CBOR Encoder / Decoder

CBOR Encoder / Decoder

Encode JSON to CBOR and decode CBOR back to JSON — fully client-side. CBOR (Concise Binary Object Representation) is a compact binary data format defined in RFC 8949, widely used in IoT, WebAuthn, and COSE protocols.

Anwendung

Switch between Decode and Encode modes. To decode, paste CBOR data as hex or base64 and see the JSON output, diagnostic notation, and a detailed byte breakdown. To encode, paste JSON and get CBOR output in hex or base64 format.
