Question 1

What is URL encoding?

Accepted Answer

URL encoding (also called percent encoding) converts special characters into a format that can be transmitted over the internet. Spaces become %20, and special characters are replaced with %HH where HH is the hexadecimal value of the character.

Question 2

Why do URLs need encoding?

Accepted Answer

URLs can only contain certain characters safely. Special characters, spaces, and non-ASCII characters must be encoded to ensure the URL is properly transmitted and interpreted by servers and browsers.

Question 3

What characters get encoded?

Accepted Answer

Reserved characters (like : / ? # [ ] @ ! $ & ' ( ) * + , ; =), spaces, and non-ASCII characters are encoded. Safe characters like letters, digits, hyphens, underscores, periods, and tildes typically don't need encoding.

Question 4

What's the difference between encoding and decoding?

Accepted Answer

Encoding converts readable text with special characters into URL-safe percent-encoded format. Decoding reverses this process, converting percent-encoded characters back into readable text.

Question 5

Can I encode an entire URL?

Accepted Answer

Yes, you can encode individual parts of URLs. However, encoding the entire URL including colons and slashes will break its structure. Typically, you encode query parameter values and path segments separately.

Question 6

Is this operation secure?

Accepted Answer

URL encoding is performed entirely in your browser. No data is transmitted to any server. Your text never leaves your computer, ensuring complete privacy for sensitive information.
