About Convert to PDF/A
Modufile's PDF/A Conversion tool transforms standard PDFs into archival-compliant PDF/A format — the ISO standard (ISO 19005) for long-term document preservation. PDF/A files embed all fonts, use standardized color spaces, and are fully self-contained, ensuring they render identically decades from now regardless of the software used to open them. The conversion is handled by the MuPDF engine running locally in your browser via WebAssembly. This format is required by many government agencies, courts, academic repositories, and corporate archival systems. Unlike server-based conversion tools, your documents never leave your device.
