Convert text and bytes between UTF-8, hexadecimal and binary.

Use the guide alongside the working tool.

Working input

Hello 🌍

Convert text and bytes between UTF-8, hexadecimal and binary. UTF-8 decoding is strict. Hex requires complete byte pairs and binary requires 8-bit groups. No guessed text encoding or silent replacement characters.

Input and purpose

Convert text and bytes between UTF-8, hexadecimal and binary.

Start with the working sample, then replace it with your own input. The sample input is: Hello 🌍

Review the result

UTF-8 decoding is strict. Hex requires complete byte pairs and binary requires 8-bit groups. No guessed text encoding or silent replacement characters.

Run processes the current input on your device. Changing an input clears the previous output so you cannot accidentally export stale results.

Copy and export

Copy or download only after reviewing the exact generated text. Nothing is applied to your project or sent to an endpoint.

Use Undo sample to restore your draft. Clear inputs or close the tab when finished; no content is stored in localStorage.
