Full UTF-8 support, nothing uploaded. Runs entirely in your browser. Nothing you type is uploaded. Plain text Try Binary output Result appears here… ## 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 and the word Hi becomes 01001000 01101001\. In **Binary to Text** mode, those same groups are read back into characters. Swap moves the result into the box so you can send it straight back the other way. It all happens locally, so nothing you paste leaves your device. ## Emoji and accented letters Plain English letters are one byte each, so one character gives you one 8-bit group. Accented letters and emoji take more than one byte in UTF-8, so é becomes two groups and ☕ becomes three. The line under the result tells you how many characters and how many bytes you are looking at, and decoding puts the multi-byte characters back together exactly as they were. ## What the decoder accepts * 8-bit groups separated by spaces, tabs, line breaks or commas. * A run of bits with no separators at all, as long as it is a whole number of bytes. * Groups written with a 0b prefix, like 0b01001000. Anything else gets a plain note instead of a broken result: it names the group that is not made of 0s and 1s, says how many bits a short group has, points at the leftover bits when a long run does not divide into bytes, and tells you when the bytes are not valid UTF-8 text. ## 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. Groups of 8 bits separated by spaces are the usual shape, and tabs, line breaks and commas work too. A 0b prefix is ignored, and a long run of bits with no spaces at all is split into bytes for you as long as it divides evenly by 8\. The tool reads each byte back into a character, and 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, and the line under the result shows the character count next to the byte count. What is a binary translator useful for?+ Learning how computers store text, classroom exercises, and puzzle or CTF challenges where a message is hidden as ones and zeros. It is also a quick way to check what a string really is byte for byte. Swap sends the result back the other way, so you can confirm a round trip in one click. Is my text sent anywhere when I convert it?+ No. Both directions run entirely in your browser, so nothing you paste is uploaded. You can safely convert text that contains private data. You just copied that. What if you never lost it? **Relic** remembers everything you copy, forever, searchable on every device, and end-to-end encrypted so only you can read it. 250 MB free [Download forWindows](https://relic.space/download/windows)[Download formacOS](https://relic.space/download/macos)[Download forLinux](https://relic.space/download/linux)[Download forAndroid](https://play.google.com/store/apps/details?id=relic.space.app&referrer=utm%5Fsource%3Drelic.space%26utm%5Fmedium%3Dwebsite%26utm%5Fcampaign%3Dcontent)[Download foriPhone](https://apps.apple.com/us/app/relic-clipboard-vault/id6800556025) More free tools [Morse Code Translatormorse code translator](https://relic.space/tools/morse-code-translator)[Caesar Ciphercaesar cipher](https://relic.space/tools/caesar-cipher)[ROT13rot13](https://relic.space/tools/rot13)[Vigenère Ciphervigenere cipher](https://relic.space/tools/vigenere-cipher)[Atbash Cipheratbash cipher](https://relic.space/tools/atbash-cipher)[ASCII Art Generatorascii art generator](https://relic.space/tools/ascii-art-generator)[All tools](https://relic.space/tools)
