Binary Translator

No. All translation logic runs in your browser using JavaScript. The tool performs string and arithmetic operations client-side using the browser's built-in String.fromCharCode(), parseInt(), and toString(2) functions. You can verify this by watching the Network tab in DevTools — the Translate button triggers no outgoing requests.

Each character is converted to its Unicode codepoint (a number), then that number is represented in base-2 (binary). For standard ASCII text, each character produces an 8-bit group (padded with leading zeros if needed). Groups are separated by spaces for readability. Binary-to-text reads each 8-bit group, converts it back to a decimal codepoint, and maps it to a character using String.fromCharCode().

By convention, binary representations of ASCII characters are padded to 8 bits (one byte) so they're all the same length. This makes it easier to read and split binary strings back into characters. Without padding, the letter A (65) would appear as 1000001 — hard to distinguish from 10000010 (the decimal 130) at a glance.

Hex mode accepts standard hexadecimal input with digits 0–9 and letters A–F (case-insensitive). You can enter a single value like FF or a space-separated sequence like 48 65 6C 6C 6F. The tool does not require a 0x prefix. Invalid hex characters trigger an inline error.

Yes — click the swap button (the double-arrow icon between the two panels) to reverse the direction. When swapped, the left panel accepts binary input and the right panel shows the decoded text, decimal, or hex value depending on your selected mode.

Binary input must contain only the digits 0 and 1, optionally separated by spaces. Any other character — including letters, commas, or dashes — triggers the inline validation error with a red border. This catches common mistakes like pasting hex values into binary mode.
