Is generating a QR code from a URL free?

Yes. URLNIX generates a QR code for every short link at no cost. Downloading it as a high-resolution PNG is available to all registered users, including free accounts.

Does the QR code change if I edit the destination URL?

No. The QR code encodes the short link (`urlnix.live/code`), not the destination URL. If you edit where the link points, the QR code stays the same and automatically redirects to the new destination.

Can I customise the colors of the QR code?

Not currently in URLNIX — QR codes are generated in standard black-and-white high-contrast format for maximum scan reliability.

Do I need a separate app to generate QR codes?

No. QR codes are generated automatically for every shortened link in your URLNIX dashboard, with no additional tools required.

Can I use the QR code on a commercial product?

Yes, there are no restrictions on commercial use of QR codes generated via URLNIX.

How to Generate a QR Code from a URL (Free & Instant)

Every link you shorten on URLNIX automatically gets a scannable QR code. You can view it, download it as a high-resolution PNG, and track QR scans separately from direct link clicks — all without installing an app or signing up for a separate QR service.

How to Get a QR Code for Your Link

Shorten your URL at urlnix.live — no sign-in required for a basic guest link
Once the short link is created, click on it to open the link detail panel
Find the QR Code section in the detail panel
The QR code is displayed immediately — you can scan it right away to test it

To download the QR code as a PNG file, click the Download QR Code button. High-resolution downloads are available to all registered users (free and Pro).

What Resolution Is the QR Code?

URLNIX generates QR codes at high resolution — suitable for both screen display and print. The downloaded PNG is large enough to print clearly on:

Business cards
Flyers and posters
Product packaging
Event signage
Restaurant menus

Can I Use My Own Domain in the QR Code?

If you're a Pro user with a verified custom domain configured (e.g., go.yourbrand.com), links created under that domain will generate QR codes that point to your branded short URL rather than urlnix.live. This keeps your brand consistent across both digital and print channels.

How to Track QR Code Scans Separately from Link Clicks

URLNIX automatically distinguishes QR code scans from direct link clicks in your analytics. When a visitor scans the QR code, the click is tagged with source=qr. In your analytics dashboard you can see:

Total QR scans vs. direct link clicks
Which countries scanned your QR code
What devices were used to scan (overwhelmingly mobile)

This is useful for measuring the effectiveness of printed materials — for example, to know whether people are actually scanning the QR code on your flyer.

Best Practices for QR Codes That Actually Scan

Contrast matters most. Dark modules on a light background. Never reverse this — light on dark reliably fails on some scanners.

Don't crop the quiet zone. The white border around the QR pattern is called the "quiet zone." Scanners use it to isolate the code. Cropping it too tight causes scan failures.

Minimum print size. For close-range scanning (tables, menus), print at least 2 cm × 2 cm. For posters meant to be scanned from 1–2 metres, increase to at least 6 cm × 6 cm.

Test before printing. Always scan the QR code from the actual printed output on multiple different phone models before running a print campaign.

Use a redirect, not a long URL directly. QR codes encoding long URLs have more dense patterns that are harder to scan reliably. A short URL like urlnix.live/abc123 produces a simpler, more scannable QR code.

Do QR Codes Expire?

On URLNIX:

Guest links (no sign-in) expire after 24 hours — the QR code stops working at the same time
Free account links are permanent — the QR code never expires as long as the link is active
Pro users can optionally set an expiry date or click limit on any link, after which both the link and its QR code deactivate
