Quel est cet outil ?
Base64 maps binary data to ASCII-safe strings so payloads survive email systems, URL fragments, and legacy transports. Developers decode JWT segments, inspect inline SVG data URIs, or embed tiny blobs in JSON. Calcxzo implements UTF-8 aware helpers because plain btoa mishandles international characters.
Comment utiliser
Place content in the input. Encode converts readable text to Base64; Decode reverses valid Base64 back into UTF-8 text.
Avantages
- Faster than juggling terminal/openssl on shared PCs.
- Educational pairing with JSON Formatter diagnostics.
FAQ
Is Base64 encryption?
No — anyone can reverse it. Treat it as encoding, not secrecy.
