PDF to PDF/A Converter – Free Online ISO 19005

Frequently asked questions

What is the difference between PDF and PDF/A?

PDF/A is a restricted subset of PDF designed for long-term archiving. It requires embedded fonts, defined color spaces, XMP metadata, and prohibits encryption, JavaScript, and external references. A regular PDF may rely on external resources that could become unavailable over time.

Which PDF/A version does this tool produce?

This tool produces PDF/A-1b, the most widely accepted version for basic visual conformance. It adds all required XMP metadata and OutputIntent.

Is the output fully ISO 19005 certified?

The tool adds all required PDF/A-1b metadata and removes non-conforming elements. For documents originating from standard sources (Word, LibreOffice, virtual printers) the result passes most validators. For ISO-certified validation we recommend verifying with veraPDF at demo.verapdf.org.

Why is PDF/A required by public administrations?

Public administrations in Italy, the EU, and many other jurisdictions require PDF/A for official document submissions to guarantee that files remain readable and legally valid over time, independent of software versions.

Can I convert an encrypted PDF to PDF/A?

PDF/A does not allow encryption. If your PDF is password-protected, the tool will attempt to process it but the result may not be fully compliant. Unlock the PDF first using the PDF Unlock tool.

Does the conversion change the visual appearance of the document?

No. The visual content of the document is preserved. Only metadata and conformance markers are added or modified.

Is my PDF uploaded to a server?

No. The entire conversion happens in your browser. Your document never leaves your device.

What is veraPDF?

veraPDF is the industry-standard open-source PDF/A validator, developed with support from the PDF Association and the European Commission. You can use it for free at demo.verapdf.org to verify your converted file.
