What is PDF/A and why do I need it?

PDF/A is an ISO standard for long-term archiving of PDF documents. It ensures the file is self-contained and will render identically in the future, making it required for legal, government, and archival submissions.

Which PDF/A level should I choose?

PDF/A-2b is recommended for most uses as it supports modern PDF features. Choose PDF/A-1b for maximum compatibility with older systems, or PDF/A-3b if you need to embed other file types.

Will the PDF look different after conversion?

The visual appearance should remain the same. PDF/A conversion may adjust color profiles and embed fonts to ensure the document is fully self-contained.

How to convert a PDF to PDF/A for archiving

PDF/A is the ISO standard for long-term document archiving. It embeds all fonts, disallows external dependencies, and requires device-independent colour — guaranteeing the file renders the same decades from now.

Pick a level: PDF/A-1, A-2, or A-3 (default A-2). A-1 is the strictest; A-3 supports embedded attachments.
