The key to compressing a file is to select the right tools and steps. Using Windows' own functions, you can right-click to select "Send to" > "zipped folder" to generate a .zip format compression package, suitable for daily small file processing; if you need more functions such as encryption, volume compression or higher compression rates, it is recommended to use professional tools such as WinRAR or 7-Zip. Taking 7-Zip as an example, you can right-click to select "Add to Compression Package" to set the format, password and compression level; Mac users can directly select "Compress" to generate .zip files, or you can use third-party tools such as Keka or The Unarchiver to achieve encryption and multi-format support.

Compressing files is actually quite simple, the key is to choose the right tools and steps. Whether you want to send emails to save space or backup materials is more convenient, learning how to compress files correctly can save a lot of trouble.

The most convenient way to use the compression function that comes with Windows

If you are using a Windows system, you do not need to install additional software, and the system itself supports basic compression operations. The method is also very simple:

• Right-click on the file or folder you want to compress
• Select Send to > Compressed folder
• The system will automatically generate a .zip format compressed package. The default name is to add a .zip suffix to the original file name.

This method is suitable for daily small file processing, without taking up resources and installing software. However, it only supports zip format, and cannot set passwords or use other formats with higher compression rates, such as 7z or rar.

More functions can be achieved with compression software

If you need higher-level functions, such as encrypting the compression package, compressing the volume, or increasing the compression rate, you have to use professional compression tools such as WinRAR and 7-Zip.

Take 7-Zip as an example. It is free and has a full range of functions:

• After installation, right-click the file and select "7-Zip" > "Add to Compression Package"
• In the pop-up window, you can select the compression format (zip, 7z, tar, etc.)
• You can also set passwords, compression levels, and even split them into multiple small files (suitable for passing large files)

This method is more suitable for users who often need to upload, make backups, or protect privacy.

Compressing files on Mac is not difficult

Don't worry about Mac users, macOS also has built-in compression function:

• Right-click on the file or folder and select "Compress"
• The system will generate a .zip file, which is in the same directory as the original file by default.

If you need more options, you can use third-party tools such as Keka and The Unarchiver, which support multiple formats, encryption, volume division and other functions.

Basically these methods are all. Different systems have corresponding operating methods, and you can easily get it done by choosing the right tools.
