Where should I host my PDF for a QR code?

You can host a PDF anywhere that provides a direct public URL: your own web server, Google Drive (Anyone with the link), Dropbox (direct link with ?dl=1), Notion, or a CDN. The key is that the link must be publicly accessible without requiring sign-in.

Can I update the PDF without changing the QR code?

With a static QR code, no — the URL is fixed. With a dynamic QR code from Online-QR, you can update the destination URL at any time. This means you can replace or update the PDF document without reprinting any QR codes.

Will the PDF open directly or prompt a download?

This depends on the server configuration and the browser or app used. Most mobile browsers open PDFs inline. You can control this behavior with the Content-Disposition HTTP header on your server.

Is there a file size limit for PDF QR codes?

There is no file size limit for the QR code itself, as it only encodes the URL. However, large PDFs take longer to load on mobile connections. As a best practice, compress PDFs to under 5MB for a good user experience.

What is a PDF QR Code?

A PDF QR code is a URL QR code that points to a hosted PDF file. When scanned, the phone opens the PDF in its native viewer or browser. This is an effective way to distribute documents without printing: product manuals, safety data sheets, academic papers, real estate brochures, digital catalogs, and more. Instead of printing hundreds of copies, you print one QR code and link to a digital document that can be updated without changing the code.

How to Create a PDF QR Code

1
Upload your PDF to a web server, Google Drive (with share link set to "Anyone with the link"), Dropbox, or any cloud storage with a public direct link
2
Call the API with your PDF URL: https://api.online-qr.com/v1/make-qr?data=https://yourdomain.com/documents/manual.pdf
3
Print the QR code on product packaging, brochures, or signage — scanning opens the PDF directly on the user's device
