Hex / Binary — FAQ
Is anything uploaded to a server?
No. Everything runs locally in your browser.
Why does a decode fail?
Input must be valid hex (pairs of 0–9a–f) or valid 8-bit binary groups. Invalid chunks can’t be decoded.
Uppercase vs lowercase hex — does it matter?
No. A–F and a–f are equivalent.
