Why Compress PNG?

The main purpose of compressing image data is to reduce storage space. When the image meets browsing or usage requirements, the smaller the space occupied, the better. This allows more images to be stored in limited storage space, and smaller image data compression also helps improve transmission speed.

Image data compression can also be divided into lossy compression and lossless compression

Lossy compression: Lossy compression may reduce image quality. Different usage scenarios may require different image quality. For example, images on web pages rely on network transmission and typically use lossy compression. Compress image data as much as possible while meeting browsing requirements.
Lossless compression: Lossless compression typically does not reduce image quality, meaning compression is done while ensuring image quality by removing unnecessary data.
