Does maintool host my PDF?

No. You provide a URL to a file you already host. maintool only creates a QR for that link, locally in the browser.

What URL should I use?

A direct HTTPS link that opens the PDF without a login wall works best for public sharing.

They need network access when scanning. After opening, they can save the PDF on their device if the viewer allows it.

No. The URL is processed only in your browser to build the QR image.

Your data never leaves your browser — all QR codes are generated locally.

A PDF QR code is a URL QR that points to a publicly reachable PDF file. Scanning opens the document in the phone’s browser or PDF viewer.

Useful for product manuals, event programs, brochures, and catalogs when printing the full document is impractical.

maintool only encodes the URL you provide — in your browser. We never receive the PDF file itself.

The QR only stores the link. Keep the file on reliable hosting. If the URL changes, regenerate the code.

Do not put confidential documents on a public URL. maintool does not upload your PDF; link security is your responsibility.
