Convert Word to PDF offline.

CometPDF converts DOC, DOCX, and RTF documents to PDF on Windows. When Microsoft Word is installed, it uses Word's native export path for print-like layout, page breaks, images, headers, footers, fonts, and formatting. It is designed for everyday documents that need to become clean PDFs without being uploaded to a browser-based converter.

This is not an online converter. CometPDF is a Windows desktop app that converts Word files locally on your computer.

Download Installer

How it works

Install CometPDF for Windows.
Drag a Word document into the app or right-click it in Windows Explorer.
The PDF is created locally, usually next to the original file.

For the most accurate Word to PDF conversion, CometPDF uses Microsoft Word when it is installed on the computer. This gives the closest result to using Word's own Save as PDF or export feature, while keeping the process simple for non-technical users.

Why use an offline Word to PDF converter?

Many Word documents contain sensitive information: contracts, quotes, client proposals, internal notes, policies, HR documents, invoices, and legal drafts. Uploading these files to an online converter means sending your documents to a third-party server, even if only for a short time. That can be uncomfortable or unacceptable for offices, freelancers, accountants, lawyers, schools, and anyone working with confidential material.

CometPDF converts DOC, DOCX, and RTF files entirely on your Windows computer. Nothing leaves your machine during conversion. This matters for anyone working inside a restricted network, handling client documents, or simply preferring to keep files local. You install the app once, add your Word files, and create PDFs without account signups, browser uploads, or server-side file limits.

FAQ

Does CometPDF upload my Word document?

No. The conversion happens entirely on your Windows computer. CometPDF does not connect to the internet during conversion, and your Word files stay local at all times.

Do I need Microsoft Word installed?

Microsoft Word gives the best results. When Word is installed, CometPDF uses Word's native PDF export, which preserves page breaks, images, headers, footers, fonts, and layout as closely as possible.

Does it work on Windows 10 and Windows 11?

Yes. CometPDF runs on Windows 10 and Windows 11. The installer includes the desktop application and does not require users to upload files through a browser.

Can I convert multiple Word files at once?

Yes. Add as many DOC, DOCX, or RTF files as needed and convert them in one batch. You can also enable the merge option to combine all resulting PDFs into one file.

Is CometPDF free?

Yes, version 1.1.0 is free. A Pro version with additional features like OCR, compression, watch folders, and PDF page tools is planned for a future release.
