World's simplest online PNG background tester. Just upload a transparent PNG image into the input area, and you'll instantly get it on multiple solid-color backgrounds in the output area. In the tool options, you can define any number of background colors, choose a horizontal or vertical layout, adjust padding and spacing between previews, and scale the output to control the file size. Free, quick, and very powerful. Created with love by team Browserling.

This online tool allows you to preview how any transparent PNG (such as a logo, sticker, icon, or cut-out photo) will look on different solid-color backgrounds. It is especially useful for designers, marketers, and developers who need to check visibility, contrast, and overall appearance before publishing graphics. For example, you can verify whether a logo remains readable on both dark and light backgrounds, or see how a product sticker looks across multiple brand colors at the same time. Once you upload a PNG image with transparency, the tool places the same PNG on top of several solid-color backgrounds and combines all previews into a single output image. You can define any number of backgrounds by entering the desired fill colors in a multiline field within the options. Colors can be specified using named colors, hexadecimal values, RGB, or RGBA codes. To make color selection easier, the tool also includes a dedicated color picker that lets you choose a color from a palette and copy its RGBA value. The generated PNG previews can be arranged horizontally or vertically. You can also control the spacing and framing of the output. Padding adds space around the entire sequence of PNG previews, while the gap setting controls the distance between neighboring previews. In addition, you can choose a canvas background color that appears behind the padding and gaps. To prevent the final image from becoming excessively large, the tool provides a scaling option. A value of 100% preserves the original PNG size, while lower values (such as 80% or 50%) reduce the size of each preview before they are combined. Png-abulous!

In this example, we upload a PNG image of purple cauliflower held in hands, which will be used on a farming website. To ensure the image looks equally good across different site blocks, we test it against two corporate brand colors: #ABCBE1 (light blue) and #083E2F (dark green). We arrange the previews horizontally so the image can be compared side by side. The result clearly shows that the PNG image maintains its quality and visibility on both light and dark backgrounds.

This example tests a transparent snowflake sticker PNG against three primary background colors: red, green, and blue. Based on the sticker's appearance on these colors, we can plan the cover color for holiday greeting cards. Visually, the sticker is most contrasting on the red background, most monochromatic on the green, and most natural on the blue. To prevent the output image from being too large, we apply a 50% scaling percentage to each PNG tile. (Source: Pexels.)
In this example, we preview an electronic PNG signature of Andy Warhol on six different types of parchment paper. We input six distinct paper colors using RGB codes and generate a vertical sequence of the PNG signature tiles. As shown, the first three signatures placed on light parchment tones are clearly readable, while the subsequent three colors, which are dark, make the signature difficult to distinguish. (Source: Wikipedia.)
This example checks how the Airbnb logo PNG appears on black, white, and gray backgrounds. The previews are stacked vertically with 20px padding and 20px gaps between them. The test clearly shows that the logo works best on white or black, while gray provides a less distinct contrast. (Source: Wikipedia.)
In this example, we try to find the best white background tint for an ID card icon. We generate four variations of near-white backgrounds (seashell, honeydew, lavenderblush, and azure). We add a 1-pixel gap and padding, using a black canvas background to visually separate each PNG. Side-by-side comparison shows that warm tones (seashell, lavenderblush) cause blending, while cooler tones (honeydew, azure) provide stronger contrast. (Source: Wikipedia.)
In this example, we place a transparent "FRAGILE" stamp PNG on five different box colors to evaluate stamp visibility. We observe that the stamp is least visible on the sienna-like color (#9B6A3A). Based on this result, we recommend using a stamp with a different brightness for boxes of that color to ensure clear visibility. (Source: Vecteezy.com.)
