What is Office to PDF?
Word documents, Excel sheets and PowerPoint decks look different on every computer — fonts shift, layouts move, and the slide that looked perfect on your screen breaks on someone else’s. Converting to PDF fixes that: a PDF looks identical everywhere. Office to PDF turns your Office files into clean, fixed-layout PDFs that open the same on any device.
The conversion runs in your browser, so your document is not uploaded. You select the Office file, the tool produces a PDF, and you download it ready to share or print. It is the reliable way to send a document and know the recipient sees exactly what you intended.
Key features
Locks the layout
A PDF preserves fonts, spacing and formatting exactly, so a document or slide deck looks the same on every device — no shifted layouts or substituted fonts on the recipient’s end.
Universally openable
Not everyone has Word, Excel or PowerPoint, but everyone can open a PDF. Converting first means your file opens for any recipient, on any device, with no compatibility excuses.
Print- and share-ready
PDFs print consistently and are the expected format for formal documents, applications and submissions, so converting makes your file ready to send or print with confidence.
Private conversion
The file is converted on your device, so a confidential document becomes a PDF without being uploaded to a server.

- Check fonts and page breaks in the source document before converting so the PDF captures the layout you want.
- For a CV or application, always send the PDF rather than the editable file to protect your formatting.
