How to make a QR code for a PDF
The code holds the address of the PDF, not the PDF itself.
In short
A QR code holds a few kilobytes at most, far too little for a PDF. Upload the PDF somewhere that gives a permanent public link — your website, or a cloud drive set to “anyone with the link” — then make a QR code of that link. Test it on a phone that is not signed into your account.
Key takeaways
- Host the PDF, then encode its link.
- Use a link that will not change.
- Test on a phone that is not logged into your account.
Why the PDF cannot go in the code
The largest QR code holds about 3 KB of data. A one-page PDF is usually tens or hundreds of kilobytes. So the code always stores an address, and the phone downloads the file from there.
Where to host the PDF
- Your own website: the most durable link, under your control.
- A cloud drive (iCloud Drive, Google Drive, Dropbox) shared as “anyone with the link”.
Keep it working
If you replace the PDF, keep the same address, or the printed codes will lead nowhere. Avoid temporary file-sharing links that expire.
Privacy
Anyone who scans the code can download the file, and pass the link on. Do not use a QR code for a document that should stay private.
