How to turn a PDF into a QR code (and update it without reprinting)

5 min read · Updated 7 November 2026

A PDF QR code is the quickest way to put a brochure, price list, manual or menu in someone's hand without printing pages. There are two ways to do it, and the right one depends on whether the file will change.

Option 1: upload the PDF and let us host it

Choose the PDF type, upload the file (up to 20 MB) and add a title. The code opens a short page with your title and an Open button, or the PDF straight away if you prefer. Because the code points at a page we host, you can upload a new version later and every printed code shows it.

If the PDF lives on your website, Google Drive or Dropbox, paste its public link instead. Check it opens in a private browser window without asking anyone to sign in. Google Drive links set to 'Restricted' are the most common reason PDF codes fail.

Make the PDF easy to read on a phone

  • Export with 'reduce file size'. Under 3 MB opens in seconds on mobile data.
  • Use a single column and large type. Multi-column print layouts need pinching and zooming.
  • Put the important page first. People rarely scroll past page three on a phone.
  • For a restaurant menu, consider the menu type, which builds a phone-friendly menu page instead of a PDF.

Static or dynamic?

A hosted PDF is always a dynamic code, so you can replace the file and see scan counts. A plain link to a PDF elsewhere can be static, but if that link changes, the printed code breaks. If the document will be updated, upload it.

  1. Upload the PDF or paste its public link. Up to 20 MB; smaller is faster.
  2. Add a title and choose how it opens. A short page first, or the PDF straight away.
  3. Style the code and add a caption. 'Scan for the full price list' says what people get.
  4. Save, download and test on mobile data. Open it on a phone that isn't on your WiFi.

Frequently asked questions

Questions

Can I change the PDF after printing the QR code?

Yes, if you uploaded it. Replace the file and the same code opens the new version.

Is a PDF QR code free?

Yes. Hosted PDFs count as dynamic codes, and the free plan includes free dynamic codes and 25 MB of storage.

Why does my PDF code ask people to sign in?

The link points to a private file. Make the file public or 'anyone with the link', or upload it to us instead.
