Runs entirely in the browser; nothing entered into the tool is uploaded.

> A URL Parser splits any URL into its component parts — protocol, host, port, path, query parameters, and hash — and shows each parameter as an editable row, all using the browser's native URL constructor with zero network activity.

Paste a URL — including the noisy tracking variants with a dozen utm_ parameters — and instantly see its structure. Each query parameter is decoded and shown in a table so you can read it. Edit a value or toggle a parameter off and the rebuilt URL updates live. Built on the standard `new URL()` and URLSearchParams Web APIs.

## Features

- Splits any URL into protocol, host, port, path, query, and hash
- Renders every query parameter as an editable, toggleable row
- Live-rebuilds the canonical URL as you edit
- One-click strip of UTM and other tracking parameters
- Built on the native URL and URLSearchParams APIs

## Use cases

- Cleaning a UTM-stuffed marketing URL before sharing it
- Auditing the parameters a third-party tracker is sending
- Editing one parameter inside a long URL without retyping the whole thing
- Verifying that an OAuth callback URL encodes everything it should

## How to use it

1. **Paste your URL** — Paste any URL into the input field.
2. **Inspect the parts** — Every section (protocol, host, path, params, hash) is shown individually with copy buttons.
3. **Edit and rebuild** — Toggle off unwanted parameters or edit any value — the rebuilt URL updates live.

## When to use it, and when to use something else

- **vs `new URL()` in the browser console** — use URL Parser when you want every parameter as a visible editable row. Use `new URL()` in the browser console when you are already scripting.
- **vs Shortlink services** — use URL Parser when you only need to read the URL, not republish it. Use Shortlink services when you need a shorter shareable form.

## Frequently asked questions

### What does the parser show me?

Protocol, username/password (if present), hostname, port, pathname, every query parameter as a key/value row, and the URL fragment (hash). Each piece is individually copyable.

### Why are some characters in my URL different after parsing?

The native URL constructor normalises encoding. For example, spaces appear decoded in the parameter table but re-encoded as %20 in the rebuilt URL — which is correct per the URL spec.

### Can I edit parameters and rebuild the URL?

Yes. Toggle off or change any parameter and the canonical URL updates immediately. Useful for cleaning tracking parameters before sharing a link.
