About This Tool
PDF to PDF/A converts your PDF documents to PDF/A format, the ISO standard for long-term document archiving. PDF/A ensures that documents will be viewable and reproducible for decades.
Choose from PDF/A-1b (basic conformance), PDF/A-2b (recommended, supports transparency), or PDF/A-3b (allows embedded files). The tool embeds fonts and flattens transparency as needed.
All conversion happens locally in your browser, ensuring your documents remain private.

Choose PDF/A-2 for documents with transparency or layers. PDF/A-1 is stricter but more universally accepted by archives.
