What is file compression?

File compression is the process of reducing the amount of storage space required by a file. A smaller file can be easier to upload, send by email, store and share.

Different file types use different methods of compression. For example, image compression can reduce the amount of data used by a photograph, while PDF compression can reduce the size of a document by optimizing images and other content inside it.

Why would you compress a file?

Large files can become difficult to send through email, upload to websites or store on devices.

Compressing a file before uploading it can help when a website has a maximum file-size limit.

Image compression can also be useful for websites, where unnecessarily large images may increase the amount of data visitors need to download.
