Frequently asked questions

What is PDF/A and why do I need it?
PDF/A is an ISO-standardised subset of PDF designed for long-term archiving. It embeds all fonts, colour profiles, and metadata directly in the file so it renders identically on any system, now and in the future.
How do I convert a PDF to PDF/A for free?
Upload your PDF — the tool converts it to PDF/A-1b or PDF/A-2b format, embedding all required elements. Download the compliant archive file.
What is the difference between PDF/A-1, PDF/A-2, and PDF/A-3?
PDF/A-1 is the strictest (no embedded files). PDF/A-2 adds support for JPEG 2000, transparency, and optional content layers. PDF/A-3 allows embedding of any file type as an attachment. PDF/A-2 is recommended for most use cases.
Who requires PDF/A format?
Government agencies, courts, healthcare institutions, and financial regulators in many countries require PDF/A for official submissions and records retention. ISO 19005 is widely referenced in compliance frameworks.
Can I convert a scanned PDF to PDF/A?
Yes. Scanned PDFs are converted to PDF/A with the scan embedded as a compliant image. If text searchability is needed, run OCR first, then convert to PDF/A.
Does PDF/A conversion change the visual appearance?
No. The document looks identical. The conversion only ensures all resources are self-contained and non-compliant features (like JavaScript, encryption, and external links) are removed.
