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

The worst QR code mistake appears after a layout is published or a print run is finished. The code may point to an old page, disappear into the background, or fail at the chosen size. A useful check starts with the final URL and ends with the code inside the finished design.

Prepare the final destination

Open the URL manually on a phone and confirm that the page works without an internal network or login. Follow any redirects to the final page. Printed material needs a stable address that will remain available after the design is distributed.

Generate the code and choose a file format

Paste the link into the generator and begin with a dark code on a light background. PNG works well in documents, presentations, and web posts. SVG is better for print because it can scale without blurring the module edges.

• Do not crop the clear margin around the code.
• Do not place the code over a photo or busy texture.
• Avoid foreground and background colors with similar brightness.
• Do not enlarge a raster PNG beyond its original resolution.

Test the code in the final layout

A code that worked in the generator may fail after resizing, cropping, or decoration. Export the finished layout and test that file. For print, create a sample at the real physical size instead of scanning an enlarged version on a monitor.

Scan with two different devices

Scan from the expected distance with at least two phones. Check the address preview before opening the page. Test a poster from normal viewing distance and test packaging under ordinary light, including any curve in the surface.
