About this tool, examples & FAQ
Convert ASCII and UTF-8 text into 8-bit binary strings (Base2) or translate binary sequences back into readable text. Configure custom byte separators (spaces, commas, hyphens) with 100% private in-browser processing.
Key facts
| Byte Format | Standard 8-bit byte representation |
|---|---|
| Delimiters | Space, comma, hyphen, or contiguous binary stream |
| Maximum Input | 5 MB |
| Execution Deadline | 2 s |
How to use
- Paste your text or binary bit sequence into the input editor.
- Choose operation: Text to Binary or Binary to Text.
- Select your preferred byte delimiter (space, comma, hyphen, or none).
- Click Run (or press Ctrl/Cmd + Enter) to process the conversion via a local Web Worker.
- Copy or download the output string.

Hello WorldEdge cases
Incomplete 8-bit byte sequences
Standard character decoding requires complete 8-bit bytes. If a binary input string has a length that is not a multiple of 8, the validator alerts you to the exact number of trailing bits.
Whitespace and delimiter tolerance
When decoding binary to text, spaces, tabs, commas, hyphens, and line breaks are automatically stripped out so copied debug logs decode cleanly.
Multi-byte UTF-8 characters and emoji
International characters and emojis are represented by their constituent multi-byte UTF-8 byte sequences (e.g. 2, 3, or 4 bytes per symbol).
How it works
- Encodes input characters into raw UTF-8 byte streams using TextEncoder.
- Converts each byte into an 8-digit binary string with zero padding.
- Joins the 8-bit bytes with the chosen delimiter.
- Decodes binary streams by chunking into 8-bit segments and decoding UTF-8 bytes.

Frequently asked questions
How does text to binary translation work?
Each character maps to a numeric code point under UTF-8/ASCII. That number is converted into base 2 (zeros and ones) and padded to 8 bits.
Can this tool decode binary strings without spaces?
Yes. The decoder automatically handles unseparated binary streams as well as spaced or comma-separated lists.
Is my input saved or tracked?
No. All translation happens client-side in your web browser. No inputs or converted texts are logged or sent to servers.
