Frequently Asked Questions

How does binary work?
Binary is a base-2 number system using only 0 and 1. Each text character is represented by its ASCII code converted to 8 binary digits (bits). For example, "A" is 65 in decimal, which is 01000001 in binary.
What is the difference between binary, hex, and octal?
Binary uses base 2 (digits 0-1), octal uses base 8 (digits 0-7), and hexadecimal uses base 16 (digits 0-9 and A-F). They are all different ways to represent the same numbers.
Why is each character 8 bits?
Standard ASCII uses 7 bits (0-127) to represent characters, but it is conventionally stored in 8 bits (a byte) for alignment. Extended ASCII and UTF-8 use 8 or more bits per character.
Can I convert binary back to text?
Yes, switch to Binary to Text mode and paste space-separated 8-bit binary values. The tool will decode each byte back to its corresponding text character.
Does it support Unicode?
The tool converts characters based on their Unicode code points. Basic ASCII characters (0-127) work with 8-bit representation. Characters above 127 may require multiple bytes.

About Binary

What this tool does

Encoder and decoder tools convert data between Base64, URL-encoded, HTML entities, ROT13, Morse code, binary, hex, and JWT formats. They handle both encoding (plain to encoded) and decoding (encoded back to plain).

Why use this tool

Web developers constantly encounter encoded data in APIs, URLs, tokens, and configuration files. Being able to decode a JWT payload or Base64 string instantly saves round-trips to the terminal or Stack Overflow.

How it works

Each tool applies a specific encoding algorithm to your input bytes. Base64 maps every 3 bytes to 4 ASCII characters. URL encoding escapes special characters with percent-hex pairs. JWT decoding splits the token at dots and Base64-decodes each segment.

Pro tip

When debugging JWTs, always check the "exp" (expiration) claim first. Most authentication bugs come from expired tokens, and the decoded timestamp is easy to overlook.
