Binary Hex Base Converter

Convert numbers between binary, octal, decimal and hex live.

Convert any number between binary, octal, decimal, and hex — live, as you type. Every base updates at once, with exact bitwise math and zero float drift.

Built for developers, engineering students, and anyone who works close to the metal, this app turns messy radix math into a fast, tap-friendly workspace. Type a value in any base and read all four at a glance in clean, monospaced, grouped digits.

WHAT YOU GET • Live four-base conversion — binary, octal, decimal, hex, all in sync • Bitwise lab — AND, OR, XOR, NOT and shifts on a tappable bit grid • Developer reference — full ASCII table, powers of two, common masks, two's-complement explainer • Saved history — scroll back to values you converted earlier • Monospaced, grouped digits that stay readable at any width

HOW IT WORKS

1. Pick a base — bin, oct, dec, or hex
2. Type or tap in your value
3. Read every representation instantly, then flip bits in the lab

100% on-device. No accounts, no ads, no tracking — your numbers never leave your phone.

Full access — including the bitwise lab, the developer reference, and unlimited saved history — comes with Premium, available as a weekly or yearly plan or a one-time lifetime unlock.
