Step-by-step instructions

Method 1: File → Export as PDF in Word for Mac
The best method if you have Word for Mac installed. Open your document in Word. Go to File → Save As → select PDF from the Format dropdown. Or: File → Export... → Create PDF/XPS (older Word versions use this interface). This uses Word's own PDF engine, which produces the most accurate layout conversion with all fonts embedded correctly.

Method 2: Print to PDF (works with any application)
Works even without Word installed — use TextEdit, Pages, or any app that opens DOCX. Open the document → File → Print (⌘+P) → in the Print dialog, click the PDF dropdown at the bottom left → Save as PDF. Choose location and filename → Save. This method uses macOS's built-in PDF engine (the same one that powers Preview). Quality is excellent for most documents.

Method 3: Open in Pages and export as PDF
Pages (free on all Macs via the App Store, included on new Macs) opens DOCX files and can export as PDF. Open the DOCX in Pages (it converts on open). Go to File → Export To → PDF. Select image quality (Best for more embedded images, Smaller for more compressed). Click Next → choose save location → Export. Note: Pages may reformat some Word-specific formatting elements.

Method 4: Quick Look + Export (macOS Sequoia only)
On macOS Sequoia and later: select the DOCX file in Finder → press Space to Quick Look → click the Share button → Print → Save as PDF. This works without opening any application.

Verify the PDF output
Open the resulting PDF in Preview to verify: all text is correct, images appear, and layout matches the original. Check page count. Open on a different device (iPhone, Windows PC) to confirm it renders identically — PDFs should look the same everywhere. If fonts appear wrong, try Method 1 (Word's own PDF export embeds fonts most reliably).
Why convert DOCX to PDF?
macOS has had built-in PDF generation since Mac OS X 10.0 (2001) — Apple's system-level print architecture is based on PDF internally, which is why every Mac application can 'print to PDF' without any additional software. This is fundamentally different from Windows, where PDF export was an add-on until relatively recently. The different methods produce slightly different PDFs: Word's PDF export embeds fonts and preserves Word-specific features like tracked changes and embedded metadata. Print to PDF uses the same CUPS-based print path as printing to a physical printer, then wraps the output in a PDF container. Pages export may reflow some complex Word formatting. For most documents, all three methods produce identical-looking output.
Your files never leave your device
FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.
