Frequently Asked Questions

A URL shortener is a service that takes a long web address (URL) and converts it into a shorter, more manageable link. These short links are easier to share, remember, and often allow for click tracking. This page provides a client-side *demonstration* of how such a tool might look and feel, but it does not create publicly usable short links.

When you paste a long URL and click "Shorten," JavaScript generates a representative "short link" and a QR code. This information, along with the original URL, is stored locally in your browser's `localStorage`. When you use a "short link" created on this page, JavaScript will redirect you to the original long URL.

Partially. The "short links" (e.g., `nftbtc.us/xxxx`) work in two ways:

  1. When used directly within this website (by clicking the short URL in the "My Links" section), they will correctly redirect to the original long URL.
  2. If you paste a short link directly into your browser (e.g., nftbtc.us/your-alias), it will work only if you've previously created that link on the same device and browser. This is because all links are stored locally in your browser's storage.

These links are not registered on a central server database, so they won't work if shared with someone else or used on a different device. A true, publicly shareable URL shortener requires a backend server and database.

This demo includes several advanced features that simulate what real URL shorteners offer:

  • Password Protection: You can add a password to your link, which is stored locally. When the link is accessed, users will need to enter the password.
  • Expiration Dates: Links can be set to "expire" after a certain date, after which they will no longer redirect.
  • Click Tracking: The demo tracks how many times a link has been clicked, but only within your browser.

All of these features are simulated client-side using your browser's localStorage, so they only work on your current device.

localStorage is a web storage feature that allows websites to store data (key-value pairs) in a user's web browser with no expiration date. This data persists even after the browser window is closed and reopened. In this demo, we use it to save the links you create so you can see them in the "My Links" section.
