URL Encoder / Decoder

Does this URL Encoder / Decoder tool send my data to any server?

No. All encoding, decoding, parameter cleanup, inspection, and short URL simulation happens entirely in your browser. Nothing is uploaded or stored on any server.

What can I do with the Encode / Decode tab?

You can encode or decode URLs and arbitrary text using percent-encoding, URI/URL methods, or form-style encoding. The tool also supports options like preserving Unicode characters and treating spaces as + for form data.

What is the difference between encoding modes like percent, component, and form?

Percent mode uses standard percent-encoding, component mode behaves like encodeURIComponent / decodeURIComponent, and form mode follows HTML form-style encoding where spaces may be encoded as +.

What does the URL Parameters tab do?

It extracts query parameters from a URL or raw query string, optionally removes tracking parameters, drops empty values, collapses duplicates, normalizes keys, and then rebuilds a cleaned URL and JSON view of the parameters.

How does the Inspector / Validator tab help?

The inspector parses a URL into protocol, hostname, port, path, hash, origin, and query string. It shows validation errors and warnings, and can normalize the URL by forcing HTTPS, removing default ports, cleaning slashes, and canonicalizing query parameters.

Is the short URL generated in the Shortener Simulator real?

No. The Shortener Simulator never calls real shortening services. It generates a fake, random-looking short path under a domain you choose, so you can safely test redirect flows and UI behavior without exposing real data.

Can I copy or download the results from each tab?

Yes. You can copy outputs (encoded/decoded text, cleaned URLs, normalized URLs, and simulated short URLs) to the clipboard, and in many cases download them as text or JSON files directly from the tool.

What happens if my input is invalid or cannot be decoded?

If encoding or decoding fails, or the URL cannot be parsed, the tool shows a clear error message at the top and avoids producing partial or misleading output.
