What is Image Compression?

Image compression is the process of reducing the file size of an image without noticeably affecting its quality. This makes images load faster online, take up less storage, and meet upload size requirements on websites.

There are two main types of compression:

Lossless Compression – Reduces size without losing image quality. All data can be restored.
Lossy Compression – Discards unnecessary data to achieve higher compression. Some details are lost and cannot be restored.

Most online tools (including this one) use lossless compression, which balances quality and file size.
