Large image files can slow down websites, increase bandwidth usage, and make sharing files more difficult. Whether you're running a website, building an app, writing blog posts, or simply uploading images online, compressing images can make a big difference.
In the past, people often installed desktop software to compress images. Today, however, many powerful tools work directly in the browser, allowing you to compress images instantly without installing anything.
