To convert text to binary manually, look up each character's numeric code, then write that number in base 2. In ASCII, every character has a decimal value — capital "A" is 65 — which you convert to binary by repeatedly dividing by 2 and reading the remainders from bottom to top, giving 01000001. Each ASCII character becomes exactly eight bits (one byte), so you repeat the process for every letter and join the bytes with spaces. For example, "Hi" is 01001000 01101001. The tedious parts are remembering the code table and doing the division without slips. This converter does both instantly for any length of text, and its step-by-step breakdown actually shows the code point, the division remainders, and the final binary so you can check the math rather than just trust the result.

ASCII uses a fixed seven bits stored in one byte per character, so it can only represent 128 symbols — plain English letters, digits, and basic punctuation. UTF-8 is variable-width: common Latin characters still take one byte and match ASCII exactly, but accented letters like "é" use two bytes, most symbols and many scripts use three, and emoji use four. So a word that looks short can occupy far more bytes than its character count suggests once non-English characters appear. That mismatch is why a name with an accent seems to "take up more space" than expected. This tool lets you switch between ASCII, UTF-8, and UTF-16 and reports the exact byte and bit totals for each, so you can see precisely how your encoding choice changes the output size before it hits a database field or length limit.

They are four ways of writing the same byte values in different number bases. Binary (base 2) uses only 0 and 1, so a byte is eight digits like 01000001. Hexadecimal (base 16) uses 0-9 and A-F, packing that same byte into two compact digits, 41 — which is why programmers prefer hex for memory and color codes. Octal (base 8) groups bits in threes and shows 101. Decimal (base 10) is the everyday value, 65. None changes the underlying data; they are just notations, and you can convert between them freely. This converter outputs all four bases and can add prefixes like 0b, 0x, and 0o so the notation is unambiguous. Pick the base you need from the options, and the character map lists each letter's decimal, hex, octal, and binary side by side.

Decoding reverses the process: you split the binary into byte-sized groups, convert each group back to its numeric value, then look that number up in the character table. With standard ASCII or single-byte UTF-8, that means slicing the digits into chunks of eight — 01001000 01101001 becomes 72 and 105, which map to "H" and "i." The catch is knowing how the bits were grouped and which encoding produced them, since multi-byte UTF-8 characters span several bytes. This tool handles all of that for you: paste the binary, choose the matching encoding, and it returns the original text. An auto-detect option even reads pasted input and guesses whether it is binary, hex, octal, or decimal, so decoding usually just works. You can also adjust the bit grouping and separator if your binary uses a different format.

A bit is a single binary digit — one 0 or one 1 — and eight bits make one byte. So a string of pure ASCII text uses exactly one byte, or eight bits, per character: a 10-character message is 80 bits. With variable-width UTF-8 the count rises whenever accented letters, symbols, or emoji appear, since those characters consume two to four bytes each. Counting by hand is easy to get wrong once mixed characters are involved, which matters when you need to fit a string inside a fixed database column, a protocol field, or an encoding assignment. The statistics panel in this converter does the arithmetic automatically, reporting total characters, byte count, and bit count, and it flags the extra overhead added by multi-byte characters. Type or paste your text and the totals update instantly as you go.
