Free QR Code Generator

A QR (quick response) code is a type of 2D barcode, made up of a 2-tone pixel pattern. Unlike a traditional barcode, a QR code is able to contain more information and is scannable from any orientation. They were first used by Denso Wave, who developed them for marketing components, but soon found their way into mobile marketing when smartphones were more widely adopted. 

QR codes work by translating the arrangement of a provided URL into a unique 2D arrangement of squares. When these squares are scanned, the optical scanner rearranges them back into the URL’s original form so you can access the link.

Yes! Canva’s QR code generator is totally free and easy to add to any design, from shirts to flyers and business cards. If you’re a Free, Pro, Canva Education, or Canva for Nonprofit user, the QR codes you generate have a Canva logo by default.

If you have Canva Business and Canva Enterprise, you can remove the default Canva logo and add your own logo to the QR code.You also get access to preset logos, including Facebook, YouTube, Instagram, TikTok, WhatsApp, X, and LinkedIn, depending on your location.

Only the person who created the dynamic QR code can edit its link and settings across any design. If you created the QR code, you can change the link at any time.

To update or replace your QR code’s link, select the QR code in your design, then click Edit from the toolbar. Update the link in the URL field, then click Save. Note that changing the destination URL updates the QR code across all designs where it appears.

The simple answer is no, your QR code won’t expire. Our QR code generator allows you to create static and dynamic QR codes that are valid forever. If you want to update or replace your QR code’s link, select the QR code in your design, then click Edit from the toolbar. Update the link in the URL field, then click Save.

However, your QR code may get deactivated if the linked content doesn't meet Canva's platform guidelines. Update the link with appropriate content and save. Your QR code will be reviewed and reactivated if everything looks good.

Static QR codes are fixed when they’re created. This means the link attached can’t be updated if it breaks, so you’ll have to generate a new QR code if that happens. On the other hand, dynamic codes are editable and can be changed.

Canva’s QR code generator gives you the option to generate either static or dynamic QR codes. If you create a dynamic QR code, you can update the destination URL without changing the design of the QR code and reprinting all your materials. If your QR code is used across multiple designs, updating the URL will update it across all designs at once.

Meanwhile, if you create a static QR code, the destination URL is locked in; it’s a reliable and permanent option for web addresses that never change, like your social media and contact pages.

No. QR codes from the static QR code app can't become dynamic. Create a new dynamic QR code in your design to update links or see scan details.
