What this tool does
URL encoding converts unsafe or reserved characters into percent-encoded UTF-8 sequences so text can travel safely inside web addresses.
encodeURI keeps full URL separators, encodeURIComponent escapes component separators, form mode uses plus signs for spaces, and strict mode escapes RFC 3986-sensitive characters.
Do not use component encoding blindly on a whole URL unless you intentionally want to encode its slashes, colons, and question marks.
Example
Input: John Doe & Seoul → Output: John%20Doe%20%26%20Seoul
Use cases
- Encoding search query values
- Preparing API parameters
- Cleaning URL path segments
- Encoding form submissions
Tips for better output
- Use component mode for query values.
- Use encodeURI only for complete URLs.
- Use form mode for application/x-www-form-urlencoded data.
- Check decoded preview before publishing links.
