Understanding URL Decoding

Reading Query Strings

Reveal the human-readable value behind a percent-encoded query string parameter pulled from server logs or browser URLs.

Debugging Requests

Quickly inspect what data an API request actually sent without writing a script.

Internationalized Text

Decode UTF-8 percent-encoded sequences back into accented characters, emoji, or non-Latin scripts.

Security Review

Inspect obfuscated or encoded payloads in URLs as part of a security or log-analysis workflow.

How URL Decoding Works

This tool uses JavaScript's decodeURIComponent to reverse percent-encoding: each %XX sequence is converted back to its original byte, and UTF-8 byte sequences are reassembled into the correct Unicode characters.

Key Takeaways

Reverses encodeURIComponent: Decodes values encoded for use inside a single URL component or query parameter.
Handles '+' as Space: Also converts the common form-encoding '+' character into a literal space before decoding.
Client-Side Only: All decoding happens locally in your browser — no data is ever sent to a server.
