WebRTC SDP Inspector

Parse an SDP offer, answer, or both locally. This page never creates a peer connection or sends candidates.

Limits per document: 512 KiB, 5,000 lines, 4,096 characters per line, 64 media sections, 2,000 candidates. Strictly requires SDP x= line grammar. Inspection is structural—not ICE connectivity, DTLS identity, codec implementation, or cryptographic verification.
