About URL Decoder
Decode percent-encoded URL strings back to human-readable text. Paste a URL-encoded string and the tool instantly converts %20 back to spaces, %26 back to &, and all other percent-encoded sequences to their original characters. Useful for debugging URL query parameters, reading encoded API request logs, understanding redirects, and inspecting tracking parameters. Handles both standard percent-encoding and + as a space (form encoding). Real-time decoding shows results as you type. All processing is client-side –no data is sent to a server.
Frequently Asked Questions
What does %20 mean?
%20 is the percent-encoded representation of a space character (ASCII code 32 = hex 0x20).
Why does + sometimes mean a space?
In application/x-www-form-urlencoded format, + represents a space. The tool handles both + and %20 as space characters.
Can I decode a full URL with query parameters?
Yes. Paste the entire URL and the tool decodes all percent-encoded sections while preserving the URL structure.
