[Online Tool] Binary and Hex Converter — Convert Between Any Base from 2 to 36

"What is 0xFF in decimal?"

"What does 11111111 in binary convert to?"

"What base are the numbers in a color code like #1A2B3C?"

These questions come up constantly in programming, hardware debugging, network configuration, and color work. Mental arithmetic takes time; reaching for a calculator breaks your flow. A dedicated base conversion tool is the smoothest solution.

Toolshu's Online Base Converter supports conversion between any bases from 2 to 36. Enter a number, select the source base and target base, and the result appears instantly.

The Four Most Common Bases — Clarified

Binary (Base 2): Uses only 0 and 1 — the language of hardware. All data is stored and processed in binary at the hardware level. The binary number 1010 equals 10 in decimal.

Octal (Base 8): Uses digits 0–7. Common in Unix/Linux file permissions — the 755 in chmod 755 is an octal value.

Decimal (Base 10): The everyday number system using 0–9. No further explanation needed.

Hexadecimal (Base 16): Uses digits 0–9 plus letters A–F — 16 characters total. Memory addresses, color codes (#FF5733), and byte data all use this format. FF in hex equals 255 in decimal — which is why each RGB channel has a maximum value of 255.

Why Is Hexadecimal So Ubiquitous?

Because the conversion between hex and binary is remarkably clean: exactly 4 binary digits correspond to exactly 1 hexadecimal digit.

For example, binary 1111 1111 splits into two groups: 1111 (= 15 = F) and 1111 (= 15 = F) — combined, that's FF in hex.

This neat correspondence makes hexadecimal the standard shorthand programmers use to read and represent binary data. Writing FF is far more practical than writing 11111111 — with zero information lost.

What's the Point of Supporting Up to Base 36?

The tool covers bases 2 through 36 — 36 being the natural ceiling, since digits 0–9 plus letters A–Z give exactly 36 distinct characters.

Base 36 has seen real-world use in early URL shorteners and certain encoding systems where compressing string length mattered. Base 32 appears in some hashing and encoding contexts as well. Most of the time you won't need bases this high — but when you do, the tool handles it without needing to look elsewhere.

Pair It with the Timestamp Converter

Development work often surfaces hex timestamps or other data that needs base conversion. Toolshu also has an Online Timestamp Converter: https://toolshu.com/en/timestamp — for converting between Unix timestamps and human-readable datetime. The two tools complement each other well for debugging sessions.
