Binary Translator

Overview

Use this binary translator when you need an explicit text-to-binary or binary-to-text conversion without encoding guesses. Choose UTF-8 or ASCII, select the exact byte separator, and copy a strict result that never treats long bit groups as Unicode code points.

Best for

• Converting ordinary text and emoji to their real UTF-8 byte representation.
• Encoding or decoding strict 7-bit ASCII data as 8-bit bytes.
• Checking space-separated, continuous, or line-separated binary byte sequences.

Not for

• Converting arbitrary integers, floating-point values, executables, files, Base64, hexadecimal, or octal.
• Encryption, decryption, security analysis, or guessing an unknown character encoding.

How it works

1. Choose Text to Binary or Binary to Text, then select UTF-8 or ASCII.
2. Choose whether bytes are separated by spaces, new lines, or no separator.
3. Enter the source, review the byte and bit counts, then copy or swap a valid result.

Limits and privacy

Every binary byte must contain exactly 8 bits. Continuous input must be divisible by 8, invalid UTF-8 is rejected, and ASCII rejects characters or bytes above 127. The page handles up to 10,000 Unicode code points or 80,000 binary digits locally.

Common uses

• Inspect the UTF-8 bytes for a word, accented character, CJK character, or emoji.
• Decode a known sequence of 8-bit binary bytes with an explicit encoding.
• Verify whether a binary sequence is valid UTF-8 or strict ASCII before sharing it.

Useful facts

• UTF-8 represents some characters with multiple bytes, so one visible character does not always equal one 8-bit byte.
• Tiny Work Tools converts the source locally and excludes the entered text, binary output, bytes, and exact lengths from analytics.
