Question 1

How do I encode or decode a URL with this tool?

Accepted Answer

Pick Encode or Decode mode, paste your URL, query string, or text into the input, and the percent-encoded or decoded result appears instantly. Use the Swap button to push the result back into the input for chained conversions.

Question 2

What does the Swap button do?

Accepted Answer

Swap moves the current output back into the input field so you can immediately run the opposite operation on it. For example, encode some text, then swap and decode it to confirm the round trip matches.

Question 3

When should I use Encode versus Decode mode?

Accepted Answer

Use Encode to turn readable text such as spaces or special characters into percent-encoded form like %20 for safe use in URLs. Use Decode to convert percent-encoded sequences back into the original readable characters.

Question 4

Is the tool free and does it require an account?

Accepted Answer

Yes, it is completely free with no account or sign-up needed. Since all encoding and decoding happens in your browser, it also keeps working even if you go offline after the page has loaded.

Question 5

Is my input text or URL uploaded anywhere?

Accepted Answer

No. Your text, URLs, and query strings are processed entirely in your browser and are never uploaded to a server or tracked, so even sensitive parameters stay on your device.
