A QR code for a document: where to keep the file
Cloud storage versus your own site, sharing settings and file size — so the PDF opens on the first try.
Where to host the PDF
| Where | Pros | Watch out for |
|---|---|---|
| Google Drive | Replace the file and keep the same link | Sharing set to “Anyone with the link” |
| Dropbox or OneDrive | Quick, familiar, opens without signing in | Create a public view link |
| Your own website | A short permanent address on your domain | Needs hosting or a site builder |
Cloud links are long and make the pattern denser. If the code will be small — on a label or a warranty card — host the file on your site with a short address such as site.com/manual.pdf.
Preparing the file
- Compress the PDF to 5–10 MB: on mobile data a heavy file loads slowly and people close the tab.
- Make the first page useful — it is what people see while the rest loads.
- Add a date to catalogues and price lists so readers know the information is current.
Test the code on a phone where you are not signed in to Google or Dropbox. The most common mistake is a file shared only with its owner, so people see an access request instead of the document.
Where it helps
- A manual on packaging or a warranty card.
- A catalogue and price list at a trade-show stand.
- A menu that already exists as a PDF.
- Conference handouts and presentations.
- A customer leaflet or contract at the front desk.
