URL encoder, decoder and query inspector
Convert URL components or explain a complete URL locally. This tool never opens or requests the address.
Up to 64 KB. URL inspection requires an absolute address with a scheme.
Result
Encoding and inspection
Component mode uses percent encoding for one URL component. Inspection separates an absolute URL into protocol, host, path and decoded query parameters.
A parser, not a safety verdict
The tool does not open the address, follow redirects, check reputation or prove a link is safe. Review unexpected protocols and destinations yourself.
Local and request-free
Processing begins only after you click a button. The input is not placed in the page URL, storage, analytics or a network request.
Frequently asked questions
Does this tool send my input to a server?
No. The tool runs in this browser after you choose to use it. Your pasted content or generated result is not added to URLs, storage, analytics or server requests.
Does a clean result guarantee that an email or account is safe?
No. These tools explain technical clues and reduce routine risk, but they cannot replace your judgment, malware protection, account security controls or advice from a qualified security professional.
