Encode and decode URL strings using percent-encoding (also known as URL encoding). This tool handles spaces, special characters, Unicode, and query string parameters instantly in your browser — no server required.

- Encode any text or URL to percent-encoded format (
%20,%3A, etc.) - Decode a percent-encoded URL back to readable text
- Handle full URLs or individual query parameter values
- Encode Unicode characters (e.g. Chinese, Arabic, emoji) to safe ASCII
- Supports both

FAQ
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL and preserves characters like /, ?, #, and &. encodeURIComponent encodes a single parameter value and converts those characters too. Use encodeURIComponent for query parameter values.
Why does a space become %20 and not +?
Both %20 and + represent spaces in URLs, but in different contexts. %20 is the RFC 3986 standard. + is specific to application/x-www-form-urlencoded format used in HTML form submissions.
