FAQ
What URL formats are supported?
Any valid URL including HTTP, HTTPS, FTP, and other protocols. The tool uses the browser's built-in URL parser for maximum compatibility.
Can it parse URLs with authentication?
Yes, URLs with username:password@ format are fully supported and each part is displayed separately.
Is my data private?
All processing happens in your browser. No URLs are ever sent to any server.
How are query parameters handled when the same key appears multiple times?
Repeated keys are preserved as a list rather than overwritten, which matches the behavior of URLSearchParams. This is important because many APIs use repeated keys (e.g., ?tag=foo&tag=bar) to represent arrays.
Does the parser decode percent-encoded characters?
Yes, the displayed values are decoded so you can read them naturally, while the original percent-encoded form is shown alongside for reference. This makes it easy to spot encoding bugs in URLs you receive from APIs or logs.
Can I use this to validate whether a string is a valid URL?
Yes — the tool relies on the WHATWG URL parser, so any input that fails to parse will surface an error. This is the same validation logic used by browsers and Node.js, making it a reliable check for production code.
Why does the origin field sometimes differ from protocol + host?
For most schemes, origin equals protocol + "//" + host, but special schemes (file:, blob:, data:) follow different rules defined by the URL spec. The parser shows you the actual computed origin so you can debug cross-origin behavior accurately.
