If a document must still open correctly in 10–20 years — legal records, theses, government filings — a regular PDF isn’t guaranteed. PDF/A is the ISO-standardized flavor built for archiving.
What makes PDF/A different
- Fonts are embedded (no “font missing” a decade later).
- No external dependencies (no linked content that can rot).
- No encryption or JavaScript — self-contained and stable.
That self-containment is exactly why some courts, libraries, and archives require PDF/A.
How to convert to PDF/A step by step
- Open PDF to PDF/A and select the file.
- Convert — fonts get embedded and disallowed features removed.
- Download the PDF/A-compliant file.
Tips
- Convert the final version. PDF/A is for archiving, not active editing — finish edits first.
- Scanned archives: run OCR first so the archive is searchable, then convert.
- Keep your working copy separately for future changes.
