About Binary Encoder

Binary Encoder is a free online tool that converts text characters into their binary (base-2) representation. Each character is converted to its UTF-8 byte value and displayed as an 8-bit binary number. This is useful for understanding how text is stored in computers, debugging data encoding issues, and learning about binary number systems.

The tool supports full Unicode and UTF-8 characters, so it correctly handles text in any language, emojis, and special characters. Multi-byte UTF-8 characters produce multiple 8-bit binary groups. All processing happens entirely in your browser — no data is sent to any server.

Frequently Asked Questions

What is Binary Encoder? expand_more
Binary Encoder is a free online tool that converts text into binary representation. Each character is converted to its UTF-8 byte values and displayed as 8-bit binary numbers (0s and 1s). For example, the letter A (ASCII 65) becomes 01000001.
How does it handle Unicode characters? expand_more
The tool uses UTF-8 encoding, so multi-byte characters like emojis or non-Latin scripts produce multiple 8-bit binary groups. For example, a 2-byte character produces two 8-bit binary groups, and a 4-byte emoji produces four groups.
Is my data secure? expand_more
Yes. All encoding happens entirely in your browser using JavaScript. No data is sent to any server, ensuring your text remains completely private and secure.
What does the Space/No Space option do? expand_more
The Space option inserts a space between each 8-bit binary group, making the output easier to read and separate into individual bytes. The No Space option outputs a continuous stream of 0s and 1s without any separators.
