Check the page as a visitor
Copy the published page URL rather than an editing screen, preview session or account dashboard. Open that exact link in a private browser window where you are signed out, then on a phone using mobile data. Check the page, location and next action: a working QR can still lead to a login wall, wrong shop or expired offer. Qex links to your website; it does not publish or back it up.
Choose a fixed URL or an editable destination
Tracking off stores your destination directly in a static QR. It cannot be retargeted after printing, although you can change the page at that same address if you control it. Tracking on creates a Qex short link with an editable destination and scan counts. Dynamic codes depend on Qex continuing to operate, and your website must remain available too. Scan counts are requests, not unique visitors, enquiries or completed purchases.
Update the code that is already printed
Test the new public page first. Open the workspace that owns your existing code, select that code, edit its destination and save. Creating another code gives you a different short link and does not update an old poster. Allow about a minute, then scan the original print and confirm the intended page opens. A changed destination cannot change a printed offer, date or label; replace the print when those words become inaccurate.
Save control before distributing the artwork
A guest workspace depends on its original browser state. Save it with email and open the emailed link to confirm before clearing browser data or handing over the print. Requesting a link alone does not save it. Sign in later with the same saved email to recover the codes on another device. For client work, let the client create and save the workspace in their own browser; sharing the QR image does not transfer editing access.
Make a proof of the final layout
Download SVG for a layout that needs scalable artwork, or PNG for a raster image. Preserve the clear margin around the complete pattern and add a readable website and a label such as “View opening hours”. Test a proof at the final size, on the intended material, before ordering a batch. Standard dynamic codes without a logo use a 21×21 matrix; logos and static URLs can need larger matrices. Matrix size alone does not establish a safe physical print size.
Print guidance and workspace recovery
Use the actual-payload print-size calculator and A4 or US Letter proof to plan your layout, then follow the scan troubleshooting checklist if the final print fails. Test the destination as well as the artwork.
Open the owning workspace to change an existing dynamic code. Save a guest workspace with email and confirm the emailed link, or sign in with the email you saved. Saving a workspace does not make a static QR editable.
How to make and check a website QR code
- Test the public URLOpen the exact visitor link signed out and on a phone. A bare domain is accepted and https:// is added; check that the resulting address works.
- Choose whether the link can changeKeep tracking on for an editable dynamic destination. Turn it off for a fixed URL encoded directly in the artwork.
- Download and save the workspaceExport free PNG or SVG artwork. For a dynamic code, save its owning workspace with email and confirm the emailed link.
- Scan the final printPrint one proof at actual size. Scan it with visitor devices and complete the intended next action before distributing the batch.
Check your QR before printing
Keep the full clear margin around your downloaded QR. Print one proof at the final size, measure it, and scan it with the phones your visitors use before ordering a batch.
Compare QR print dimensions and make an A4 or US Letter proof for a plain, no-logo static link or text code. For your existing dynamic code, paste its Qex short link, rather than the destination, to keep the same redirect in the proof. For a code with a logo, frame, Wi-Fi details or a contact card, test the actual downloaded artwork; the plain calculator does not reproduce that design.
Diagnose a QR code that will not scan or open if a proof fails.
Questions
Why does my QR open a login page?
Test the saved destination directly in a signed-out browser. If it asks for login there too, check your website publishing or access settings and use the public visitor URL. A larger QR will not remove a login wall.
Can I put my own domain inside the QR?
With tracking off, a static QR contains your website URL directly. With tracking on, the printed QR contains a qex.me short link and redirects to your chosen destination. This generator does not configure a custom redirect domain.
Can I change the website after printing?
Edit the existing dynamic code in its owning workspace. A new code will not update the old print. A static QR keeps its encoded URL, so keep that address working or replace the artwork.
What happens if I pause the code?
Visitors see a paused page instead of your website. Unpause the same code to resume; its printed pattern stays the same.
How do I edit my code from another device?
First save the guest workspace with email and confirm its emailed link. Then sign in on the other device with that same email. Keep the original browser state until confirmation; possession of the QR image does not grant editing access.
Does a logo keep the code at 21×21?
No. The 21×21 figure applies to standard dynamic codes without a logo. Logos and static URL payloads can need larger matrices. Test the actual exported artwork and final print rather than choosing a size from that figure alone.
