Future-proof your files. Our PDF to PDF/A converter transforms standard documents into the ISO-standard format designed for long-term archiving and preservation.
What is PDF/A?
PDF/A (Portable Document Format Archive) is a specialized version of PDF. It restricts features that are ill-suited for long-term preservation, such as encryption and audio/video content, ensuring that the document will look exactly the same when opened 10, 20, or 50 years from now.
How it Works
Our tool scans your PDF and flags content that isn't archive-friendly. It embeds metadata tags that identify the file as PDF/A compliant, sets the creation date, and ensures the structure meets archival requirements.
How to Create PDF/A Files
- Upload: Choose any standard PDF document.
- Convert: The system automatically processes the file tags.
- Download: Save your newly archived-ready document.

Frequently Asked Questions
Can I edit a PDF/A file?
It is not recommended. Editing breaks the "preservation" seal. If you need to edit, convert it back to standard PDF first.
Why did my file size increase?
PDF/A often requires fonts to be embedded, which can add to the file size.
Can I convert it back?
Yes! Use our companion tool "PDF/A to PDF" to remove the restrictions.
Next Steps
Need to change it back? PDF/A to PDF reverses this process. Compress PDF is useful if embedding fonts made it too big.
