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 Hex Converter

Sometimes you need to see the actual bytes behind a string - debugging an encoding mismatch, reading a hex dump from a log, or reverse-engineering a binary protocol.

Convert UTF-8 text to hex or hex back to text instantly. The decoder expects continuous hex pairs, so strip spaces or colons from copied hex dumps before pasting.

FAQ

Spaces in hex?
Decoder accepts continuous hex pairs; remove separators before decoding.
