How to create a QR code for a link and test it

Use the final destination URL

Paste the exact link visitors should open. Prefer a complete HTTPS URL instead of a short internal note or unfinished draft link.

If the link has tracking parameters, test that the final page still loads correctly on mobile.

Choose a size and error correction level

Larger QR codes are easier to scan from a distance. Higher error correction can help when a code is printed, handled, or placed in a busy design.

Shorter URLs usually create simpler QR patterns, which can scan more easily than very long text.

Download a scalable format

SVG is useful for documents, signs, and print drafts because it can be scaled without becoming blurry.

If another app needs PNG or JPG, export from a design tool after placing the SVG.

Scan-test before publishing

Test the QR code with more than one phone camera if the code will be printed or used at an event.

Check the scan distance, lighting, contrast, and whether the landing page is mobile-friendly.

Make the destination clear first

A QR code is only useful if the link behind it is correct, mobile-friendly, and trusted. Open the final link on a phone before generating the code. If the page is slow, redirects too many times, requires login unexpectedly, or is not ready for mobile visitors, fix the destination before printing or sharing the QR code.

QR code publishing checklist

Test more than once

Scan the QR code with at least two phones if it will be printed for customers, students, event guests, or product packaging. Test under the same conditions where people will scan it: indoor lighting, distance from a poster, glossy paper, or a phone screen.

When to regenerate the code

Regenerate the QR code if the destination URL changes, if you add tracking parameters, if the printed version is too small, or if the contrast is weak. If the link is already printed on flyers, use a stable redirect URL that you control so the destination can be updated without reprinting every asset.

Good QR code destinations

The best QR destinations are stable pages that load quickly on mobile: menus, signup forms, event pages, product pages, download pages, Wi-Fi instructions, classroom resources, or support forms. If the destination requires login, make that clear near the code so visitors are not surprised after scanning.

Tracking and privacy

Campaign tracking parameters can help measure scans, but do not make links unnecessarily long or confusing. Decode tracking URLs before publishing so you understand what information is included. If the QR code appears in a public place, assume anyone can scan it and view the destination.

Print proofing

Before printing many copies, test one copy at the final physical size. Scan it from the expected distance, under realistic lighting, and at a slight angle. If scanning fails, increase size, improve contrast, or simplify the destination URL.

For public signs, add a short human-readable URL near the code as a backup. That gives visitors another option if their camera app fails, the code is damaged, or lighting makes scanning difficult.

Where QR codes work best

QR codes are strongest when they remove typing from a real-world workflow. Good examples include restaurant menus, classroom resources, event check-in pages, product manuals, feedback forms, appointment pages, digital coupons, and landing pages for printed flyers. They are less useful when the link is already easy to click, such as inside an email or website button.

Accessibility and fallback links

When possible, place a short readable URL near the QR code. This helps visitors who cannot scan, people using older devices, and anyone viewing a damaged printout. Also add a short label such as “Scan for menu” or “Scan to register” so people know what will happen before opening the camera.

For public or customer-facing materials, avoid pointing a QR code directly to a file download unless the visitor clearly expects it. A normal landing page with context, privacy information, and a visible call to action is usually safer and more trustworthy.
