This browser-based tool increases the thickness of icons in PNG format. You can make the icon more noticeable and clear while preserving its background and brand colors. In the tool's options, you can set the number of pixels to be added to the icon's outline. This determines how much thicker the icon will become – the higher the value, the wider the outline. Once you upload the icon, the tool automatically detects its background color (the program works only with icons on a solid background, such as transparent, white, or red). However, if the background color is incorrectly detected, you can manually specify the correct color by clicking on it in the preview. After setting the icon's background, you can choose the color of the added pixels. You can select the "Auto Color Detection" mode in the options, which automatically determines the color of the added pixels, which is especially useful for multi-colored icons. If you want to use a specific color for the new pixels, activate the "Use Specific Color" option and adjust the desired shade. Additionally, the tool allows you to choose where the thickness will be added. The "Thicken Only Outer Sides" option adds pixels only to the outer edges of the icon without affecting the internal enclosed areas. This helps preserve small internal details of the icon when enlarging it. You can also make the transition between the outlines and the background smoother by activating the "Make Icon Smooth" function, which makes the pixels at the edges semi-transparent. If you're looking to make your icon thinner, use our tool Make Icon Thinner. Png-abulous!

In this example, we increase the thickness of a download icon by adding 4 pixels to its outline. The tool automatically detects the icon's background color (setting it to transparent) and also determines the stroke color (setting it to black). (Source: Wikipedia.)
In this example, we thicken the incognito icon placed on a white background. The tool automatically detects the white background and substitutes it in the option, and also automatically detects the outline color and uses it for the new pixels. We increase the width of the icon by 10 pixels, thickening only the outer edges of the icon, and also make the icon smooth on the edges. (Source: Wikipedia.)
In this example, we increase the thickness of the colorful TV icon. We add 8 pixels on all sides, keeping the transparent background behind the icon. To ensure the added pixels are the same color as the elements of the original icon, we activate the "Auto Color Detection" mode. (Source: Wikipedia.)
In this example, we increase the thickness of the onion icon by 10 pixels. We automatically detect the light beige background color and also automatically add pixels of the same color as the icon. As a result, the thickened version of the onion icon has the same gradient color as the original icon. (Source: Wikipedia.)
In this example, we use a custom outline color to increase the thickness of the icon. We enable the "Use Specific Color" mode and enter the green color #699732 for the outline. We thicken the cactus icon by 8 pixels, resulting in a clear green outline that highlights the icon on any background. (Source: Wikipedia.)
