How To Compress A File On Mac – Complete Guide


When you are compression sizing a file, it’s important to understand the difference between “compressing” and “ compressing .” Compressing a file means to change its size, while compressing means to change its contents. A common problem that can arise from compressed files is that user data remains in the file even when the file size becomes smaller than what is allowing for readingness.

If not, you will need to use a tool like 7-zip or Snagus to decompress the file.
