Override only when Auto cannot parse your paste. Changing this loads a matching sample into Input — click Convert to run. Use Load sample to cycle every format example.

All conversions

Read-only representations of the same 16 bytes. Every textual form is listed here, not in “Prefer format”.

Paste two values: if both sides are valid JSON, a structural diff appears; otherwise UUID / bytes are compared when both decode to the same format.

A
B

Create or edit JSON here (syntax colors), then format, validate, or convert - same as MongoDB $binary UUID blobs on the Convert tab once detected.

New document

Hash, HMAC, AES-GCM/CBC + RSA-OAEP, codecs, JWT decoding, UUID v4, and secure random - all client-side. JWTs use Base64URL (three segments), not a single MIME Base64 block - use Decode JWT below, not raw Base64 decode.

About Password Generator

A memorable password is, almost by definition, a guessable one. For anything a password manager will remember for you, a long random string beats a clever pattern every time.

Set a length and choose which character sets to include - lowercase, uppercase, digits, and symbols - then generate a password sourced from crypto.getRandomValues, the same cryptographically secure randomness source used elsewhere on this site for UUIDs and tokens, not Math.random().

Nothing generated here is sent anywhere or stored - copy it straight into your password manager.

FAQ

How long should a generated password be?
16 characters or more is a reasonable default for most accounts when using a full character set; go longer for anything high-value, and prefer a passphrase-style manager-generated password where the service allows it.
