How to use this tool

Limits and behavior
Nested objects and nested arrays are rejected. Null becomes an empty value. Encoding follows URLSearchParams rules, including plus signs for spaces. Input is limited to 1 MB and output to 3 MB. No input content is saved by CraftAI.
Create URL query parameters
Convert supported JSON fields into encoded query components for web requests.
Does query-string encoding encrypt the values?
No. URL parameters are visible in browser history, logs and links. Avoid putting secrets in query strings.
