Paste any base64 payload — command-line arguments, embedded certificates, encoded scan parameters. Instant, readable breakdown, entirely in your browser. Zero sign-up, completely free.
Nothing you paste here leaves your browser — decoding and parsing happen entirely client-side.
From encoded mystery to readable evidence in seconds
Drop in any base64 string — a command-line argument, a scan payload, or an embedded certificate.
Auto-detect figures out whether it's text/JSON or a DER-encoded X.509 certificate, and parses accordingly.
Get a clean breakdown — Issuer, Subject, validity dates, SANs, or formatted JSON. No install, nothing stored.
