The complete guide to PDF to PDF/A Converter
Last updated June 1, 2026PDF/A is an ISO-standardized version of PDF designed for long-term archiving. It guarantees that a document will render identically in 100 years by embedding all fonts, color profiles, and metadata it needs — no reliance on external systems. Governments, courts, universities, and regulated industries (healthcare, finance, legal) often mandate PDF/A for records submissions.
Converting a standard PDF to PDF/A with Convertify's tool handles the most common compliance requirements: embedding any referenced fonts, attaching color profiles, and removing external content references (JavaScript, audio, video) that aren't permitted in PDF/A. The visual appearance is preserved; only archival-incompatible elements are stripped or embedded.
Common submission requirements: the European Court of Human Rights requires PDF/A-1b; the US federal courts' ECF system accepts PDF/A-1; many EU government portals require PDF/A-2a or PDF/A-3.

Real-world scenarios
Court filings requiring PDF/A
Federal courts and many state courts in the US and EU require PDF/A for electronic case filing. Convert your brief or exhibit before submission to avoid rejection from the court's document management system.
Government portal submissions
EU tax authorities, land registries, and licensing bodies increasingly require PDF/A. The conversion ensures your application PDF renders identically on their systems and satisfies archival mandates.
Corporate records archival
Finance and legal departments archiving contracts, board minutes, and compliance documents in a DMS that requires PDF/A can convert existing files before ingestion.
Troubleshooting and edge cases
My PDF fails PDF/A validation even after conversion.⌄
Some PDFs have deeply embedded non-compliant elements (encrypted streams, embedded multimedia) that the converter can't fully resolve. Run the output through a PDF/A validator (VeraPDF is free and widely used) to identify exactly which compliance violations remain. For complex failures, Adobe Acrobat Pro's Preflight tool offers more surgical fix options.
The PDF/A file is larger than the original.⌄
Expected — embedding all fonts and color profiles increases file size. For 5-page contracts, the increase is minimal (10-20%). For image-heavy documents, embedding a color profile adds more. If size is an issue, compress the PDF first, then convert to PDF/A.
