Why Standard PDFs Fail Archival Verification
A standard PDF can reference external fonts installed on your local computer, link to remote web assets, contain interactive JavaScript forms, and include password encryption.
If that file is opened 30 years from now on a different operating system where those fonts do not exist, the layout corrupts. PDF/A strictly forbids dynamic elements and mandates 100% font embedding and device-independent color spaces.
Conformance Levels: PDF/A-1b vs PDF/A-2b
For most legal and governmental filings, PDF/A-1b (Basic Visual Conformance) is sufficient to guarantee identical visual rendering.
If your document contains transparent layers or embedded attachments, PDF/A-2b or PDF/A-3 provides modern compression and layer support.
