Question 1

What is a URL Shortener and why should I use it?

Accepted Answer

A URL shortener transforms long, clunky URLs with complex UTM tracking parameters into short, elegant links (e.g. ndllink.vercel.app/sale). It makes your links cleaner for social sharing, print materials, SMS campaigns, and provides in-depth click analytics.

Question 2

Are short links permanent and 100% free?

Accepted Answer

Yes! ShortLink provides free, permanent link shortening with unlimited redirects. You can optionally configure an expiration date or click limit quota if you are running a limited-time marketing promotion.

Question 3

How do dynamic QR codes work with short links?

Accepted Answer

Every short link you generate automatically creates a dynamic QR code. Because the QR code encodes your short link rather than the raw destination, you can update your destination URL anytime from your dashboard without having to re-print your promotional brochures, menus, or packaging.

Question 4

Can I protect sensitive links with a password?

Accepted Answer

Yes. You can enable password protection on any link during creation or anytime later. Visitors will be greeted with a modern passcode screen before being redirected to the final destination.

Question 5

How does ShortLink protect against malware and phishing?

Accepted Answer

We implement strict Server-Side Request Forgery (SSRF) validation, automatically block private IP addresses (127.0.0.1, 10.x, 192.168.x), filter dangerous schemes (javascript:, data:), and maintain a community abuse reporting system to promptly review flagged links.
