PDF/A is an ISO standard for long-term archiving of electronic documents

About PDF to PDF/A Converter

Our free PDF to PDF/A converter transforms standard PDF documents into ISO-compliant archival format, ensuring your files remain accessible and readable for decades to come. Whether you need PDF/A-1b, PDF/A-2b, or PDF/A-3b compliance, this tool handles the conversion seamlessly with full font embedding and resource encapsulation.

PDF/A format is the international standard (ISO 19005) specifically designed for long-term digital preservation of electronic documents. Unlike regular PDFs, PDF/A files are self-contained, meaning all fonts, color profiles, and resources are embedded directly within the document, eliminating dependency on external systems.

This online PDF/A conversion tool processes your documents entirely in the browser and server pipeline with no permanent storage. Your original document layout, images, and formatting are preserved while ensuring the output meets strict archival compliance standards required by government agencies, legal firms, and academic institutions.

Frequently Asked Questions

What is the difference between PDF/A-1b, PDF/A-2b, and PDF/A-3b?

PDF/A-1b provides basic visual preservation. PDF/A-2b adds support for JPEG2000 compression, transparency, and layers. PDF/A-3b allows embedding of any file type (such as spreadsheets or XML) as attachments within the PDF.

Will my document look the same after conversion?

Yes. The conversion process preserves the visual appearance of your document, including fonts, images, and layout. All required resources are embedded to ensure consistent rendering.

Is this tool free?

Yes, this PDF to PDF/A converter is completely free to use with no hidden fees, subscriptions, or watermarks on your converted documents.

Is my data secure?

Absolutely. Your files are processed securely and automatically deleted after conversion. We do not store, share, or access your document content.

Which PDF/A level should I choose?

For most archival purposes, PDF/A-1b is sufficient. Choose PDF/A-2b if your document uses transparency or advanced compression. Use PDF/A-3b if you need to embed additional files within the PDF.

Can I convert password-protected PDFs to PDF/A?

You will need to remove password protection from the PDF before converting it to PDF/A format, as the archival standard does not support encryption.

Tips & Best Practices

Choose the right level: Use PDF/A-1b for maximum compatibility, PDF/A-2b for modern features, and PDF/A-3b when you need to attach supplementary files.
Verify fonts before converting: Documents with unusual or custom fonts may require font substitution during conversion. Review the output to confirm accuracy.
Remove encryption first: PDF/A does not support password protection or encryption. Unlock your PDF before converting to archival format.
Check file size: Font embedding increases file size. For large documents, consider PDF/A-2b which supports more efficient compression methods.
Test with your archive system: After conversion, verify that your PDF/A file is accepted by your organization's document management or archival system.
Keep the original: Always retain your original PDF alongside the PDF/A version in case you need to make future edits to the document.
