1. Always Use Vector

Embed the code as a vector path inside the PDF, not a raster image. Most PDF generation libraries accept SVG directly. A vector code prints sharply at any size without pixelation.

2. Verifying the Link

Before distributing a PDF, scan the embedded code on a real device. PDF viewers sometimes rasterize embedded images at low resolution during preview.

3. Quiet Zone

PDF layout tools can shrink graphics to fit a box. Check that the quiet zone is preserved after layout; add extra padding inside the graphic if needed.

4. Accessibility

Add alt text to the QR code image element and include the URL as visible text or a hyperlink nearby. Screen readers cannot scan QR images.
