Binary ↔ Text

Capital A is character code 65 in ASCII. Written in base 2, 65 is 1000001, and padding it to a full eight bits gives 01000001. Lowercase a is code 97, which encodes as 01100001, so case changes exactly one bit.

Eight, padded with leading zeros, for any character with a code up to 255. Characters beyond that range, like the euro sign or emoji, have larger code values and print with more than eight digits, since their number simply doesn't fit in one byte.

Not reliably. The decoder splits on whitespace, so an unbroken string like 0100100001101001 is treated as one giant number instead of two bytes. Insert a space after every eighth digit and the decode comes out correctly.

One of the space separated chunks contains a character other than 0 or 1, and the error names the offending chunk. Common culprits are the letter O standing in for zero, or stray punctuation copied along with the bits.

It encodes each character's code unit value, which matches ASCII exactly for English letters, digits, and standard punctuation. It does not emit UTF-8 multi-byte sequences for characters outside that range, so accented and non-Latin characters round trip here but won't match a UTF-8 byte dump.

Yes, every character gets encoded, including spaces. A space is code 32, or 00100000, and a period is code 46, or 00101110. That's why the output for a sentence is longer than you might expect.

Work the problem on paper first, then paste your bits here and press the decode button. If the text that comes back matches the original message, your padding and place values were right.

Paste your space separated bytes and press Binary → Text. To translate binary to text the tool reads each group of eight 0s and 1s, turns it into a character code, and prints the letter. So 01001000 01101001 comes back as Hi, no base 2 math by hand.

It maps each character to its numeric code and writes that code as eight bits, which lines up with ASCII for English letters, digits, and standard punctuation. That's the same encoding a computer uses for a single byte. Anything above code 255 needs more than eight bits, so it prints longer.

Yes. It's a text to binary converter online that runs in your browser with no signup and no upload. Type a word, press Text → Binary, and each letter becomes its eight bit code. Nothing you enter is sent anywhere, so it's fine for private notes.

Yes. It goes text to binary with one button and binary back to text with the other, so you can round trip a message and confirm nothing changed. As a binary code converter it validates every chunk on the way back and flags anything that isn't purely 0s and 1s.

Not as a separate column, no. It jumps straight from characters to eight bit binary, and the decimal code is the hidden middle step: A is 65, which is 01000001. If you want the decimal or hex spelled out, run the byte through a base converter too.

No, and it's worth clearing up. It swaps characters for their 0s and 1s; it doesn't translate between human languages. Binary is often called the language of computers, which is where the name comes from, but your words stay in whatever language you typed them.

Yes. Decode a full run of bytes and the letters join into words on their own, since each eight bit group is one character. So binary to words works fine as long as every byte is separated by a space. Missing spaces are the usual reason the output looks like gibberish.

It reads each eight bit group as a number and looks up that ASCII code. So binary to ascii is a direct lookup: 01000001 is 65, which is A. For codes 0 to 127 the result matches the standard ASCII table exactly.

Yes, both ways. It turns each character into eight bits, and pressing the other button takes binary to letters again. That round trip is handy for checking a worksheet: encode, decode, and confirm you land back on the original word.

Sure. Paste their 0s and 1s, keep a space between each byte, and press Binary → Text. It reads standard eight bit ASCII, so any message encoded the normal way comes back readable. If odd characters appear, check that each group is exactly eight digits long.

Type or paste your letters, then press Text → Binary. The tool encodes eight bits at a time, so HELLO becomes five space separated bytes. Each byte is the character's ASCII value written in base 2.
