- Product
- PDF Reader
- Device & OS
- not provided
- Scenario
- Reviewing the document properties of a scanned PDF file.
- Observed behavior
- The document properties indicate the PDF version is 1.3 or Acrobat 4.x, regardless of the version of the PDF reader being used to open it.
Verify the original scanning software installed on your computer, as you may need to adjust its output settings to generate a newer PDF version.
Check the PDF Producer and Scanner Settings
The PDF version is determined by the software that creates the file, not the reader. Identifying the PDF producer helps you locate which software settings to change.
A PDF reader is only responsible for displaying the file and cannot edit the original version property by itself. To fix this, you need to adjust the settings in the software that originally created the PDF.
Open the scanned PDF in your reader and press Ctrl+D (or navigate to File > Properties) to open the Document Properties dialog box.
Locate the 'PDF Producer' field within the properties window. This value indicates the exact HP software or engine that created the file.
Open the HP scanning application on your computer, navigate to the output or save settings, and check if there is an option to select a higher PDF version for future scans.
Upgrade the PDF Version by Resaving
If the scanner software cannot output a newer version, you can convert or resave the file using a dedicated PDF editor.
Upgrade and Manage PDF Versions with WPS Office
WPS Office provides a comprehensive PDF toolset that allows you to effortlessly open legacy PDFs, review document properties, and save them into modern, compatible formats.
- 1. Open your PDF: Launch WPS Office and open your scanned version 1.3 PDF file using the built-in PDF reader.
- 2. Check Properties: Click on the 'Menu' button, select 'Document Properties', and review the current version and PDF producer.
- 3. Save as Modern PDF: Go to 'Menu', select 'Save As', and save the document to generate a modernized PDF file with updated properties.

What does PDF Producer mean in the document properties?
The PDF Producer field indicates the specific software application, driver, or hardware engine (such as HP scanning software) that generated the PDF file.
Is PDF version 1.3 still safe and supported to use?
Yes, PDF version 1.3 (associated with Acrobat 4.x) is an older but universally supported standard. However, newer versions offer improved security features, better compression, and enhanced interactive elements.
How do I change the default PDF version generated by my scanner?
You need to access the settings or preferences menu directly within your scanning software on your computer. Look for advanced output, file format, or destination settings. Note that the available options will depend on the age and capabilities of your specific scanning software.
