Here’s how to convert a DOCX file to PDF format using our online tool

How Does the Smallpdf Word to PDF Tool Work?


We actually automate the saving process that Microsoft Office uses to save to PDF. When you drag and drop your DOCX file, our digital “worker” carries out this task! Don’t worry, all uploaded files are deleted one hour after processing. If you want to share the output file with someone, you can share the file via email, or even create a downloadable URL on the result page. Otherwise, no one will ever have access to your document.

Can I Revert the Change?


Yes. You can use the PDF to Word tool to change the file back to its original formatting and file type. If you need to switch it back to a DOCX file from a PDF, it’s no problem at all.

Is the Tool Free?


Yes, it is! All of Smallpdf’s tools are free to use—up to two tasks a day. Besides converting DOCXs to PDFs, we can also save your files to JPEG, Excel, and PPT formats and convert older Word files, such as the legacy .doc format.

Plus, you can enhance your PDF files however you like. For example, you can delete pages, split up large documents, and combine them—sky’s the limit! If you work extensively with documents and need unlimited access, you can try Smallpdf Pro—there’s a 7-day free trial. You’ll also get access to Pro-exclusive perks, such as batch processing, file storage, and access to the offline Smallpdf Desktop App!

Is This Tool Safe?


File security is very important at Smallpdf. We take privacy and security very seriously, which is why millions of people count on our online service every day, for schoolwork, professional work, for everything!

All file transfers are fully encrypted. Our servers will also automatically detect and remove your files from our system after one hour. We only keep them online this long for you to have enough time to download them!

What Else Can I Do?


The PDF format is much more versatile when compared to other file formats such as .docx, vector graphics, or spreadsheets. PDFs are accepted by most operating systems and their content can’t be edited easily. Furthermore, they’re not dead ends. Whenever you receive a PDF, you can always convert it to a different file format or edit it using our suite of free PDF tools. Here’s a list of just some of the things you can do to enhance your PDF:

  • eSign - add an electronic signature to your PDFs
  • Protect - encrypt your files with a password
  • Edit - add text, images, or annotations

And much more, you’ll find all our tools on our homepage. You can also convert DOCX to PDF on your mobile using the Smallpdf Mobile App. With the mobile app, you’ll get access to your favorite PDF tools so you can get your work done from anywhere. Try it out!
