Binary Translator

It maps text to binary one character at a time. Every letter, digit, or symbol has a number code, and the translator turns that code into an 8-bit binary byte, then joins the bytes with spaces so they're easy to read. Going the other way, it reads each group of 8 bits, turns it back into a code, and shows the character. It all happens right in the page, so you'll get the result instantly and nothing you type is sent anywhere.

Switch the direction to binary-to-text, paste your binary in, and the translator reads it back into words. It expects 8 bits per character, with or without spaces between the bytes, since that's how text is normally encoded. If a group isn't a clean 8 bits it'll do its best and flag anything odd. This is the quick way to decode a binary message someone sent you, or to check your own work.

Binary is base 2, so it uses only 0 and 1, where each place is worth twice the one to its right: 1, 2, 4, 8, 16, and so on. To read a binary number you add up the place values wherever there's a 1. The byte 01000001 is 64 plus 1, which is 65, the code for a capital A. Computers use binary because a circuit is either off or on, which lines up perfectly with 0 and 1.

Yes, the number-base box does that. Type a value into any of the four fields, binary, decimal, hexadecimal, or octal, and the other three update at once. It's handy when you're reading a color code, a memory address, or a permissions value and need it in another base. The text translator and the base converter sit on the same page, so you don't have to hunt for a second tool.

It does. Spaces, punctuation, and digits all have codes just like letters, so they translate cleanly in both directions. Standard English text works perfectly, and most common symbols do too. Very unusual characters and emoji use longer multi-byte codes, so they're best handled by a dedicated encoder, but for everyday messages and code snippets this translator has you covered.

Yes to both. There's no sign-up, no limit, and the whole thing works locally in your browser, so your text never leaves your device. Bookmark it for homework, a class on number systems, a coding project, or just decoding a fun binary message. You'll have your translation in a second, and you can copy the result with one tap whenever you need it.

English to binary is the same job as text to binary, since English words are just text. Keep the direction on text-to-binary, type your English words in the box, and each character turns into its 8-bit code, one byte per letter. To go back, flip the direction and paste the 1s and 0s. It's the fast way to turn any English message into binary, or read one you've been sent.

Each letter has its own byte, so a whole word is just those bytes in a row. Hello is 01001000 01100101 01101100 01101100 01101111 and Help is 01001000 01100101 01101100 01110000. Lowercase letters use different codes than capitals, so hi (01101000 01101001) and Hi (01001000 01101001) aren't the same in binary. The common-words table above lists a handful you can copy straight away, or just type your own word to see it live.
