This tool adds an opaque or a transparent border to PNG pictures. You can select one of three modes where the border will be rendered. If it's the inside, then the border will be drawn inside of your PNG and the picture dimensions will not change. If you choose the outside, then the PNG dimensions will extend by the border width and it will be rendered around the picture. If you choose the middle, then the PNG will get expanded by half the border width and a half will be drawn on the inside and a half on the outside. By default, the border is drawn on all sides of the PNG image and it encloses the PNG in a square. However, you can choose one or more sides where to draw the border. For example, you can add a border only to the left and right side of the PNG, or only on top and bottom, or just one side. The width of the border can be specified in the options using pixel units (by default it's 20 pixels). You can also set any color for the border fill and specify it by name, hex code, or select it from the palette in the options. As the PNG image format supports transparent and translucent colors, you can enter them in the options thru the "RGBA(R,G,B,A)" function. If the border is completely transparent and invisible (alpha channel is 0%), then the preview will display dashed regions that show the thickness of the borders and where they will be added. This line disappears when the image is downloaded. In addition to the main features, you can round the corners of the border using the "Round Border" option. You can customize the corner radius for each individual corner: top left, top right, bottom left, and bottom right. If the input PNG has a square shape, you can create a circular border around it. To do this, you need to make the rounding of each corner greater than or equal to half the width or height of the PNG. Any added border you can also remove in our reverse tool Remove a Border from PNG. Png-abulous!

This example adds a 40-pixel centered border to a PNG image of a cloudy day in the mountains. 20 pixels of the border are drawn outside of the image and the other 20 are drawn on the inside. The border is filled with a blue semi-transparent color rgba(58, 112, 121, 0.6), where the alpha value of 0.6 means that the color is 60% opaque and 40% transparent. The inner and outer sides of the border are clearly visible through the translucent pixels. (Source: Pexels.)
This example adds a completely opaque inner border to the left and right sides of a PNG skateboard photo. The border is drawn over the existing photo content on the edges and this operation doesn't resize the original PNG. The thickness of the left and right borders is 30 pixels and the color of the border is "tan". (Source: Pexels.)
In this example, we surround a Walt Disney castle PNG with a border that goes on three of its sides. As the 40-pixel border surrounds the PNG, it's drawn on the outside of the picture. The border adds empty space on the left, right, and top sides. To view the exact boundaries of the border, click on the example and check the preview window. It will be surrounded by dashed lines.

In this example, we add a circular border around the PNG image of a leaping dog. We round the corners of the border to a radius of 330 pixels, which is sufficient to create a perfect circle around the square image. We use a burlywood color and set the border width to 25 pixels. (Source: Pexels.)
In this example, we add a decorative border with an unusual shape to a vibrant PNG image of a citrus composition. We apply the border only to the top and bottom sides and activate corner rounding. We round the top left and bottom right corners to 400 pixels, and the top right and bottom left corners to 200 pixels. We fill the border with an orange color, resulting in a unique and dynamic border around the PNG. (Source: Pexels.)
