DOCX to PDF — The final-artefact conversion — freeze the layout
DOCX → PDF is the "we're done editing, ship it" conversion. Contracts, invoices, resumes, cover letters, academic papers, and any deliverable that must render identically across recipients. Also required for portal uploads that specify PDF (most Indian government forms, bank KYC document uploads, university admissions, IRS / tax filings). Preserves fonts even when the recipient doesn't have them installed.
