What is URL Encoding and Decoding?

URL Encoding (Percent-Encoding)

URL encoding, also known as percent-encoding, replaces special characters in a URL with a % (percent sign) followed by a hexadecimal value. This ensures that URLs remain safe for transmission across the web.

Example:
Original URL: https://www.example.com/page?name=John Doe&age=30
Encoded URL: https://www.example.com/page?name=John%20Doe&age=30

URL Decoding

URL decoding reverses this process, converting encoded characters back to their original format.

Example:
Encoded URL: https://www.example.com/search?q=best%20SEO%20tools
Decoded URL: https://www.example.com/search?q=best SEO tools

This is essential for recovering original URLs, analyzing web traffic sources, and debugging URL parameters.

Why Do You Need URL Encoding?

1. Secure URL Transmission

URLs often contain special characters like spaces, ampersands (&), and equal signs (=), which can cause errors in web browsers, search engines, and APIs. Encoding ensures that URLs function correctly in all environments.

2. Improve SEO & Web Performance

Search engines prefer clean, properly formatted URLs. Encoding removes unwanted characters that could interfere with indexing.

Example of a bad URL:

Example of an optimized URL:
https://www.example.com/search?query=best%20tools%20SEO%20tips

3. Handle URL Parameters Efficiently

Many websites use query strings (?name=value&name2=value2) for tracking, session IDs, and data transmission. Encoding ensures that these parameters remain intact and functional.

4. Prevent URL Injection & Security Risks

Encoding special characters prevents malicious script injection and ensures that URLs are safe to share and store in databases.

5. Decode URLs for Better Analysis

Digital marketers and webmasters often receive encoded URLs in tracking reports. Decoding them helps analyze campaign performance, source tracking, and user behavior.
