Extract PDF Pages: First extract the QR code from your PDF file.
Identify and Decode QR Code: After extracting the images or pages containing the QR code, we’ll decode the information embedded in it.

This can also be done using DU (Document Understanding)

If u required code please let me know

Welcome to the forum @Melbin_Antu2 :party_popper:

Regarding your usecase,

  1. Use Extract Images From PDF activity to get all the images from the PDF.
    Activities - Extract Images From PDF

  2. Now install UiPathTeam.Barcode package.

    The image shows the "Manage Packages" window in UiPath Studio, displaying installed project dependencies, including one for barcode activities. (Captioned by AI)

For Extraction, Check out UiPath.PDF.Activities.

After Installing the package, Use Read PDF With OCR Activity. Pick an OCR(Preferably Tesseract OCR if you want reliability)

Assign the output to a variable(In this case the entire page your QR Code is located)

Use .Contains() if youre extracting multiple pages.

Finally use Regex to extract exactly what youre looking for. (System.Text.RegularExpressions.Regex.Match(inputText, pattern).Value)

Extracting QR codes from PDFs can be tricky since they are often embedded as images rather than text elements.
If you are looking for a straightforward way to handle this without building a complex OCR workflow in UiPath, you could try using a dedicated PDF extraction tool. There are several lightweight web-based utilities that specialize in pulling images or specific data from PDF files. Once you have the QR code image extracted, passing it through a standard barcode reader activity becomes much more reliable.
Another option is to use the “Export PDF Images” activity in UiPath first, and then point your QR scanner at the resulting folder. That usually saves a lot of headache compared to trying to read the QR code directly from the document page.
