What you get

What is the difference between encoding and decoding a URL?

Encoding converts special characters into percent-encoded sequences safe for URLs; decoding reverses that back to readable text.

What happens if I try to decode invalid text?

The tool detects malformed percent-encoding and shows a clear error message instead of crashing.

Does this handle full URLs or just query parameters?

Both. You can encode/decode entire URLs, individual parameters, or any arbitrary text.

Generate and verify Bcrypt hashes with custom salt rounds entirely in your browser.
