Common questions
Is encoding encryption?
No. Anyone can decode an encoded value. Never treat it as protection for secrets.
Why does a plus sign remain a plus?
This tool follows encodeURIComponent/decodeURIComponent, not HTML form rules. A literal + is not decoded as a space. Malformed percent escapes show an error.
