This browser-based tool creates fully customized PNG (Portable Network Graphics) images of any shape, size, color, and transparency settings. It's especially useful for developers, designers, and QA specialists who require custom images for testing. With it, you can generate huge canvases, tiny pixel samples, long horizontal or vertical strips, completely transparent files, semi-transparent overlays, solid backgrounds, or complex multi-color gradients. To get a PNG, first, navigate to the tool options and specify the exact width and height of the PNG you need in pixels. This allows you to generate images of any shape and size, whether it's a massive 4000x4000 pixel square, a small 8x8 icon, or a long, thin horizontal (3000x10) or vertical (10x3000) banner. Then you can set the color properties of your custom PNG. You can select the "Solid Color Background" option to create a PNG with a uniform background. This mode perfect for creating opaque, semi-transparent, or completely transparent PNG images. To create an opaque PNG, simply enter the color's name or code in this option. To create a semi-transparent PNG, modify the color's alpha channel value to a value less than 1. To create a fully transparent PNG, use the special color code "transparent". If you need a more complex PNG, switch to the "Gradient Color Background" mode. When this mode is selected, enter at least two colors in the option that accepts a gradient list. The accepted color formats are one per line or space-separated. Here you can include as many colors as you need to produce a PNG with smooth multi-step gradient transitions. Additionally, the tool supports two gradient background types: linear gradient background and radial gradient background. The linear gradient creates a straight-line transition between your colors. By default, the transition runs from left to right (which is equal to 0 degrees). You can adjust the direction of the gradient line in the option by entering a specific angle (in degrees) or by interactively rotating the gradient wheel in the output editor with your mouse. The radial gradient transitions colors in all directions from a single central point. You can control the distance of the transition by setting the gradient radius in pixels (the default is 400 px). You can also define the exact center point by entering the "Center X" and "Center Y" coordinates in the options. By default, the gradient center is placed in the middle of the PNG frame, but you can easily reposition it by clicking anywhere in the output editor. Such gradient-based PNGs are often used for testing dithering algorithms and benchmarking image encoding pipelines. Png-abulous!

In this example, we generate a very large custom PNG with dimensions of 4000 by 4000 pixels. The background fill option is set to a solid color, resulting in a massive white square. This canvas can be used as a neutral background for any project that requires a high-resolution, blank PNG image.
This example creates a very tiny PNG image of just 5x5 pixels. We set the pixel color to red, which results in a red square PNG. Although small, such pixel-sized images can be handy as placeholders and icons, or can be used for testing pixel-level rendering in apps.
In this example, we create a stretched horizontal PNG that is 3000 pixels wide and only 10 pixels tall. Instead of using a solid color for its background, we apply a linear gradient that goes from dark magenta to indigo at 0°. This gradient flows smoothly from left to right along the full length of the strip.
This example generates a long vertical PNG image, which can be useful for testing vertical scroll behavior. We set the PNG width to 10 pixels and the PNG height to 3000 pixels. To make scroll testing easier, we apply a repeating black-and-white linear gradient. The gradient alternates between 9 white and 9 black color stops, smoothly blending from one to the other from bottom to top, as the linear gradient axis is oriented vertically at a 90° angle.
In this example, we create a custom square PNG by setting both custom dimensions to 500 pixels. For color properties, we select a radial gradient that begins at the center point of the image (x=250, y=250) and extends outward within a radius of 300 pixels. The gradient starts with transparency at the center and gradually transitions through dodger blue color into a dark blue color near the edges.
This example demonstrates how to generate a fully transparent PNG with custom size. The PNG dimensions are set to a rectangular shape with a width of 640 and a height of 400 pixels. In the PNG color option, we enter the value "transparent", which creates a see-through background.
In this example, we modify the transparency property of the PNG file. We set the background color in RGBA format to "rgba(0, 127, 0, 0.5)". The last parameter in the RGBA color code is the alpha channel and its value is equal to "0.5". This value changes the opacity of the whole PNG to 50%. The size of the final PNG is set to 450 by 450 pixels, making it useful for testing translucent UI elements (you can place this PNG on top of other elements to partially see the content below it).
This example creates a custom PNG that uses just one opaque color. The dimensions of the PNG are changed to 600 by 500 pixels (in the options) and it's filled with a solid "coral" color. Because the chosen color is fully opaque, the result is a bright rectangle. This image is useful for background blocks or simply testing how applications render solid colors without transparency.
In this example, we build a custom rectangular 600×300 PNG image with a rich linear gradient. It flows horizontally at a 0° angle through six vivid colors: orangered, yellow, lawngreen, darkturquoise, cornflowerblue, and blue. Such a PNG is useful for testing gradient rendering, as it helps verify smooth color transitions on different screens.
