cURL is the universal way to share API examples in documentation, but browser JavaScript uses the fetch() API. Converting cURL commands lets you test APIs directly in your browser code, React/Vue components, or Node.js without installing curl. This tool handles all flags: -H headers, -d body, -X method, --data-urlencode, and --compressed.
Each -H 'Header: Value' flag becomes an entry in the fetch headers object. Authorization headers, Content-Type, Accept, and custom headers are all mapped. The tool preserves exact header names and values including multi-value headers.
Yes. A cURL -d '{"key":"value"}' or --data-raw flag is placed in the fetch body property as a string. If the Content-Type is application/json, the output wraps the body in JSON.stringify() so you can pass an object directly rather than a raw string.
Client certificate flags (-E, --cert), proxy settings (--proxy), and low-level socket options don't map to fetch(). File upload with @filename is converted to a FormData placeholder you fill in manually. Basic auth (-u user:pass) is converted to an Authorization: Basic header with the base64-encoded credentials.

This tool parses common curl options and maps them to browser-friendly fetch(). It handles headers, method, JSON bodies, form data, and cookies. Some curl-only runtime flags are intentionally surfaced as warnings so your generated code stays explicit and production-safe.
For payload and URL debugging, pair this with JSON Formatter, JSON Validator, URL Parser, Query String Parser, and URL Encoder/Decoder.
For auth and request-debug workflows, also try JWT Decoder, Base64 Encoder/Decoder, Hash Generator, String Escaper, and JSON Schema Generator.
