How to use this text tool

Paste the text or URL component.
Choose whether you are encoding a full URI, component, form value, or RFC 3986 value.
Review the decoded meaning and length.
Copy the encoded output.

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.

Processing details

encodeURI keeps full URL separators, encodeURIComponent escapes component separators, form mode uses plus signs for spaces, and strict mode escapes RFC 3986-sensitive characters.
