FAQ
When do I need URL encoding?
When a URL contains Chinese characters, spaces, or special symbols (&, =, ?, etc.), encoding prevents incorrect parsing by browsers or servers.
Does encoding make the URL longer?
Yes, special characters are replaced with percent-hex representations. For example, spaces become %20 and multi-byte characters become longer encoded sequences.
Can I encode only query parameters?
Yes, the tool supports pasting full URLs or just query parameter strings, letting you choose the encoding scope as needed.
