Question 1

What is URL encoding?

Accepted Answer

URL encoding (percent-encoding) converts special characters into a format that can be safely transmitted in a URL. For example, spaces become %20 and & becomes %26.

Question 2

What is the difference between full URL and component encoding?

Accepted Answer

Full URL encoding preserves URL structure characters like /, ?, and &. Component encoding encodes everything including those characters — use it for individual query parameter values.

Question 3

Is my data sent to a server?

Accepted Answer

No. All encoding and decoding happens in your browser using JavaScript. Your data stays private.

Question 4

When should I use URL encoding?

Accepted Answer

Use it when building URLs with special characters in query parameters, or when you receive a percent-encoded URL and need to read it.

Question 5

What characters get encoded?

Accepted Answer

Characters outside the unreserved set (A-Z, a-z, 0-9, -, _, ., ~) get percent-encoded. In component mode, reserved characters like /, ?, and & are also encoded.
