Frequently asked questions
Does the hex input need a 0x prefix on each byte?
No — plain hex digits like "48 69 21" work fine. If your input already has 0x prefixes or extra spacing, those are stripped automatically before decoding.
Is my text uploaded anywhere?
No — Convertisseur hexadécimal vers texte runs entirely in your browser using JavaScript/WebAssembly. Your text is never sent to a server.
What happens if I paste an odd number of hex digits?
It's reported as invalid — each byte needs exactly two hex digits, so an odd-length string is missing or has an extra digit somewhere and can't decode reliably.
