PDF vs Word Doc: When to Use Which (And Why It Still Comes Up)

PDF for almost everything, unless the employer explicitly asks for Word. Here's why: Word documents render differently on different systems — fonts substitute, spacing shifts, formatting breaks when opened in an older version of Office or LibreOffice. Your carefully formatted resume can look like a disaster by the time it reaches the hiring manager. PDF locks the layout. The one exception is ATS (Applicant Tracking Systems) — some older ATS software parses Word docs more reliably than PDFs. If you're applying through an online portal that processes your resume, Word may parse better. When in doubt and when you have the choice, send PDF.

Yes, but with caveats. PDFs weren't designed for editing — they were designed for precise layout that looks the same everywhere. Editing a PDF in Adobe Acrobat Pro is possible but awkward, especially if you're doing more than fixing a typo. The text reflow is clunky, adding pages is painful, and fonts may not match exactly. For anything beyond minor corrections, the right approach is editing the source document (Word, InDesign, Google Docs) and re-exporting to PDF. If you only have the PDF and not the source, tools like PDF-to-Word converters can get you back to editable, but expect formatting cleanup work.

Two reasons: layout fidelity and archival stability. A contract, court filing, or government form needs to look identical when printed, regardless of who opens it, on what software, five years from now. PDFs guarantee that. Word documents don't — fonts go missing, features get deprecated, compatibility breaks. PDF/A is a specific archival variant of PDF designed for long-term preservation, with all fonts and color profiles embedded and no external dependencies. It's the standard for legal and government archival specifically because of this reliability.
