Small Business Document Size Converter Calculator — How It Works

Converts a small business document or attachment’s file size between bytes, KB, MB, GB, and TB for email and upload limits.

How it works

  1. Enter the file size of your document or attachment.
  2. Choose the unit you’re converting from (bytes, KB, MB, GB, or TB).
  3. Choose the unit you want to convert to.
  4. The tool converts using binary units: 1 KB = 1,024 bytes, 1 MB = 1,024 KB, 1 GB = 1,024 MB, 1 TB = 1,024 GB.

Why this matters

Email providers and online filing portals often cap attachment sizes (commonly 10–25 MB). Knowing your document’s size in the right unit helps you decide whether to compress a PDF, split a file, or use a file-sharing link instead.

Example

A 5 MB file converted to KB: 5 × 1,024 = 5,120 KB.
