WebP Opacity Changer

World's Simplest WebP Tool

This free online tool lets you change the opacity of a WebP image. Just load your WebP image in the input editor, and you'll instantly get a semi-transparent WebP in the output editor. In the options, you can precisely adjust the opacity level, select the opacity region, and choose between uniform and gradient opacity types. Created by team Browserling.

What Is a WebP Opacity Changer?

With this online tool, you can adjust the opacity level of WebP images. Opacity is a parameter that defines the visibility of pixels in a WebP. It's measured in percentage, where 0% means "no opacity", which makes all pixels fully transparent and invisible, and 100% means "full opacity", which makes all pixels opaque and removes all transparent or semi-transparent pixels. To use the tool, simply open a WebP in the input editor and select the area where you want to change the opacity. This can be done directly in the input editor by adjusting the edges of the area or through the options by specifying exact numerical values of the opacity area – its left and top positions and its size as width and height. The opacity level is also adjustable in the options via a percentage value from 0% to 100%. You can uniformly change the opacity level in the whole WebP, just the selected region, or create a gradient transition of opacity. In the case of the opacity gradient, you can choose between a linear gradient and a radial gradient. A linear gradient smoothly changes the opacity of pixels along a straight line, while a radial gradient changes the opacity from the center to the edges, similar to a ripple in water. For the linear gradient, you can choose the opacity change direction: left to right, right to left, top to bottom, and bottom to top. For the radial gradient, you can specify the opacity radius and direction: inside out (from center to the edges) or outside in (from edges to the center). Webp-abulous!

WebP Opacity Changer Examples

Change the Opacity of the Entire WebP

In this example, we slightly reduce the opacity of the entire WebP image of water waves. We set the opacity to 70% and select the "Uniform Opacity" mode. This results in a 30% translucent WebP image, allowing a little bit of content underneath it to be visible. To select the entire WebP, we leave the top, left, width, and height options empty.

Create a Fading Opacity Effect

In this example, we apply a fading linear gradient opacity effect to a WebP photo of a sunset over the ocean. We select a rectangular area below the horizon line and gradually decrease the pixel opacity from 100% to 20% as they move downward. This results in a fully opaque sky above the horizon and gradually fading ocean pixels, with the bottom row of pixels being just 20% opaque (which is the same as being 80% transparent).

Create a Focus Point via Radial Opacity

This example uses the radial opacity method to make the bowl of macrons the central focus point of the WebP. The center of the opacity gradient is set to the center of the image, it's directed from the inside out, and its radius is set to 280 pixels. This configuration makes the edges of the WebP transparent while keeping the macarons in the center of the WebP fully visible. (Source: Pexels.)
