Converting a Word document to PDF on iPhone is something you can do natively without any apps — iOS includes built-in PDF export in several places. If you prefer a browser-based option or are working with a file format that Apple apps do not handle perfectly, there are online alternatives too.
All four methods below are free. Which one is best for you depends on where your Word file is stored and what tools are already on your iPhone.
Method 1 — Using the Microsoft Word app (most accurate)

- Open your .docx file in the Microsoft Word app (free to download, requires Microsoft account for editing).
- Tap the three-dot menu (···) in the top-right corner.
- Select 'Export' then 'PDF'.
- Choose where to save: Files, iCloud Drive, or share directly.
- The PDF is created instantly with all fonts, tables, and images preserved.
Method 2 — Using the iOS Files app (no Word app needed)
- Open the Files app and find your Word document.
- Long-press the file to bring up the context menu.
- Tap 'Quick Actions' then 'Create PDF'.
- The PDF is saved in the same folder as the original .docx file.
Method 3 — Using Apple Pages

- Open your Word document in Pages (if Pages is installed — it is free on all iPhones).
- Tap the three-dot menu → Export → PDF.
- Choose PDF quality and save to Files or share.
Method 4 — Use a free online converter (no app needed)
If you do not have the Word app installed and the Files app method is not giving you the right output, a browser-based converter handles .docx to PDF with excellent formatting fidelity.
- Open Safari on iPhone and go to pdftoolz.io/tools/word-to-pdf.
- Tap 'Choose File' and select your Word document from Files or iCloud.
- Tap 'Convert to PDF' and download the result.

Use pdftoolz.io/tools/pdf-to-word in Safari. Upload the PDF, convert, and download the .docx file. This requires an internet connection but no app installation.
QWhy does my Word to PDF conversion look different on iPhone?
If custom fonts used in the Word document are not installed on your iPhone, the iOS rendering engine substitutes them. Using the Microsoft Word app or an online converter that uses Microsoft's rendering engine avoids this issue.
