Question 1

What is URL encoding?

Accepted Answer

URL encoding (also called percent-encoding) converts special characters like spaces, &, ?, = into safe ASCII codes (e.g. space becomes %20) so they can be safely transmitted in URLs.

Question 2

When do I need to URL encode?

Accepted Answer

When building query strings, passing parameters in URLs, or handling form submissions that contain special characters, spaces, or non-ASCII characters.

Question 3

What is the difference between encode and decode?

Accepted Answer

Encoding converts plain text to percent-encoded format. Decoding reverses this — converting %20 back to a space, %26 back to &, etc.

Question 4

Does this tool handle Unicode characters?

Accepted Answer

Yes. Non-ASCII characters like Arabic, Chinese, or emoji are first converted to UTF-8 bytes, then each byte is percent-encoded.
