WebP Alpha Channel Extractor

World's Simplest WebP Tool

This free online tool lets you extract the WebP alpha channel. Just load your WebP image in the input editor, and you'll instantly get its alpha channel in the output editor. In the options, you can set custom colors for three different alpha ranges and create a three-color alpha map. In particular, you can set a color for alpha=0 (full transparency), 0<alpha<1 (partial transparency), and alpha=1 (full opacity). Created by team Browserling.

What Is a WebP Alpha Channel Extractor?

With this online tool, you can extract the alpha channel from WebP images. The tool processes the input WebP pixel-by-pixel and draws an alpha map, changing the pixel colors depending on the transparency values. It uses three different colors for drawing the alpha map, for three different alpha value ranges. The first color shows the areas where the alpha channel is 0, indicating full transparency. The second color visualizes the areas with partial transparency, where the alpha channel ranges from 0 to 1. The third color displays areas where the alpha channel is 1, indicating full opacity. All three colors can be configured in the options and by default they are black (transparency), white (partial transparency), and white (opacity). By changing the colors for various alpha values, you can quickly find accidental transparent pixels in WebP images and fix anti-aliasing problems. When extracting areas with partial transparency, the "Keep Existing Transparency" option will be helpful. It lets you maintain the original alpha channel values for translucent pixels. For example, when working with transparency gradients, it will draw them in the new color but with the alpha channel value preserved. The tool also provides information about the number of alpha pixels and prints how many pixels are transparent, partially transparent, and opaque. Webp-abulous!

Extract Alpha Channel from a Lizard Sticker

In this example, we extract the alpha channel from a WebP sticker of a lizard to gain a more detailed understanding of the sticker's transparency. To ensure a clear distinction between each transparency type, we set contrasting colors for each of them: black for complete transparency, white for opacity, and red for semi-transparency. As a result, we can clearly see the alpha channel usage within the given WebP. (Source: Pexels.)

Color of areas where alpha

Color of areas where alpha
channel is between 0 and 1.
When coloring translucent areas,

Color of areas where alpha

Preserving Alpha Channel of Translucent Areas

In this example, we create an alpha map of a WebP image with the "Keep Existing Transparency" mode enabled. This option shows the translucent areas with the actual alpha value for each pixel. We use yellow (#ffdd4f) for transparent areas and green (#518010) for translucent and opaque areas. As a result, the translucent pixel areas create a smooth gradient that blends into the background's color where the transparency is high and into the object's color where the transparency is low. (Source: Pexels.)

Required options
These options will be used automatically if you select this example.
Color of areas where alpha

Color of areas where alpha

Visualize the Boundary Between Transparency and Opacity

In this example, we extract the alpha channel from a transparent ice cream sticker and visualize the semi-transparent pixels with alpha values between 0 and 1. To do this, we set the same color, "snow" (#fcf7f7), for both transparent and opaque pixels and a contrasting color, "dark-red" (#9a0001), for semi-transparent pixels. As a result, we get a thin outline around the ice cream cone that shows its boundary. (Source: Pexels.)
