What is PDF/A?

PDF/A is an ISO-standardized version of PDF designed specifically for long-term document archiving. Unlike regular PDFs that might rely on external fonts, dynamic content, or features that could become obsolete, PDF/A is self-contained and future-proof. Every element needed to render the document correctly is embedded within the file itself.

The "A" stands for Archive. Documents in PDF/A format are guaranteed to look exactly the same whether opened today or fifty years from now. This is critical for legal documents, medical records, financial statements, and any document that must remain accessible and authentic over time.

Various PDF/A conformance levels exist (PDF/A-1b, PDF/A-2b, PDF/A-3b), with PDF/A-2b being the most common modern standard. It allows compression, layers, and transparency while maintaining archival integrity.

Step-by-Step: Converting to PDF/A

  1. Upload your PDF — Drag your standard PDF into the upload area.
  2. Select PDF/A version — Choose the conformance level required (PDF/A-1b, PDF/A-2b, or PDF/A-3b).
  3. Process conversion — Fonts are embedded, metadata standardized, and non-compliant features removed or converted.
  4. Download result — Your PDF/A compliant document is ready for archiving or submission.

PDF/A Conformance Levels

PDF/A-1b

Basic conformance level based on PDF 1.4. Most restrictive—no transparency, no layers, no JPEG2000. Maximum compatibility with older systems.

PDF/A-2b (Recommended)

Based on PDF 1.7. Allows transparency, layers, JPEG2000, and better compression. Best balance of features and compatibility.

PDF/A-3b

Same as PDF/A-2 but allows embedding arbitrary file attachments. Use when you need to include source files or supporting data.
