Quick Answer

Frequently Asked Questions

No. The ISO/IEC 18004 specification caps binary capacity at 2,953 bytes, while a typical PDF is hundreds of kilobytes or megabytes. Instead, the QR code encodes an HTTPS URL pointing to where the PDF is hosted. Use a maintained viewing page when the underlying file may be replaced, renamed, or moved after printing.

Google Drive is the most common free option, offering 15 GB of storage. Set general access permissions to 'Anyone with the link' as 'Viewer' so mobile users can open and read the PDF without logging into an account. Show the file type and purpose near the code so users know what will open before they scan.

Use Google Drive's 'Manage versions' feature to upload the new PDF over the existing file, or overwrite the PDF file on your web server with the exact same path and filename. The encoded URL remains identical, so existing codes never break.

The sharing permissions on Google Drive are set to 'Restricted' or limited to an organization domain. Update the file's sharing settings in Drive to 'Anyone with the link' with the role set to 'Viewer'. Use a maintained viewing page when the underlying file may be replaced, renamed, or moved after printing.

For handheld materials like brochures and table tents, print at a minimum of 25 x 25 mm (1.0 x 1.0 inch). For wall posters viewed from 1.5 meters, print at 150 x 150 mm (6.0 x 6.0 inches) while preserving a 4-module quiet zone.
