File Size Analyzer

Drop or select one or more files to see detailed size information, per-file breakdowns, and type distribution.

How It Works

This tool reads file metadata directly in your browser to determine exact file sizes. No file contents are uploaded or transmitted — everything is processed locally on your device using the browser's File API.

Size units are displayed in binary (1024-based) prefixes as used by operating systems: 1 KB = 1,024 bytes, 1 MB = 1,024 KB, and so on.

Type distribution groups files by their extension and shows how much of the total size each type accounts for.

Common Reference Sizes

  • Text document: 10–100 KB
  • High-res photo: 3–10 MB
  • MP3 song: 3–10 MB
  • HD video (1 min): 100–200 MB
  • RAW photo: 20–80 MB
