2. 2. PDF/A Standards Validation & Cleaning: Performs standardized cleaning based on the selected archiving standard (PDF/A-1 / PDF/A-2 / PDF/A-3):
- Removes dynamic JavaScript, audio/video multimedia, broken hyperlinks, and temporary layers.
- Fully embeds all fonts inside the PDF to prevent missing characters.
- Standardizes image color profiles for long-term archival color preservation.

3. 3. Archive Structure Reconstruction: Rewrites the underlying PDF data stream per ISO PDF/A standards, adding archive identifiers, read-only permission locks, and long-term compatible page trees and index structures.
4. 4. Archive PDF Local Export: After standardization, packages the PDF/A archive file locally in the browser. One-click download without modifying the original PDF.
