What is image compression?

Image compression is a process that reduces the size of a graphics file without noticeably impacting image quality. It’s useful for optimizing files to fit online platform (like email) requirements or for website owners to ensure faster website load time.

There are two types of image compression – lossy (JPEG) and lossless (PNG). Lossy compression focuses on removing unnecessary file data to make files as small as possible, while lossless compression focuses on retaining image quality.
