Free PDF QR Code Generator

This code links to a document at an address you already control. Hosting a PDF for you, so you can swap the file behind a fixed code, is a separate account feature.

What should the code do?

Point at a PDF you already host.

This encodes a link to a document you already host. Replacing the file behind a stable code is a hosted feature that needs an account.

Design

Code colour
On white. Always clear.
Background
On white. Always clear.
Module shape

Higher levels recover from more damage but make the code denser. A centred logo needs Q or H.

Printed below the symbol. Long text wraps onto up to four lines.

Captions and call-to-action bars are drawn outside the code, so the four-module quiet zone stays clear. Every download contains exactly the artwork shown in the preview.

Upload your logo

Add your brand to the centre of your QR code, or place it above or below. Always test the final code before printing.

How to make this code

  1. 1

    Upload your PDF wherever you normally host files and copy its public address.

  2. 2

    Paste that address here and check it opens in a private browser window — if it needs a login, the code will not work for customers.

  3. 3

    Print the code with a caption saying what the document is.

Frequently asked questions

Can I replace the PDF later?

Only if you keep the same file address on your own host. The code cannot be edited once printed, because the address is inside the pattern.

Does the file get uploaded to you?

No. This page never receives your document; it only encodes the address you paste.

Which download format is best for printing?

SVG is a true vector file: a printer or designer can scale it to any size without losing edge quality, so it is the best thing to hand to a print shop. The PDF here places a high-resolution image of the same artwork on the paper size you choose, which suits home and office printing at that size. PNG is for screens and for systems that only accept images. Whichever you pick, print one copy at the final size and scan that copy yourself before ordering a batch — no format can guarantee a scan on a given printer, material or light.
