How to use Create Semi-Transparent PNG
- 1. Upload your PNG. Add the image you want faded, such as overlay.png. Both photos and flat graphics work, since the opacity change applies uniformly across every pixel.
- 2. Set the opacity level. Drag Opacity level (%) from fully opaque down toward invisible, such as 30%, to set exactly how see-through the image should become.
- 3. Download the transparent PNG. Save the resulting file, rendered at your chosen opacity such as 30%, and layer it over other content wherever a faded, ghost-like overlay effect is needed.
When to use Create Semi-Transparent PNG
Create Semi-Transparent PNG sets strict fractional opacity levels from completely opaque to invisible. Create Semi-Transparent PNG is for watermarks, overlays and layered designs where an image needs to blend into whatever sits behind it instead of covering it completely.
- Adding a subtle watermark overlay. A photographer wants overlay.png to sit faintly over shared images at 30% opacity so it marks ownership without obscuring the photo underneath.
- Building a ghost-image loading placeholder. A web developer wants a faded version of an image to show while the full-resolution file loads, creating a soft placeholder effect for the page.
- Layering graphics for a collage design. A designer combining several images into one composition fades one layer to a chosen opacity so it blends with the layers beneath it.
Examples
Ghost overlay
Input
overlay.png + 30%

overlay.png rendered at 30% opacity
About the Create Semi-Transparent PNG tool
Create Semi-Transparent PNG is a free online tool that works entirely inside your web browser. Set strict fractional opacity levels from completely opaque to invisible. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 108 PNG utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with the Opacity level (%) setting, and the result refreshes the moment you change it. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
