二进制转换器

概述

Binary is the base-2 number system computers use, where every character is stored as a sequence of 0s and 1s. This translator converts plain text to binary and back, making it easy to see how letters map to their underlying byte values. It runs entirely in your browser.

使用步骤

1. 1

   Enter text or binary

   Type text to encode, or paste 0s and 1s to decode.

2. 2

   Pick the direction

   Choose text-to-binary or binary-to-text.

3. 3

   Copy the result

   The converted output appears instantly for you to copy.

工作原理

Each character is mapped to a number via its character code (ASCII or Unicode), and that number is written in base-2, usually as an 8-bit byte. For example, the letter A is 65, which is 01000001 in binary. Decoding reverses the process: each 8-bit group becomes a number, which maps back to a character.

什么时候用

Learning how computers represent text. Completing a homework or class exercise on number systems. Encoding a short message as binary for fun or a puzzle.
