How to Convert Word to PDF on Mobile Devices

Mobile devices are increasingly used for professional work, with many users managing business workflows, reviewing materials, and signing contracts directly from their smartphones. When you receive a Word document `.docx` on your phone, you may need to convert it to a PDF before sending it back.

Fortunately, you don't need to install paid third-party apps to export PDFs on the go. This guide explains how to convert Word documents to PDF on both Apple iOS (iPhone/iPad) and Google Android devices using built-in system tools and free online converters.

Method 1: Use Our Free Online Converter (iOS & Android)

The easiest method that works on all smartphones is using a web-based converter like our free DOCX to PDF Converter. It runs entirely in your mobile browser, saving you from downloading extra apps.

1. Open **Safari** (on iOS) or **Chrome** (on Android) and go to our site.
2. Tap the **Select Word File** button in the upload box.
3. Select the `.docx` document from your phone's storage.
4. Tap **Convert to PDF**.
5. Once the conversion is complete, tap the green **Download PDF** button to save the file.

Apple iOS devices have a built-in PDF creator hidden inside the system share sheet:

Using the Files App or Mail

2. Tap the **Share** button (the icon showing a box with an arrow pointing up).
3. Select **Print** from the share menu options.
4. On the print preview screen, perform a pinch-out gesture on the document preview image. This action opens the file in iOS's full-screen PDF viewer.
