Frequently Asked Questions
What can I encode here?
You can percent-encode any text string so it is safe to use in URL query parameters and paths.
Can this help with API debugging?
Yes. It is useful for testing query parameters and encoded payload values.
Is encoded data uploaded anywhere?
No. All encoding happens in-browser.
Example input/output
Input: hello world & more=1
Output: hello%20world%20%26%20more%3D1
How it works
This tool uses JavaScript's encodeURIComponent() to percent-encode special characters in your input so they are safe to use in query strings and URL paths. Processing runs entirely in your browser.
Common use cases
- Encode query parameter values for safe inclusion in URLs
- Prepare text for URL path segments by percent-encoding special characters
- Encode API parameters that contain spaces or special characters
