JWT Decoder vs Unix Timestamp Converter

JWT Decoder
Decode and verify JSON Web Tokens — header, payload, claims, and signature.
Paste a JSON Web Token to instantly decode its header and payload. Optionally supply a secret or public key to verify the signature.
Example input:
{
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c"
}datetime
Unix Timestamp Converter
Convert Unix timestamps to human-readable dates and ISO 8601, or convert dates back to epoch seconds.
Convert Unix epoch timestamps (seconds or milliseconds since 1970-01-01T00:00:00Z) to ISO 8601, UTC, and local date-time strings — or parse any date string back to a Unix timestamp. Shows the relative time from now (e.g. '3 days ago'). Accepts seconds, milliseconds, or an ISO 8601 / RFC 2822 date string as input.
Example input:
{
"input": "1716998400",
"mode": "to-date"
