Privacy: why it matters for curl conversion

curl commands are often copied directly from API docs, terminal history, or Postman — and they frequently contain live credentials: Authorization: Bearer sk-..., database passwords in URLs, HMAC signatures, or session cookies.

voiddo curlfetch never makes a network request after the page loads. Your command is parsed in a JavaScript tokenizer running locally. curlconverter.com parses server-side, which means your command travels over HTTPS to their infrastructure. For non-sensitive commands, that's fine. For commands with real credentials, local parsing is strictly safer.

Frequently asked questions

Is voiddo curlfetch an alternative to curlconverter.com?
Yes, for JavaScript fetch() output. voiddo curlfetch parses your curl command entirely in the browser — your API keys, auth tokens, and request bodies stay on your machine. curlconverter.com is better when you need output in Python, Go, or other languages, and when your command contains no sensitive data.
Does voiddo curlfetch send my curl command to a server?
No. curlfetch parses everything in JavaScript running in your browser tab. After the page loads, no network requests are made. Nothing you type is transmitted — not your URLs, not your headers, not your API keys.
Which flags does curlfetch handle that curlconverter.com doesn't?
curlfetch converts --max-time and --connect-timeout into an AbortController with the appropriate timeout, which curlconverter.com does not currently include in its JavaScript fetch() output. Both tools handle the common flags: -X, -H, -d, -u, -b, -L, -k.
Does curlfetch support multipart form uploads (-F)?
Not currently. If your curl command uses -F or --form for multipart uploads, curlconverter.com is the better choice — it produces the FormData append calls needed for multipart requests in JavaScript.
Is voiddo curlfetch free?
Yes, completely free with no ads, no signup, no rate limits. It is part of the 63+ free developer tools at tools.voiddo.com.
