Binary to Text Converter

Decode binary code back to readable text. Accepts bytes separated by spaces, commas or new lines, pads short groups and validates UTF-8. Free, runs locally.

Binary (0 and 1)

Decoded text (UTF-8)

Hi!

Spaces, commas and line breaks between bytes are ignored. Groups shorter than 8 bits are left-padded with zeros; ungrouped input must be a multiple of 8 bits.

What is Binary to Text?

Paste a sequence of 0s and 1s and get the text it encodes. The bytes are decoded as UTF-8, so accented letters, non-Latin scripts and emoji come out correctly, and invalid byte sequences are reported instead of producing garbage.

How to use Binary to Text

Paste binary into Binary (0 and 1); bytes may be separated by spaces, commas or line breaks.
Read the decoded text in Decoded text (UTF-8).
If an error appears, check for stray characters or a missing digit.

When to use Binary to Text

Use it to read binary messages, homework answers or byte dumps. It does not decode other encodings such as UTF-16, Latin-1 or Base64 – convert those with a dedicated tool.

How Binary to Text works

Separators are stripped and every remaining character must be 0 or 1. When the input is split into groups of up to 8 digits, each group is one byte (shorter groups such as 7-bit ASCII are left-padded with zeros). Without separators the bit string is cut into 8-bit bytes and must therefore be a multiple of 8 long. The bytes are passed to TextDecoder in fatal UTF-8 mode, which rejects invalid sequences.

Common Use Cases

Decode a binary message from a puzzle or game
Check the result of a text-to-binary exercise
Read 7-bit ASCII binary written without leading zeros
Verify that a byte sequence is valid UTF-8

FAQs

Why do I get "not a whole number of bytes"?

Without separators the converter cuts the input into 8-bit bytes. If the total length is not a multiple of 8, a digit is missing or extra; add spaces between bytes so each group is read on its own.
