Word to PDF

Converting a Word document to PDF is one of the most common things people need to do with a file. A PDF looks the same on every device, cannot be accidentally edited, and is the expected format for sending a CV, submitting an assignment, sharing a contract or printing a report. Word documents, by contrast, can shift their layout depending on the version of Word, the fonts installed and the operating system — turning them into a PDF freezes the document exactly as you intended.

ColaPDF converts your .docx file to PDF entirely inside your browser. The document is rendered with its headings, fonts, lists, tables, colours and page breaks preserved, and then captured into a clean PDF — all without uploading anything. That makes it safe for confidential material like contracts, financial documents and personal letters, because your file never touches a server.

How it works

1. Upload your Word document (.docx) using the drop zone or click to browse
2. Choose the page size (A4, Letter or Legal) and the output quality
3. Click "Convert to PDF" — your document is rendered and converted in your browser
4. Download your PDF instantly — your file is never uploaded

Tips

• Save your document as .docx in Word (or export from Google Docs as .docx) before converting — the older .doc format is not supported.
• Choose "High" quality for documents you intend to print; "Normal" is smaller and perfect for sharing on screen.
• If your document relies on an unusual font, embed it or stick to common fonts so the layout matches what you see in Word.
• Very complex layouts — heavy multi-column designs or intricate tables — may shift slightly; check the result and adjust spacing in Word if needed.

Frequently asked questions

Are my files uploaded to a server?

No. The entire conversion happens locally in your browser using your device. Your Word file never leaves your computer.

Which file formats are supported?

Modern Word documents in .docx format. Older .doc files are not supported — open them in Word and save as .docx first.

Will my formatting be preserved?

Yes. The converter preserves headings, bold, italics, underline, lists, tables, colours and page breaks. Very complex layouts may differ slightly from Word.

Does it keep my fonts?

Common fonts are preserved. If your document uses an unusual font that is not available in the browser, a close substitute is used.

Is there a file size limit?

Because conversion runs in your browser, the limit depends on your device memory. Most everyday documents convert in a few seconds.
