Compress PNG Images Online

In the realm of digital files, compression entails shrinking a file by eliminating certain bits of information. Sometimes, these bits are empty or superfluous, resulting in a reduction in size while maintaining the file’s appearance鈥攖his is termed as lossless compression. Conversely, when bits affecting the file’s quality are removed, it’s referred to as lossy compression.

The tool featured on this page performs a type of lossy compression by reducing the available color palette of a PNG.

PNGs are well-suited for graphics, logos, and simple designs due to their support for transparency. This feature enables placing a PNG atop another image while only covering specific parts of the underlying image鈥攁 capability not shared by many other image formats, including JPG.

PNGs support either 24-bit or 8-bit colors. Higher bit support equates to a broader color spectrum for the PNG鈥攁nd a larger file size. For instance, if your website features a simple logo saved as a 24-bit PNG, it may be occupying unnecessary space and slowing down your page load time. Converting this image to an 8-bit palette will shrink the file size without perceptibly affecting its quality. Consequently, you’ll have a smaller file consuming less storage space, thereby enhancing page loading speed.

Compressing numerous PNGs on your webpage to 8-bit could lead to significant improvements in your website’s speed.
