A QR code, that little black-and-white square, has become a bridge between the physical world and your online pages. On a poster, a flyer, a business card, packaging: the person scans with their phone and lands exactly where you want. It still has to make people want to scan it, and lead somewhere useful.
Generating it is free and instant. Making it effective is another story. Here are the concrete rules for a QR code that converts, not just a decorative square nobody scans.
Creating your free QR code in seconds
With the Lynks.Pro QR code generator, you paste the destination address (your link-in-bio page, your shop, your menu), and you get your code ready to download. No account required to start, no software to install. Print it or embed it wherever you want.
The golden rule: promise something
A QR code on its own gives no reason to scan it. Nobody pulls out their phone out of pure curiosity. You need a clear promise right next to it: 'Scan for 10% off', 'Scan to see the menu', 'Scan to book'. The promise is what turns an ignored square into an action.
- Bad: a bare QR code, no text. Nobody knows what's behind it.
- Good: 'Scan to download the free guide', with a clear, immediate benefit.
- Excellent: a promise plus a visual that draws the eye to the code.
Placement and size matter
A badly placed QR code is useless. It should be at eye or hand height, big enough to scan without effort (at least two centimeters per side on a close-up display, much bigger on a distant poster), and surrounded by a bit of white space so the camera reads it well.
2 cm minimum
Below two centimeters per side on a close-up display, scanning becomes a hassle and you lose people.
Where the QR code leads: the fatal mistake
The most beautiful QR code in the world is useless if it leads to a slow page, one that's unreadable on mobile, or off-topic. The person made the effort to scan: don't disappoint them. Land them on a mobile-friendly, fast page where the promised action happens immediately. A well-designed link-in-bio page is perfect for this: clear, lightweight, built for the phone.
Measuring to improve
A QR code linked to a URL you control lets you count scans. You know whether your poster is working, which placement performs best, which message triggers the most scans. Without this measurement, you're printing blind. With it, you improve with every campaign.
For shops and restaurants, we wrote a dedicated guide to QR codes in-store, with concrete cases for menus, loyalty cards, and customer reviews.

Frequently asked questions
Does a free QR code expire?
The code itself doesn't expire: it's just an image encoding an address. What can change is the destination. That's why it's better to point it to a link you control, editable at any time without reprinting.
Can I change the destination after printing?
Yes, if your QR code points to a link you control rather than a fixed URL. You change the link's target, and all your already-printed materials automatically lead to the new destination.
How do I know if my QR code is being scanned?
By linking it to a tracked link, you can count scans and watch them over time. You'll know which materials and placements are working, and you stop printing at random.
