What is PDF/A?
PDF/A is an ISO-standardized subset of PDF (ISO 19005) created specifically for the long-term digital preservation of electronic documents. While a regular PDF can reference external fonts, include JavaScript, or depend on system resources that may not exist in the future, a PDF/A file is entirely self-contained. Every font, color profile, and resource needed to render the document is embedded within the file itself, ensuring it will display identically on any system at any point in the future.
The two most common conformance levels are PDF/A-1b and PDF/A-2b. PDF/A-1b (based on PDF 1.4) provides the baseline level of compliance — it guarantees reliable visual reproduction and is the most universally accepted version by courts, government agencies, and archives worldwide. PDF/A-2b (based on PDF 1.7) builds on this foundation by adding support for JPEG2000 compression, transparency layers, and the ability to embed other PDF/A files as attachments, making it ideal for more complex modern documents while maintaining full archival compliance.

Frequently Asked Questions
What is PDF/A?
PDF/A is an ISO-standardized version of PDF specifically designed for long-term digital archiving. Unlike regular PDFs that may depend on external fonts, color profiles, or multimedia, PDF/A files are entirely self-contained - all fonts are embedded, colors are standardized, and no external dependencies exist. This ensures the document will look identical decades from now.
Which PDF/A version does this converter produce?
Our converter supports PDF/A-1b and PDF/A-2b conformance levels. PDF/A-1b (based on PDF 1.4) ensures basic visual preservation and is the most widely accepted standard. PDF/A-2b (based on PDF 1.7) adds support for JPEG2000 compression, transparency, and embedded files while maintaining archival compliance.
Why should I convert my PDFs to PDF/A?
PDF/A ensures your documents remain readable and visually identical for decades regardless of what software or operating systems exist in the future. Regular PDFs can rely on system fonts or external resources that may become unavailable. PDF/A eliminates these dependencies, making it the required format for legal archives, government records, and regulatory compliance.
Will converting to PDF/A change my file size?
PDF/A files are typically slightly larger than standard PDFs because all fonts and color profiles are embedded directly in the file. The size increase is usually modest (5-20%) and is a worthwhile trade-off for guaranteed long-term readability and compliance.
Can all PDFs be converted to PDF/A?
Most standard PDFs convert to PDF/A successfully. However, PDFs with embedded multimedia (audio, video), JavaScript, or encryption may require modification during conversion since PDF/A prohibits these features. Our converter handles these cases automatically, removing non-compliant elements while preserving all visual content.
Is PDF/A conversion reversible?
PDF/A files are standard PDF files with additional compliance constraints. You can open and use them like any regular PDF. However, if you edit a PDF/A file with a standard PDF editor, the edits may break PDF/A compliance. To restore compliance after editing, simply run the file through our converter again.
Who requires PDF/A format?
Many institutions mandate PDF/A including courts (for e-filing), government agencies (for public records), libraries and archives (for digital preservation), financial regulators (for audit documents), healthcare organizations (for patient records), and the European Union (for official documents). Requirements vary by jurisdiction and industry.
Is this PDF/A converter really free?
Yes, 100% free with no limits. Unlike iLovePDF or SmallPDF that restrict free users to a few conversions per day and require paid subscriptions, you can convert unlimited PDFs to PDF/A - no registration, no watermarks, no hidden fees. All processing happens in your browser for complete privacy.
