How to Create and Validate PDF/A-2a or PDF/A-3a Files
Question details
The user needs to create and verify PDF/A-2a or PDF/A-3a documents but is unable to find the required presets in their PDF creation software.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to generate or validate a PDF document to meet specific PDF/A-2a or PDF/A-3a long-term archiving standards.
- Observed behavior
- Acrobat and Distiller display limited PDF/A presets, making it difficult to find the necessary tools to create or verify the PDF/A-2a and PDF/A-3a conformance levels.
Verify your exact version of Adobe Acrobat, as full support for PDF/A-2a and PDF/A-3a standards depends heavily on your software release and the currently installed Preflight libraries.
Use Preflight Profiles in Acrobat to Convert and Validate PDF/A
The most reliable way to achieve PDF/A-2a or PDF/A-3a compliance is through Acrobat's built-in Preflight tool, which contains specialized profiles designed for PDF standards.
Standard PDF presets often do not cover the strict structural tagging required for the 'a' (accessible) conformance level of PDF/A-2 and PDF/A-3. Using the Preflight tool allows you to analyze an existing PDF, inject the necessary metadata, and force conformance.
Go to the 'Tools' menu in Adobe Acrobat, select 'Print Production', and then click on 'Preflight'.
In the Preflight dialog box, click the 'Libraries' drop-down menu at the top and ensure that 'PDF Standards' is selected.
Expand the 'PDF/A' section. Look for the profiles named 'Convert to PDF/A-2a' or 'Convert to PDF/A-3a' depending on your archiving requirement.
Click the 'Analyze and fix' button at the bottom right. Acrobat will prompt you to save the new file, convert the document to the selected standard, and provide a validation report.
Use Specialized Third-Party PDF/A Validation Tools
If Acrobat Preflight is unavailable or fails to validate the document correctly, you can use specialized, independent validation software.

Frequently Asked Questions
What is the difference between PDF/A-2a and PDF/A-3a?
PDF/A-2a requires exact visual rendering and structural document tagging (for accessibility) based on the PDF 1.7 standard. PDF/A-3a includes the exact same requirements but also allows you to embed files of any format (such as XML, CSV, or CAD files) within the PDF document.
Why are PDF/A presets missing in Adobe Distiller?
Adobe Distiller is an older technology designed primarily for converting PostScript files to standard PDFs. It does not support modern PDF/A structural and accessibility tagging (the 'a' conformance level). You must use Acrobat's Preflight tool instead.
Can I upgrade a PDF/A-1b file to PDF/A-2a?
Directly upgrading is difficult. While you can convert the format version to PDF/A-2, achieving the 'a' (accessible) conformance level requires the document to have logical structural tags (headers, paragraphs, alt text). If the original PDF/A-1b lacks these tags, they must be added manually before passing PDF/A-2a validation.
