About Change Image Opacity
Opacity says how solid a picture is. At 100 percent it looks as normal, at 50 percent half of what is behind it shows through, and at 0 percent it cannot be seen. This tool changes the opacity of a whole picture and saves a new file you can place over anything else.
It works by scaling the transparency of every pixel, so a logo that already has clear areas keeps its shape. The preview sits on a checked background so you can see the see-through parts. Save as PNG or WebP to keep the transparency, which is what you need for watermarks, overlays and layered designs.
How to use Change Image Opacity
- Choose a picture, ideally a PNG logo or graphic.
- Slide the opacity to the level you want.
- Check the preview against the checked background.
- Keep PNG or WebP and press Download.
Common uses
- Preparing a faint watermark logo
- Making a ghost image to lay over a design
- Fading a photo to use as a slide background
- Creating a see-through badge for a video
Frequently asked questions
Which file type keeps the transparency?
PNG and WebP. JPG has no transparency, so a JPG is blended with the background colour instead.
What opacity works best for a watermark?
Between 20 and 40 percent is common. It is visible without hiding the picture beneath.
Can I make it more transparent later?
Yes. Choose the saved PNG again and lower the opacity further. Each pass multiplies the transparency.
Does it change the colours?
No. Only the transparency changes. The red, green and blue values of each pixel stay the same.
Can I make only part of the picture see-through?
This tool changes the whole picture by the same amount. To fade one part only, cut it out first with the background remover, change its opacity here, and then combine it with the other part in your editing program.
Why does the preview look checked?
The squares show where the picture is see-through. They are not part of the saved file.
