- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Using Acrobat Preflight to embed an audit trail or process a PDF document.
- Observed behavior
- The PDF version is unexpectedly downgraded to version 1.3 after applying the Preflight profile.
Always create a backup copy of your original PDF document before testing different Preflight profiles to prevent accidental loss of document features or formatting.
Adjust Preflight Profile Compatibility Settings
Identify and modify the specific fixup or 'Convert to Standard' setting in your Preflight profile that forces PDF 1.3 compatibility.
Preflight profiles consist of multiple automated checks and fixups. If a profile is designed for older commercial printing standards (such as PDF/X-1a), it will automatically flatten transparencies and downgrade the document to PDF 1.3.
To stop the downgrade, you must review the specific profile you are running and disable the conversion fixups.
Open your document in Adobe Acrobat, navigate to the 'Tools' menu, and select 'Print Production'. Click on 'Preflight' in the right-hand pane.
In the Preflight dialog box, locate the profile you are currently using. Select it and click the 'Edit' button (or the wrench icon) to view its properties.
Check the 'Convert to Standard' section on the left side of the profile editor. If it is set to a standard like PDF/X-1a, change it or disable the standard conversion.
Navigate to the 'Fixups' section of the profile. Look for any actions related to 'Flatten transparency' or 'Save as PDF 1.3'. Uncheck or remove these fixups from the active profile.
Save your modified profile under a new name to keep the original intact. Run this new profile on a copy of your PDF to ensure the audit trail embeds without altering the 1.6 version.

Frequently Asked Questions
What is the difference between PDF version 1.3 and 1.6?
PDF 1.3 is an older standard that does not support advanced features like native transparency and layers, often used for legacy commercial printing. PDF 1.6 supports advanced multimedia, 3D artwork, and interactive features like audit trails.
Why would a Preflight profile force an older PDF version?
Preflight profiles are often designed for specific commercial printing standards, such as PDF/X-1a. These standards require flattening transparency and saving the document as PDF 1.3 to ensure ultimate print reliability across older hardware.
How do I check the current version of my PDF?
In Adobe Acrobat or WPS PDF, you can usually find this by going to 'File', selecting 'Properties' or 'Document Properties', and looking at the 'PDF Version' listed under the Description or General tab.
