Binary Translator
Translate text into 8-bit binary or decode binary back into readable text. Full UTF-8 support, nothing uploaded.
How the binary translation works
Computers store text as numbers, and this binary translator shows you those numbers. In Text to Binary mode, each character is encoded as UTF-8 and written out as 8-bit groups separated by spaces, so a capital A becomes 01000001. In Binary to Text mode, those same 8-bit groups are read back into characters. If a group is the wrong length or contains anything other than 0s and 1s, you get a friendly note instead of a broken result. It all happens locally, so nothing you paste leaves your device.
A memory for the snippets you convert
Conversions pile up fast: a string here, a payload there, all of it gone the moment you close the tab. Relic keeps an end-to-end encrypted, searchable history of everything you copy, on every device, for as long as you want it. The translator is free, and your copied results never have to vanish again.
Frequently asked questions
How do I convert text to binary?
Type or paste your text in Text to Binary mode. Each character is encoded as UTF-8 and written as 8-bit groups separated by spaces, so a capital A becomes 01000001. Copy the result in one click.
How do I convert binary back to text?
Switch to Binary to Text mode and paste your binary in groups of 8 bits separated by spaces. The tool reads each byte back into a character. If a group is the wrong length or contains anything other than 0s and 1s, you get a note pointing at the problem instead of a broken result.
Why is binary written in groups of 8?
Eight bits make one byte, and one byte is the standard unit for a character in UTF-8 (for basic Latin text). Grouping by 8 keeps each byte visually separate, which is why this tool pads every group to 8 digits and expects the same when decoding.
Does this handle emoji and accented characters?
Yes. Text is encoded as UTF-8 before conversion, so characters outside plain ASCII (accents, emoji, non-Latin scripts) become multiple bytes, meaning more than one 8-bit group. Decoding reads those multi-byte sequences back correctly.
Is my text sent anywhere when I convert it?
No. The conversion runs entirely in your browser, so nothing you paste is uploaded. You can safely convert text that contains private data.
