Frequently asked questions
Is text to hex reversible?
Yes — use "HEX TO TEXT" to convert the output back to the original text.
Does it handle accented letters and emoji correctly?
Yes. It encodes and decodes real UTF-8 bytes, so characters like á, ñ, €, and emoji work correctly — not just plain ASCII.
Is my text uploaded anywhere?
No. Everything runs locally in your browser in vanilla JavaScript — nothing you type ever leaves your device.
