About Converting PDF to PDF/A
PDF is the universal fixed-layout document format. It freezes fonts, images and layout so a file looks identical on every device, which is why it is the standard for contracts, invoices and reports. When you need to move away from PDF, the usual reason is simple: not easily editable.
Converting your PDF document to PDF/A solves that. PDF/A is an ISO-standardized version of PDF designed for long-term archiving. It embeds all fonts and forbids features that could stop the file rendering identically decades from now. In practice you gain guaranteed long-term reproducibility and self-contained with embedded fonts. PrivConvert runs the whole PDF-to-PDF/A conversion in server memory and deletes your file the instant the PDF/A is ready — nothing is stored, logged or reused.
