Data Size Converter

Convert between bits and bytes and every decimal (kB, MB, GB) and binary (KiB, MiB, GiB) multiple, with 1 byte = 8 bits.

This tool handles input and primary processing in your browser and is designed not to send the input to QuickKit’s server.

How it works

Decimal units step by 1000 (kB, MB, GB, TB, PB); binary units step by 1024 (KiB, MiB, GiB, TiB, PiB). Bits use lowercase 'b', bytes use uppercase 'B'. Very large or very small results switch to scientific notation, and values above 2^53 are approximate because they exceed exact floating-point range.
