FAQ
Short answers before you paste real data.
What is percent encoding?
Percent encoding represents reserved URL characters with a percent sign and hexadecimal code so they can travel safely in URLs.
Can malformed encoding be decoded?
No. If the input contains broken percent sequences, the tool shows a clear error instead of guessing.
Does parsing a URL contact that URL?
No. Parsing is local string processing and does not request the page.
