Binary Translator

Binary Translator. Translate binary to text online — free binary translator and decoder that can also encode text back to binary, with multiple delimiter options. Instantly translate binary to text with our free online binary translator.

Paste a binary sequence to decode it into readable characters, or switch modes to turn text into binary. Supports multiple delimiters — space, comma, dash, or no separator — for maximum flexibility.

Our binary decoder handles ASCII and Unicode characters accurately, making it ideal for computer science students, developers, and anyone working with binary data formats.

Our binary to text converter runs entirely in your browser — no data is ever uploaded to a server. All conversion happens locally, so your text and binary sequences stay completely private.

Results update instantly as you type, and you can copy or download the output with one click. Whether you need to decode binary strings or occasionally encode text into binary, the swap button reverses direction in one click.

For a dedicated encoder with more output options, see our Text to Binary converter.

Frequently asked questions

How do I convert binary code to text?

Select Binary to Text and paste the binary, for example 01001000 01101001. Bytes can be separated by spaces, commas or dashes, or written without separators. The Text output shows Hi, and you can copy it or download it as a .txt file.

How do I convert text to binary?

Keep Text to Binary selected and type your text. Each UTF-8 byte of the text is written as 8 bits, separated by the chosen delimiter, so A becomes 01000001. Swap direction moves the result into the input and reverses the conversion.

What does the Delimiter option do?

It sets the separator placed between bytes when encoding: Space, Comma, Dash or None. When decoding, any of these separators is recognised automatically. Groups of up to 8 bits count as one byte, and longer groups must be a multiple of 8 bits, otherwise you see Invalid binary input.

Does the binary translator support emoji and non-English characters?

Yes. Text is encoded as UTF-8, so é becomes 11000011 10101001 and an emoji becomes four bytes, with every delimiter including None. Binary to Text decodes UTF-8 back to the original characters; byte sequences that are not valid UTF-8 show the replacement character.

Is my text sent to a server?

No. The conversion runs in your browser as you type, and the Download button creates the text file locally.

How to use this online tool

Binary Translator is designed for fast browser workflows when you need to format, validate, convert, decode, encode, generate, or inspect data without opening a heavy desktop app. Start with the input field or visible options, review the result, then copy or download the output for the next step.

Private processing in your browser

Binary Translator keeps the normal processing step local in your browser. That is useful for code snippets, tokens, documents, configuration values, text samples, and other material that should not be sent to a remote service unless you explicitly choose to share it.

When this tool is useful

Use Binary Translator for repeatable developer tasks, technical documentation, QA checks, quick conversions, debugging, content cleanup, and internal team workflows. The page focuses on clear inputs, immediate feedback, and output that is easy to reuse in code, reports, tickets, emails, or notes.

Practical tips

Before copying the final result, check important details such as spacing, casing, filenames, encoding, token structure, line breaks, or output format. Small checks prevent mistakes when the result is reused in source code, API requests, documentation, spreadsheets, or shared files.
