What is pretty-bytes?
pretty-bytes is a JavaScript utility that converts numeric byte values into human-readable strings like '1.34 kB' or '1 KiB'. It solves the problem of presenting raw byte counts in a format that's easily understandable by users, with support for different unit systems and localization.
Developers building applications that need to display file sizes, memory usage, network transfer rates, or any byte-based metrics in a user interface.
Developers choose pretty-bytes for its robust feature set—including bit formatting, binary/SI prefixes, localization, and fixed-width alignment—coupled with sensible defaults that avoid common pitfalls like misleading rounding.
