How do I convert text to binary?

Paste your text and each character becomes an 8-bit value. Example: A is ASCII 65 → 01000001.

What encoding does this use?

ASCII/UTF-8. Basic English letters are one byte; accented characters and emoji may use multiple UTF-8 bytes.

Can I decode binary back to text?

Yes. Paste bits with or without spaces and switch to decode mode.

Why is each character 8 bits?

One byte (8 bits) covers 0–255 and keeps output aligned for decoding. UTF-8 characters outside basic ASCII span multiple bytes.

No. Conversion runs entirely in your browser. Related tools: Base64 Encoder / Decoder and UUID Generator.

About Text to Binary Converter

Convert any text to 8-bit binary, or paste 0s and 1s to decode back to text. Uses ASCII/UTF-8 so letters, spaces, and most Unicode characters work — including accented text and emoji. Nothing leaves your device.

How to Use Text to Binary Converter

Paste text to encode it as binary.
Or switch to decode mode and paste binary (with or without spaces).
Each character becomes an 8-bit group, spaced for readability.

Text to Binary Converter Formula

Each character maps to its Unicode code point, then to binary. Example: H = 72 → 01001000. Multi-byte UTF-8 characters become multiple 8-bit groups. Spaces between bytes are only for reading — decoding accepts spaced or continuous bits.

Text to Binary Converter Examples

Hello

01001000 01100101 01101100 01101100 01101111

Letter A

A → 01000001 (ASCII 65)

Decode

01001110 01101111 → No
