QR code to open a PDF
A QR can't store a PDF inside it: it stores the address where the file is hosted. Scanning it makes the phone open that address and the document appears on screen. It is the most direct way to get from a piece of paper, a label or a sign to a long document nobody would want printed.
It's used for instruction manuals, spec sheets, catalogues, price lists, event programmes, assembly guides, and any document you need at hand without carrying it around.
Any web address. We add https:// for you.

How it works
- 1
Upload the PDF to a public address
Your own site or a storage service. It has to be reachable without asking for permission: if it opens a sign-in screen, the code is useless.
- 2
Copy the direct link to the file
It should point at the PDF, not at a folder or an intermediate page. Storage services usually have a share-by-link option that needs to be set so anyone with the link can view.

Generate, test and download
Scan the code from a phone that isn't yours and isn't signed in. It's the only way to catch a file that's restricted without you realising.
The mistake that ruins half of these codes
The most frequent failure has nothing to do with the code and everything to do with file permissions. Whoever generates it is signed in, scans the code on their own phone, sees it open and assumes it works. When a customer scans it, a screen appears asking for access.
The correct test is opening the link in a private window or from someone else's phone. If the PDF appears without asking anything, the code is fine. This is also why a personal work folder is a poor choice: any future reorganisation changes the address and breaks every printed code.
When a PDF isn't the best idea
On a phone, a PDF laid out for A4 looks like a miniature sheet of A4. The reader has to zoom and drag to read each paragraph. For a manual consulted occasionally that's tolerable; for something people will read end to end, like a restaurant menu or a catalogue, a web page that adapts to the phone gives a far better result.
Weight matters too. A twenty-megabyte catalogue with high-resolution photos takes a while to open on mobile data, and some people give up first. If the document is heavy, keep a light version for screens and save the high-resolution one for whoever asks.
And a deeper consideration: the PDF stays the same forever, but the address it lives at can change. If the document will be updated, point the code at a stable address on your own domain that always leads to the current version, rather than at a file with the version number in its name.
