JPEG, PNG, WebP

How to use

Choose a static JPEG, PNG or WebP source. Check the displayed upload limits before processing.
Set Opacity percentage. Review the selected units and options before preparing the output.
Select Prepare image. Inspect the resulting preview, dimensions and file size, then download the output you need.

Why use this tool

Preserved alpha keeps the transparency change available in the downloaded image.

Before relying on the result

Compare the finished picture with its source. It reduces existing opacity across the picture rather than selectively removing a background.
