URL Encoding Explained

🔗

What is URL Encoding?

URL encoding (percent-encoding) converts characters into a format that can be safely transmitted over the internet by replacing unsafe characters with % followed by hex values.

⚙️

encodeURIComponent vs encodeURI

encodeURIComponent encodes everything including &, =, and ? best for query values. encodeURI keeps those characters as they have meaning in a full URL.

🌍

Unicode Support

Non-ASCII characters like Arabic, Chinese, or emoji are encoded as UTF-8 byte sequences. e.g. "مرحبا" becomes %D9%85%D8%B1%D8%AD%D8%A8%D8%A7

Security Benefits

Proper URL encoding prevents injection attacks by ensuring special characters are treated as data, not as URL structure or code.
