Question 1

How does this URL shortener work?

Accepted Answer

Unlike most URL shorteners, this one runs entirely in your browser. It generates a short code from a hash of the original URL — no server call, no signup, no tracking. The short codes are local to your device; if you share a shortened link with someone else, they won't be able to use it without your redirection service. The tool is best for generating memorable short URLs for personal use, QR codes and self-hosting setups.

Question 2

Can I customize the short code?

Accepted Answer

Yes — enter any custom alias of 4-30 characters in the 'Custom alias' field. The alias can contain letters, numbers, hyphens and underscores. Custom aliases let you create memorable, branded short URLs like yourdomain.com/tools or yourdomain.com/sale.

Question 3

Is my data private?

Accepted Answer

Yes, 100% private. No data is sent to any server. All URL shortening happens locally in your browser using JavaScript hashing. Your long URLs never leave your device. For full redirect functionality, you would need to host a redirect service with the generated short codes.

Question 4

How do I generate a QR code for the short URL?

Accepted Answer

Every shortened URL automatically displays a QR code below it. You can right-click the QR code to save it as an image, or click the 'Download QR' button. The QR code encodes the full short URL, so anyone who scans it will see the same destination.
