About File Compression

File compression reduces file sizes by encoding data more efficiently. ZIP is a popular archive format that can contain multiple files and folders in a single compressed file.

Common Uses

  • Email Attachments: Combine multiple files into one attachment
  • File Sharing: Easier to share one ZIP file than many individual files
  • Storage: Save disk space by compressing rarely-used files
  • Backups: Create compressed backups of important documents
  • Download Distribution: Reduce download sizes for users

Compression Levels

  • No Compression: Just packages files together, no size reduction
  • Low/Medium: Good balance between speed and compression
  • Maximum: Smallest file size but takes longer to create
