Image Opacity
Set the whole image to a chosen opacity (0–100%) and save as PNG with a real alpha channel. Existing transparency is multiplied, not replaced.
A little guidance. A better result.
How to use Image Opacity
Set the whole image to a chosen opacity — real alpha channel, PNG out.
Prepare your input
Open an image.
Use the workspace
Choose opacity and inspect the transparency preview.
Check your result
Download PNG and test it over the intended background.
Know the limits
Opacity multiplies existing alpha; it does not recover opaque pixels from already transparent areas.
