How to use PDF to PDF/A
- Keep the original PDF as your source of record.
- Open PDF to PDF/A and select the document.
- Run the conversion and download the generated file.
- Validate the result with an independent PDF/A validator and check fonts, metadata, attachments and visual appearance.
Best practices for reliable results
- Keep an untouched backup of the source file.
- Only process documents you have permission to use and share.
- Review every page of the output, not just the first page.
- Check text, layout, page order, links, fields and images where relevant.
- For important work, compare the output with the original before distributing it.
Limitations to know
A conversion result is not proof of full PDF/A compliance. Archival rules can vary by PDF/A profile and organization; validate independently before using the file for legal or regulated archiving.
