What is Image Compression Tools?

Image compression is a technology that allows you to reduce image file size.

However, if you make the image too small, the result will have more obvious pixelation. 

There are 2 types of image compression:

Lossy Compression

Reduce image file size and degrades its quality. Once a file is compressed, you cannot recover the eliminated data. 

Lossless Compression

Reduce image file size but maintain a high-quality image result. It enables you to later restore the file as needed. However, this technique can’t significantly reduce the file size. 

Why should I compress my images?
