Text to Binary Converter
Convert text to 8-bit binary and binary back to text. UTF-8 aware, so any character round-trips correctly.
UTF-8, 8 bits per byte. Runs locally, nothing is uploaded.
About this tool
This converter turns text into binary and binary back into text. Each character is encoded as its UTF-8 bytes, and every byte is shown as eight bits, so the output matches how computers actually store the text. Decoding reverses it, accepting binary with or without spaces.
It runs entirely in your browser, so nothing you type is uploaded. Use it to learn how text maps to bits, to build test data, or to decode a binary string someone sent you.
Frequently asked questions
How is each character converted?+
The text is encoded as UTF-8 and each byte is written as eight bits. ASCII characters take one byte; accented characters and emoji take several.
Can I decode binary without spaces?+
Yes. Non-binary characters are ignored and the bits are read in groups of eight, so spaced or unspaced input both work as long as the total is a multiple of eight.
Is anything uploaded?+
No. The conversion happens entirely in your browser.
