Why archive as PDF if I have the original Office files?

Two reasons. First, file formats change — what opens cleanly in 2026 Office may not in 2036. PDFs are extraordinarily stable. Second, PDFs render identically everywhere — useful when you need to share evidence of past work with a university or employer.

Doesn't PDF lose editability?

Yes — that's the point. Archive PDFs alongside the originals, not instead of them. Keep the .docx for future editing; keep the PDF as the authoritative record of what the document looked like when you exported it.

How do I bulk-convert a folder?

On Mac: Automator → New Quick Action → Convert Office to PDF. On Windows: a PowerShell script using the Word COM object, or the free SmallPDF / iLovePDF tools (small batches). For large batches, LibreOffice has a headless --convert-to pdf command that handles hundreds of files in one go.

File types · PDF for archive

PDF as the archive layer.

Keep the originals. Then PDF a copy alongside them, so the authoritative record survives the next decade of format changes.

Why PDF

Renders identically on every device.
Doesn't need any particular app to open.
Format has been stable for 30 years; expected to continue.
Good for sharing with universities, employers, exam appeals.
Searchable text means you can find content years later.

Per-file conversion (small batches)

Open the file in its native app (Word / Excel / PowerPoint) and use File > Save As > PDF. Works on every platform. Word Online and Google Docs have the same option. Fine for one document at a time.

Bulk conversion (entire folders)

On Mac: open Automator, create a new Quick Action, drag in the Convert Office Documents to PDF action. Save as a service, then right-click a folder in Finder and run it.

On Windows: install LibreOffice (free), then run from PowerShell: soffice --headless --convert-to pdf *.docx. Repeat for .xlsx and .pptx.

Cross-platform: LibreOffice's headless mode works the same way on Linux, Mac and Windows.

Folder structure recommendation

Inside your school archive folder, keep two parallel trees:/originals and /pdf. Originals are the .docx / .xlsx / .pptx; PDFs are the bulk-converted archive copies. Future-you will thank you.
