- 1
Host your PDF online
Host the PDF on your website or a file-sharing service and set permissions for your intended audience. QR Forge does not upload or host files.

Paste the PDF URL
Enter the hosted file or share URL. Check it on a device without your account to confirm the intended audience can access it.

Design, download, and deploy

Frequently asked questions
Use Google Drive's sharing controls to copy a link and choose access for your intended audience. The link may open a preview rather than a direct download; test it without your own signed-in account.
It depends on the scanner, browser, file host, and sharing permissions. Test the link and QR code on the devices your audience uses.
The QR keeps the same URL. If your host lets you update the file while preserving that URL and its permissions, the link can show the new version. Check the host's behavior and test it after updating.
QR Forge encodes the URL, not the PDF file. Your host controls file-size limits; the URL itself must fit in the QR code. Larger files may take longer to load on mobile.
Your file host or PDF may require a password or sign-in. QR Forge only encodes the URL and does not manage access; test the experience with your intended audience.
Functionally identical — a PDF QR is simply a URL QR whose destination happens to be a PDF file. We list it separately so you can quickly find it by use case.
