Questions
Why are there still % signs after decoding?
The text was encoded twice, so each % became %25: %2520 decodes to %20, and decoding that again gives a space. Paste the result back in to remove another layer.
How do I read a long query string?
Paste the whole URL, or just the part after the ?. Each parameter appears below on its own line, decoded, in order, with repeated keys kept and + read as a space, as browsers read them.
Why does Whole URL leave some escapes alone?
Decoding %2F to / or %26 to & in a full address would change where it points or how its query splits. Whole URL keeps those as they are (a%2Fb%20c gives a%2Fb c); Component decodes everything.
What does an invalid escape mean?
Every % needs two hex digits after it, and the bytes must be valid UTF-8. caf%E9, é in the older Latin-1 encoding, gives “Invalid escape "%E9" at position 4: not valid UTF-8”.
Is my URL sent anywhere?
No. Decoding and reading a URL’s parts happen in this tab, and the URL is never opened or fetched. It isn’t sent to our servers or kept after you leave the page.
