Category: Image Preparation

Reduced opacity allows the background to show through the image.

Choose the reduction and preview the PNG on more than one background.

## Inputs and controls

* One image or a batch: JPEG; PNG; WebP. Static images. Up to 4 MiB per file, 12 MiB total and 4 million pixels per image. At most six source images.
* Opacity percentage. Allowed range: 0 to 100

## 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.

## Questions

### Does opacity create an invisible background automatically?

No. It reduces existing opacity across the picture rather than selectively removing a background.

### What should I check before using Image Opacity?

Prepare a supported source image and check Opacity percentage. Use the exact units shown beside the controls and replace any example values with your own inputs.
