Question 1

How do I encode a URL online for free?

Accepted Answer

Paste your URL, query string, or text into the encoder and the tool instantly applies percent-encoding using JavaScript's encodeURIComponent(). Special characters like spaces and & are converted to their %xx equivalents.

Question 2

What is the difference between URL encoding and HTML encoding?

Accepted Answer

URL encoding (percent encoding) converts characters into %XX sequences for safe transmission in URLs, while HTML encoding converts characters to HTML entities for safe rendering in web pages. They serve different purposes.

Question 3

Which characters are encoded in a URL?

Accepted Answer

encodeURIComponent encodes everything except A–Z, a–z, 0–9, -, _, ., !, ~, *, ', (, ). This includes spaces (%20), &, =, ?, /, :, @, and non-ASCII unicode characters.

Question 4

Can I decode a percent-encoded URL online?

Accepted Answer

Yes. Switch to Decode mode in our URL Encoder tool and paste your percent-encoded string. The tool will use decodeURIComponent() to restore the original characters, all processed locally in your browser.
