How to Encode Text to Binary Online
Type or paste plain text into the box above and it converts to 8-bit binary instantly, with each character's binary byte separated by a space. This tool only encodes; if you need to decode a binary string back into text instead, use our dedicated Binary Decoder.
Example
Typing Hi encodes to 01001000 01101001 — each letter becomes its own 8-bit byte based on its ASCII value.
Common Use Cases
- Learning how computers represent text at the bit level.
- Creating a binary-encoded message for a puzzle, gift, or novelty project.
- Generating binary test data for programming exercises or homework.
FAQs
Why 8 bits per character?
8 bits (1 byte) can represent 256 values, enough to cover the standard ASCII character set used for basic English text and symbols.
Does this support special characters and emoji?
Each character is encoded using its underlying character code, so standard letters, numbers, and punctuation all encode correctly. Multi-byte characters like emoji may produce multiple binary bytes.
Does this tool also decode binary back to text?
This page is encode-only, for a simpler, focused experience. Use our separate Binary Decoder tool if you need to convert a binary string back into plain text.
