Why convert DOCX to PDF in the first place?
DOCX is the working format. PDF is the delivery format. When you send a contract, a proposal, a job offer letter, a tax form or an internal report as DOCX, the recipient can accidentally edit it, fonts can render differently on their machine, and the layout can shift. PDF freezes everything: the exact font you used, the exact layout, the exact page break, the exact watermark.
For confidential documents — NDAs, M&A drafts, employment contracts, signed proposals — there’s a second concern: the file should not be uploaded to a third-party server during conversion. That’s where the offline desktop path matters.
Three ways to convert DOCX to PDF on Windows
You have three real options on Windows. Each has trade-offs.
1. Microsoft Word: Save as PDF
If you have Microsoft 365 or Office 2019+, Word can save directly to PDF: File → Save As → choose PDF. Pros: free if you already pay for Office, preserves layout perfectly, supports document properties like outline / bookmarks. Cons: handles one file at a time (no batch), no password option in the basic flow, requires Word to be installed and licensed.
2. Windows Print to PDF
Windows 10 and 11 ship with a virtual “Microsoft Print to PDF” printer. Open the DOCX in Word or any other reader, hit Ctrl+P, pick the PDF printer. Pros: works without any extra install. Cons: rasterizes some content (text becomes images in places), strips bookmarks and outline, no batch, layout can drift on complex documents.
3. File Converter Pro (offline desktop app)
An offline Windows app that handles DOCX → PDF natively, including batch folders, PDF/A archival mode, font embedding, and AES-256 password protection. No upload, no watermark, no daily cap. €6.49 one-time on the Microsoft Store with a free trial.
Step-by-step: File Converter Pro
- Install from the Microsoft Store. Search for File Converter Pro in the Store and install. The free trial converts DOCX to PDF without watermarks.
- Drag your DOCX into the app. Drop a single file, multi-select, or a whole folder of contracts. Embedded images, tables, headers, footers and footnotes are all handled.
- Pick PDF settings. Choose PDF as the output. For a one-off shared file, defaults are fine. For archival, toggle PDF/A and embed all fonts. For confidential delivery, set an open-password (AES-256). Page size defaults to the DOCX setting (A4 or Letter).
- Click Convert. Files are processed locally on your CPU — never uploaded. The output PDFs are saved next to the originals or in a folder you specify. A 100-page contract typically converts in under 5 seconds.
What File Converter Pro adds over Word and Print-to-PDF
- Batch conversion. Drop a folder of HR templates, expense reports or signed contracts and process them all in one queue.
- PDF/A archival mode. Long-term-readable PDFs with embedded fonts and standardized color profiles. Required by some legal and government archive systems.
- AES-256 password protection. Open-password to require a password to view; editing-password to lock down further changes.
- No Word required. Useful when you receive a DOCX but don’t have Office installed (and don’t want to install LibreOffice for one job).
- Fully offline. Files never leave your computer — required for confidential contracts, salary letters, M&A documents.
Common DOCX to PDF issues and fixes
- Fonts look wrong in the PDF. Toggle “embed all fonts” in the output panel. Without it, viewers without the font installed substitute a default.
- Page breaks shift. Open the DOCX in Word once, save, then convert. Some DOCX files written by older tools have inconsistent style metadata that resolves on a Word save pass.
- Tables exceed page width. Set the DOCX page size to match the desired PDF page size before conversion (A4 vs Letter).
- Watermark or DRAFT label missing. Watermarks set as Word page-background images are preserved; ones added by an Office add-in may not transfer. Re-apply the watermark in the DOCX before conversion.

FAQ
Will DOCX to PDF preserve fonts and layout?
Yes. The conversion embeds the fonts referenced in the DOCX and preserves the page layout, headers, footers, and image positions. PDF/A mode embeds every font as a subset for long-term archival readability.
What is the difference between Save-as-PDF in Word and File Converter Pro?
Word’s built-in Save-as-PDF is good for one file at a time. File Converter Pro adds batch conversion of whole folders, password protection with AES-256, and optional PDF/A archival mode — and runs without Word installed.
Can I password-protect the output PDF?
Yes. Set an open-password (required to view the file) and an editing-password (required to modify) using AES-256 encryption. Both are configured in the output panel.
Is DOCX to PDF conversion offline?
Yes. Files never leave your computer — useful for contracts, proposals, NDAs and HR documents you can’t upload to a third-party converter.
