How to add a QR Code to a PDF

In most practical applications, you not only want to share a PDF through a QR Code, but you also want to embed the code within the PDF itself. This is particularly useful for digital invoices, brochures, contracts, whitepapers, or receipts where you want the reader to scan the QR Code to perform an action such as making a payment or visiting a website.

Step 1: Create and download your PDF QR Code

First, generate your PDF QR Code using Uniqode. Download the QR Code image in a suitable format. Make sure you test the QR Code before inserting it into the PDF.

Step 2: Open your PDF in an editing tool

Next, open the PDF where you want to place the QR Code using a PDF editor or design tool such as Adobe Acrobat, Google Docs (import the PDF and re-export it), Microsoft Word (insert the QR Code image and save as PDF), Canva, or similar design tools. 

Step 3: Insert and position the QR Code in the PDF

Upload or insert the downloaded QR Code image into the PDF and position it where it’s easy to scan. 

Common placements include:

• The footer or corner of an invoice or receipt
• A dedicated “Scan for more details” section in brochures
• The last page of contracts or manuals
• The cover or final page of whitepapers and reports
  

Ensure the QR Code is large enough to scan easily, especially if the PDF may be printed later.

‍

Step 4: Save, test, and share the PDF

Now that the QR Code is positioned correctly, it is time to save the PDF and test the QR Code again on both desktop and mobile devices. Once you have tested the QR Code, your PDF is ready to be shared or printed.

Since the PDF QR Code is dynamic, you can always update the content that it links to later without having to change or resend the PDF itself. 

Top PDF QR Code use-cases for power users

Are you looking to level up your PDF QR Codes? Imagine a QR Code scan that:

• Leads to a specific section in a PDF
• Adapts to your user's language
• Switches PDF based on the time of day

At Uniqode, we constantly hear from our customers about the innovative ways they use QR Codes to make their jobs easier and deliver a stellar user experience. 

Here are some of the ways our power users use a PDF QR Code:

⚡ Point users to a section within a PDF

What: While most QR Codes point users to the beginning of a PDF file, as a power user, you may want to link to a particular page or a section in the PDF. A section-specific PDF QR Code helps with this exact use case.

How: The easiest way to do this is by using Google Drive:

1. 1. Upload your PDF file to Google Drive. Then open the PDF file, click Share, and set it to be accessible to everyone as a Viewer.

1. 2. Highlight the specific section or heading and add a comment. Then click the three-dot menu on the comment to select Link to this comment. You will now have the URL to the comment copied to the clipboard automatically.

1. Open Uniqode's portal, and create your PDF QR Code with this link. The workflow remains the same.

⚡ Create a location-based multi-language PDF QR Code

What: You can create a multi-language PDF QR Code that dynamically switches PDFs based on the user's location.

‍

For example, a PDF QR Code that links to your product’s English user manual can point to different PDFs based on the user's country. So, when scanned, a Japanese user sees the Japanese PDF, while an American user sees the English PDF, from the same QR Code.

‍

How:

1. 1. Log in to Uniqode, navigate the QR Code creation menu, and select PDF QR Code.

1. 2. Toggle the Multi-language support option. Add the languages or locales and upload the respective PDFs for each. Uniqode automatically shows the relevant PDF based on the user's device locale.

⚡Pro Tip: Set a default PDF for users whose device locale does not match your localized URLs. These users will be automatically redirected to the default version.

3. Customize your QR Codes with your brand logo, colors, and shapes. Then, hit next and download the code in your desired format.

1. 🚨Pro tip: You can enable location tracking of your QR Code from the customization window to track the GPS location of your PDF viewers.

⚡ Create a time-based PDF QR Code

What: Time-based QR Codes are ideal for changing content based on the time of day. For example, a restaurant might want to display a special discounted menu during happy hours.

How:

1. 1. Log in to Uniqode, go to "+Create," and select "Smart Rules."

1. 2. You can choose single or multiple rules per your use case to create a Smart QR Code for PDF. Choose your rule and enter the values. For this example, I am using a time-based rule where I have specified the time and the content I want users to see when scanned within the window. There’s also a box to insert an alternative resource you want users to see should they scan outside the time window.

1. 3. Customize your QR Codes with your brand logo, colors, and shapes. Then, hit Next and download the code in your desired format.

1. 💡Pro tip: Time-based QR Codes are just one example of the available "Smart Rules." You can apply other rules for more customization:

What are the benefits of a PDF QR Code?

Using a QR Code to share PDFs goes beyond basic document access. Here are the key benefits:

• Secure confidential PDFs (contracts, offer letters, internal docs) with password-protected QR Codes. Only authorized users can access the file after scanning.
• Use gated PDF QR Codes to collect user data (e.g., email addresses) before granting access to premium content such as reports or whitepapers. Manage access, update files, and track performance through dynamic QR Code controls.
• Track scans, locations, devices, and engagement to measure performance and adoption. Use scan data to verify content reach and compliance (e.g., training material distribution).
• Retarget users who scan your PDF QR Code with ads on Google and Meta. Build custom audiences based on actions like downloads, views, or abandoned interactions.
