Free Online Encoders
Sometimes you need text in another representation: hex bytes for a protocol payload, binary for teaching or testing, ASCII or decimal codes for embedded systems, octal for legacy formats, or Morse code just for fun. These encoders convert any string instantly, character by character, with standard, predictable output — two-digit hex pairs, 8-bit binary groups, space-separated code values.
They are the mirror image of our decoding tools, so you can round-trip data in both directions while debugging. Everything runs client-side in your browser: free, instant, no accounts, and nothing you type is ever uploaded.

Launch ToolFrequently Asked Questions
- Do these encoders handle non-English text?
- They encode the UTF-16 code unit of each character, so accented and non-Latin characters still convert — characters above U+00FF just produce more than one byte or nibble of output, which is expected, not an error.
- What's Morse code actually useful for today?
- Mostly amateur radio, puzzle and CTF content, and teaching signal encoding — the translator maps standard International Morse Code letter by letter.
