Binary Converter - Hex, Octal Prince Prempeh מאת

Binary Converter puts a full number-base toolkit one click away in your toolbar — no page to open, nothing to upload, no account.

★ Convert in any direction Text ⇄ Binary ⇄ Decimal ⇄ Hexadecimal ⇄ Octal. Pick a "From" and "To" format and it converts as you type. UTF-8 safe, so emoji and accented text survive the round trip.

★ Base converter Type a number once and see it in binary, decimal, hex, and octal at the same time. Exact for very large numbers.

★ Binary calculator Add, subtract, multiply, or divide two binary numbers. Results shown in both binary and decimal.

★ Private by design Everything runs locally in your browser. No servers, no network access, no analytics, no tracking. Your input never leaves your device — the extension requests zero permissions.

★ Light & dark theme Matches your system, or toggle it yourself.

Built by the team behind binaryconverter.net — the free binary translator used by students, developers, and anyone decoding a message.
