Scheme, host, port, path, query and fragment — parsed by your browser’s own URL engine rather than a regular expression that is wrong in a dozen perfectly legal cases. Nothing is sent anywhere, which matters for the signed links people paste into tools like this.
Paste anything — it comes apart as you type. Nothing leaves this tab.
Paste into the editor or open a file — everything you add stays in this tab, and you see exactly what the tool will work on before anything runs.
Your browser does all the work locally. Nothing is uploaded — what you paste never leaves this tab, so there’s nothing for anyone to store, scan, or leak.
One press puts it on your clipboard, ready to paste where you need it. There is no file to download — the result is text, not a document. Close the tab and nothing of what you pasted remains.
