World's simplest online Portable Network Graphics (PNG) alpha channel filler. Just import your PNG image in the editor on the left and you'll instantly get a PNG with its alpha channel filled with the chosen color on the right. Once the alpha channel has been filled, all the transparent pixels in your PNG will become opaque. Free, quick, and very powerful. Created with love by team Browserling.

This browser-based tool fills all areas in a PNG image that contain the alpha channel with the selected color. This transformation (which is also known as alpha flattening) makes the given PNG fully opaque, eliminating the see-through areas, adds a solid background, and removes the smooth semi-transparent pixels (also known as anti-alised edges) that often appear around PNG object edges, resulting in sharp, clean lines that enhance the visual clarity of the image. The ability to fill alpha pixels makes this program ideal for creating visually compelling graphics that stand out in marketing materials, user interfaces, and digital art. In the options, via the color picker, you can choose a solid color to fill the alpha channel. Alternatively, you can opt for a gradient fill and change the alpha pixels to a seamless transition between colors. If you select the gradient fill, then you can also choose between linear or radial gradient modes and integrate up to four colors in the gradient. If a linear gradient is selected, you can choose its direction. If a radial gradient is chosen, you can specify its start position and the radius of color spread. Png-abulous!

This example fills the alpha channel in a PNG image of Margaret Thatcher's signature with white color, converting its transparent background into a uniform white background. The transformation creates a fully opaque signature, which is ideal for adding the signature to paper documents when printing or importing it in applications that don't support transparency.

In this example, we apply a linear gradient fill to the alpha pixels of a PNG of a hand holding asparagus. We eliminate the transparent pixels around the asparagus, creating a smooth color transition from pale-turquoise on the left to azure on the right side of the PNG. This operation overwrites the alpha channel information and the output PNG is fully opaque. (Source: Pexels.)
In this example, we enable the radial gradient mode to flatten the alpha channel of a PNG image of a pair of woven bags. We enter three green shades (#839369, #a5b58c, #5b6849) in the gradient-colors option, and when the program runs, it completely covers the transparency in the PNG with these colors. The center of the gradient is set to the middle of the PNG (behind the woven bags) and its radius is set to 500 pixels. This concentric effect creates a solid and visually pleasing background that gets darker towards the edges, enhancing the visual appeal of the image. (Source: Pexels.)
