- Watermarks and overlays — a faint logo you'll place over other content.
- Ghosted UI states — a disabled or placeholder version of an icon.
- Layering — softening an image so text on top stays readable.
FAQ
How do I make a PNG semi-transparent?
Drop it above, set the opacity percentage, and click Apply. Lower numbers mean more see-through. It's processed in your browser, nothing uploaded.
Will it keep the transparency the image already has?
Yes — the effect scales existing alpha rather than replacing it, so transparent regions stay transparent and everything else fades proportionally.
Why is my semi-transparent PNG solid when I open it somewhere?
That viewer is probably compositing it onto a white (or black) background, or the file was re-saved as JPG. Transparency only survives in formats that support alpha, like PNG or WebP.
