Why Convert to PDF/A?
The short version: PDF is optimized for sharing and archiving a fixed, print-ready document, PDF/A is optimized for long-term digital archiving that meets legal/regulatory retention standards, and this converter exists for the moment those two needs don't line up.
PDF/A was built around long-term digital archiving that meets legal/regulatory retention standards, which is precisely the gap PDF leaves open, since it's designed around sharing and archiving a fixed, print-ready document instead.
PDF/A is the ISO-standardized archival variant of PDF, built around long-term digital archiving that meets legal/regulatory retention standards. Converting from PDF — built around sharing and archiving a fixed, print-ready document instead — closes that gap.

Frequently Asked Questions
What happens to features specific to PDF that PDFA doesn't have? ▼
PDF's real strength — preserves an exact page layout regardless of viewing platform — has no equivalent once converted, since PDF/A's constraint is: more restrictive than regular PDF (no external references, embedded fonts required).
Is there a file size limit for this conversion? ▼
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
What software works with the converted PDFA file? ▼
PDF/A is used by archival and records-management systems. If you were working with Adobe Acrobat and virtually every PDF viewer (which produces PDF), this conversion is the direct bridge between the two.
How long does the conversion take? ▼
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
Do I need Adobe Acrobat and virtually every PDF viewer installed to convert my file? ▼
No — the conversion happens entirely on our servers. You don't need Adobe Acrobat and virtually every PDF viewer, and you don't need archival and records-management systems either unless you plan to open or edit the PDF/A result afterward.
