Instantly convert between bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes with our powerful converter tool.
Convert between different digital storage units with high accuracy
Use this free Byte Converter to convert digital storage units with high accuracy and speed. Whether you're managing file sizes, cloud storage, or bandwidth, this tool helps you convert between bytes, kilobytes, megabytes, gigabytes, terabytes, and more — in just a click.
The smallest unit of digital storage, typically representing a single character.
1,000 bytes (Base-10) or 1,024 bytes (Base-2)
1,000 KB (Base-10) or 1,024 KB (Base-2)
1,000 MB (Base-10) or 1,024 MB (Base-2)
1,000 GB (Base-10) or 1,024 GB (Base-2)
1,000 TB (Base-10) or 1,024 TB (Base-2)
Storage maths has a famous trap: a kilobyte is 1,000 bytes in decimal (base-10) but 1,024 bytes in binary (base-2) — which is why drives and operating systems disagree about sizes. This converter handles both systems properly. Switch between bytes, kilobytes, megabytes, gigabytes, terabytes and petabytes, choose base-10 or base-2, and get an accurate result for file sizes, cloud storage quotas, hosting limits and bandwidth figures. The page spells out both definitions for every unit, so you can see exactly which convention a number uses.
Developers and IT professionals use it for capacity planning, content creators for upload and export sizes, and students for coursework. Fast and mobile-friendly. Free, with no sign-up.
Base-10 counts in 1,000s (1 KB = 1,000 bytes) and is used by storage manufacturers; base-2 counts in 1,024s and is used by operating systems. This converter does both — pick the one your context uses.
Bytes, kilobytes, megabytes, gigabytes, terabytes and petabytes — 10+ digital units in the tool overall.
