Click Convert when ready

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.

Examples

  • POST JSON body 
    {"hello":"world"}

About Online cURL Client

Testing an API endpoint shouldn't require opening a full desktop client just to fire off a GET request and see the response.

Send GET, POST, PUT, PATCH, and DELETE requests straight from your browser via fetch - view status, headers, and body, then copy the whole thing as a ready-to-run curl command for your terminal or CI script.

Requests run directly from your browser tab, not through our servers, so cross-origin APIs still need to allow CORS. If a request is blocked, use Copy as curl and replay it from a terminal instead.

FAQ

Why CORS errors?
Browsers block cross-origin responses unless the API sends Access-Control-Allow-Origin.
