USING QRCODEBRAIN

QR code questions, answered

Learn how to generate, download and print a QR code, and how static codes, dynamic codes and pricing differ.

How do I generate a QR code?

Enter a full HTTPS URL on the homepage and select “Check URL”. Once generation and file checks finish, download an available format. Tracking parameters, colours and a logo are optional.

Can I change the URL after printing?

A static QR stores the destination URL directly, so changing it requires a new code and replacing the printed copy. A dynamic QR stores a fixed short URL. Sign in to My QR codes to change its destination while keeping the printed code.

Do generation and downloads cost money?

Basic static QR generation and PNG, SVG and PDF downloads are free, with no sign-in required. See Pricing for dynamic-code plans, allowances and renewals, and review the applicable terms before purchasing.

Pricing
Do QR codes expire?

We do not set an expiry date on a static QR code, but its destination website must remain available. A dynamic code also depends on its status, destination availability and the usage rules on Pricing. Neither type is a guarantee of permanent availability.

Pricing
Which files can I download, and why might one be unavailable?

Download PNG, SVG and PDF files that pass their checks. Each format is generated and verified separately; a failed format stays unavailable. Follow the displayed guidance, adjust the URL, style or print settings, then retry.

Can I send the download straight to a large print run?

Print one sample at the intended size and scan it with a phone to confirm the destination. File and print checks cannot replace testing the material, lighting and device. Keep the clear border around the QR code, and avoid stretching or cropping it.

Guide
Can I generate several QR codes at once?

Yes. Open the bulk tool, prepare a CSV using its template, check the rows and download the files that pass. File-size and row limits appear beside the upload control. Edit failed rows and retry.

Do I need tracking parameters?

No. Leave them blank to add nothing. Expand the optional controls when you need to identify a campaign or channel. If the URL already has a matching parameter, choose whether to keep or replace it. These parameters form a URL; they do not guarantee analytics collection or attribution.
