Convert programmer bases
Use base conversion, binary, decimal, hex, and octal tools for quick code/math checks.
Convert common developer and IT formats: binary to decimal or hex, binary to text, text to ASCII/Unicode codes, storage units, and IPv4 address formats.
Educational conversion utilities only — values stay in the browser and are not saved or sent.
Use base conversion, binary, decimal, hex, and octal tools for quick code/math checks.
Turn binary into text, or text into ASCII/Unicode decimal, hex, and binary values.
Switch between bits, bytes, decimal storage units, and binary IEC units like GiB and TiB.
Search by goal, topic, or unit. Results update locally in your browser.
These are the calculators people are most likely to need first.
Use this shelf to translate values between digital formats such as binary, decimal, hex, text, Unicode, IPv4, and data-size units.
Start with the representation you have, then pick the converter that exposes bytes, code points, bases, or storage units in the form you need.
Check encoding, signedness, byte boundaries, separators, endian assumptions, and whether the destination expects readable text or raw values.
Suggested workflow: A safer digital workflow is: convert a small known sample, inspect the breakdown, then convert the full value once the format is confirmed.
Convert whole numbers between bases 2 through 36.
Switch between binary, decimal, hexadecimal, and octal.
Decode 7-bit or 8-bit binary groups into readable ASCII-style text.
Encode text as binary, decimal codes, hex codes, and Unicode code points.
Convert bits, bytes, KB, MB, GB, TB, KiB, MiB, GiB, TiB, and PiB.
Convert IPv4 addresses between dotted decimal, integer, binary, and hex.
