Preserve more than a file extension
Archive-ready PDFs need more than a name that says PDF/A. A useful handoff file should be readable, searchable, navigable, structurally reviewable, and trustworthy enough for the retention or compliance process that receives it.
This workflow starts with the source condition. If the file is a scan, use pdf-denoise and pdf-deskew before adding searchability with pdf-ocr-text-layer. If the source of record is a DOCX, libreoffice-docx-to-pdf-a gives a direct export path that avoids unnecessary scan-style repair.
Separate conversion from acceptance
After the pages are usable, prepare the archival candidate with pdf-a-convert or the DOCX export path, then run pdf-a-validate. The validation report matters because archive acceptance depends on evidence, not just on the file name, embedded metadata, or a one-step conversion claim.
Finish with human-use and trust checks
Long-term storage also needs practical usability. pdf-accessibility-check and tagged-pdf-inspector expose whether the file carries useful structural signals, while pdf-outline-bookmarks helps reviewers navigate long records. Before final delivery, pdf-signature-verify confirms whether existing signatures still support the trust story or whether the file needs a new signing process.
