Binary Translator

Key features

• Encode mode shows all four bases simultaneously — 8-bit padded binary, 3-digit octal, 2-digit uppercase hex, decimal — each with its own copy button.
• Decode mode takes a source base selector (2, 8, 10 or 16) and rebuilds the original text.
• Flexible parsing: bytes separated by spaces, commas or semicolons — or a continuous binary/hex/octal string, chunked automatically by fixed width.
• Strict UTF-8 decoding flags invalid byte sequences with a specific error instead of printing mojibake.
• Unicode-safe: emoji and non-Latin scripts encode into their true multi-byte UTF-8 sequences.
• Stat tiles track input characters, input UTF-8 bytes and output length.

How it works

1. 1

   Choose encode or decode

   The Encode tab converts text into byte notations; the Decode tab turns byte strings back into text.

2. 2

   Encoding: type any text

   Enter plain text — try the example button for 'Hello 👋' — and all four base representations fill in live, byte per byte.

3. 3

   Decoding: pick the source base

   Select which base your input uses, then paste the bytes. Separators are optional for fixed-width bases; decimal needs spaces between values.

4. 4

   Copy the result

   Each encoded base has a copy button, and the decoded text panel gets its own — errors, when they occur, explain exactly what's wrong.

Tips for better results

• 💡Emoji become 4 UTF-8 bytes, which is why 'Hello 👋' makes 9 bytes — that's correct, not a bug.
• 💡A continuous run like 0100100001101001 is accepted: it's chunked into 8-digit bytes automatically (2 digits for hex, 3 for octal).
• 💡Decimal decode needs spaces between numbers — the tool says so explicitly if you paste a run of digits.
• 💡Hex input is case-insensitive, but the tool outputs uppercase two-digit pairs for easy comparison.
