A text to binary converter encodes any text string into its binary (base-2) representation by converting each character to its UTF-8 byte values and then representing each byte as an 8-bit binary number. For example, the letter A becomes 01000001. This tool also shows hex and octal equivalents and supports converting binary back to readable text.
How to Convert Text to Binary
The text to binary converter translates characters into their underlying byte values expressed in base-2 (binary). Each character in your text maps to one or more bytes, and each byte is represented as an 8-bit binary number padded with leading zeros if needed. The letter H is ASCII 72, so it appears as 01001000 in binary.
Text to Binary Mode
Type or paste any text — including Unicode characters, emoji, and non-Latin scripts — into the input box. The converter uses the browser's TextEncoder API to get the exact UTF-8 bytes for every character, then converts each byte to an 8-bit binary group. The separator option controls whether groups are separated by spaces, nothing, or a custom character. You also get the hex and octal equivalents simultaneously.
Binary to Text Mode
Switch to Binary → Text mode and paste your binary string. The tool accepts space-separated groups (e.g., 01001000 01101001) or a continuous string of 1s and 0s chunked into 8-bit bytes. It uses TextDecoder to reconstruct the original text, correctly handling multi-byte Unicode characters.
Understanding the Hex and Octal Views
The hex output shows the same byte values in base-16, which is more compact — one byte fits in exactly 2 hex digits. The letter A (binary 01000001) is 41 in hex. Hex is widely used in programming, color codes, and memory addressing. Octal (base-8) is less common today but still appears in Unix file permissions (e.g., chmod 755).
FAQ
Is this text to binary tool free?
Yes, the text to binary converter is completely free with no account required. Convert text and binary instantly with no limits.
Is my text data private?
Yes. All conversion happens entirely in your browser using JavaScript. Your text is never sent to any server.
How is this different from the Binary Converter tool?
The Binary Converter translates numbers between bases (e.g., decimal 42 to binary 101010). This tool converts text strings — like the word 'Hello' — into the binary representation of each character's byte values. The result for 'A' is 01000001 (ASCII code 65 in binary).
Does this support Unicode and emoji?
Yes. The converter uses the TextEncoder API to get the actual UTF-8 bytes for any Unicode character, including emoji and non-Latin scripts. Each byte is then converted to 8-bit binary. A single emoji may produce multiple binary groups since emoji often use 3-4 bytes in UTF-8.
What does '01000001' mean in binary to text?
01000001 is 65 in decimal, which is the ASCII code for the letter 'A'. Binary to text works by splitting your binary input into 8-bit chunks, parsing each as a decimal number, then decoding those bytes as UTF-8 text using TextDecoder.
What separator should I use?
Use a space separator (default) for readability — each byte group is separated by a space. Use 'none' to get a continuous binary string. When converting binary back to text, the tool accepts both space-separated and continuous 8-bit-chunked binary strings.
Why are there hex and octal outputs too?
Hex and octal are common alternative encodings used in programming. Hex (base-16) is used in color codes, memory addresses, and encoding standards. Octal (base-8) appears in Unix file permissions. All three views show the same underlying byte values in different number bases.
