## Summary
A QR code cannot store a PDF file — a QR code holds at most 2,953 bytes, while a one-page PDF is typically 50,000 or more. What a PDF QR code stores is the link to a hosted file. Upload the PDF to your website or a cloud drive, then encode that public URL.

## Where to put the file so the link survives
The code is only as permanent as the address behind it. Ranked by how long the link tends to last:

| Location | Link stability | Watch out for |
|---|---|---|
| Your own domain | Best | Keep the path stable through site redesigns |
| Google Drive | Good | Set sharing to Anyone with the link, or scanners hit a login wall |
| Dropbox | Good | Change `?dl=0` to `?raw=1` to open rather than download |
| OneDrive / SharePoint | Mixed | Corporate tenants often block anonymous access |
| A free file host | Poor | Files are deleted after a period of inactivity |

Whatever you choose, test the link in a private browsing window on mobile data. That reproduces what a stranger's phone sees — no cookies, no session, no company VPN.

## When a web page is the right answer instead
PDFs are fixed-width documents designed for paper. Phones are not paper. If your PDF is a menu, a price list, a brochure or an event programme, a simple mobile web page will outperform it every time: no download, no pinch-zoom, no PDF viewer that opens in a random app.

If instead you are producing a document and need a code [inside the PDF itself](/qr-code-pdf/), that is a different job.

Keep the PDF when the document genuinely needs to be a document — a warranty, a technical datasheet, a form to print and sign, a certificate, an instruction manual people will save. Otherwise, build a page and link to that.

## Three checks before the code goes to print
1. **Size.** Under 5 MB. A 40 MB brochure over a weak mobile signal is a scan that gets abandoned halfway.

2. **Metadata.** PDF properties carry the author name, the software used and sometimes the original file path. Clear them before publishing.

3. **Direct link.** The URL should open the file itself, not a preview page with a download button behind another click.

## Frequently asked questions
### Can a QR code contain the actual PDF file?
No. The absolute maximum any QR code can hold is 2,953 bytes, which is smaller than almost any real PDF. The code stores a link to the hosted file.

### How do I make a QR code for a PDF on Google Drive?
Open the file in Drive, choose Share, set access to Anyone with the link, copy the link and paste it into the generator. Test it in a private window before printing.

### Will the code break if I replace the PDF?
Only if the URL changes. Upload the new version at exactly the same path and the existing printed code keeps working — which is a good reason to host on your own domain.

### Can people scan it without internet?
No. The code carries a link, and following a link needs a connection. If offline access matters, encode the content as plain text instead.
