Convert byte counts to human-readable strings and back, with formatting options.

Installation

pip install philiprehberger-humanize-bytes

Usage

from philiprehberger_humanize_bytes import format_bytes, parse_bytes

Formatting bytes

format_bytes(1536)          # "1.5 KiB"
format_bytes(1048576)       # "1 MiB"
format_bytes(0)             # "0 B"
format_bytes(-1536)         # "-1.5 KiB"

SI units (base 1000)

format_bytes(1500, si=True)           # "1.5 KB"
format_bytes(1000000, si=True)        # "1 MB"
format_bytes(2500000000, si=True)     # "2.5 GB"

Custom precision

format_bytes(123456789, precision=2)  # "117.74 MiB"
format_bytes(123456789, precision=0)  # "118 MiB"

Parsing byte strings

parse_bytes("1.5 GB")    # 1500000000
parse_bytes("1.5 GiB")   # 1610612736
parse_bytes("500 KB")     # 500000
parse_bytes("10M")        # 10000000
parse_bytes("1024")       # 1024

API

Function	Description
format_bytes(n, *, si=False, precision=1)	Format byte count to human-readable string. Binary (KiB/MiB/GiB) by default, SI (KB/MB/GB) with si=True.
parse_bytes(s)	Parse a human-readable byte string to an integer. Supports binary, SI, and shorthand units. Case-insensitive.

Development
