Image compression is a technique used to reduce the file size of digital images. By removing unnecessary data or using algorithms to simplify the image, compression makes it easier to store and share pictures without losing too much quality. This is especially important for websites and social media, where fast loading times are crucial. There are two main types of image compression: lossy and lossless. Lossy compression reduces file size by permanently removing some image details, which can affect quality. In contrast, lossless compression keeps all the original data intact, allowing the image to be restored to its original form. Both methods help manage storage space effectively.
