Considérations techniques et limites
- • Zero-transmission privacy: data processing runs strictly client-side inside your browser environment. Source code, secrets, and payloads are never dispatched to external servers or telemetry systems.
- • La vitesse de traitement dépend du matériel de votre appareil (processeur et mémoire RAM). Les fichiers de plus de 200 Mo peuvent dépasser la mémoire du navigateur.
Foire aux questions
Is Base64 encryption?
No. Base64 is an encoding format designed for safe binary-to-text transmission, not a cryptographic security algorithm.
