Converting a Word document to PDF on iPhone is something the Microsoft Word app and a few other tools handle directly — no computer required. Here's how to do it and what to expect from the output.
How to Convert Word to PDF in the Microsoft Word App
Open the Word document in the Microsoft Word app for iPhone. Tap the three-dot menu in the top-right corner and select Export. Choose PDF from the list of export formats. Word generates the PDF and gives you options to share it immediately via AirDrop, email, or save it to Files. The conversion is done on-device and typically takes a few seconds.
The Word app produces faithful PDF output — fonts, images, tables, and page layout are preserved accurately. This is generally the best method for .docx files because Word knows exactly how to render its own format.
Converting Word to PDF Using the Files App
If the Word document is saved in Files or iCloud Drive, you can create a PDF without opening the Word app at all. Tap and hold the .docx file in Files, then select Quick Actions > Create PDF. iOS converts the document using its built-in rendering engine and saves the PDF in the same folder.
This Quick Actions method is convenient but may not handle complex Word formatting as precisely as the Word app itself — documents with custom styles, tracked changes, or complex tables may look slightly different in the PDF output. For simple documents, the difference is usually unnoticeable.
Converting Word to PDF in Pages on iPhone
Apple's Pages app can open .docx files and export them as PDF. Open the document in Pages, tap the three-dot menu, select Export, and choose PDF. Pages offers image quality options before exporting — choose Better for most documents, or Best for those with high-resolution photos or detailed graphics.
Pages may reinterpret some Word-specific formatting — fonts not available on iOS, certain table styles, or Word-specific header and footer elements — but for most business documents, the output is clean and usable.
Converting Without Any Apps Using WukongPDF
If neither Word nor Pages is installed, WukongPDF's Word to PDF tool in Safari handles the conversion from the browser. Upload the .docx file, convert it, and download the PDF to Files. This is particularly useful for converting files received as email attachments when you just need a quick PDF without setting up any apps.
Sharing the PDF After Converting on iPhone
Once the PDF is in Files, tap and hold it to access the Share sheet. From there you can email it, send via Messages, share via AirDrop to a nearby device, or upload it to Google Drive, Dropbox, or any other cloud service connected to your iPhone.
If the PDF is larger than expected — common with documents containing embedded images — running it through WukongPDF's Word to PDF workflow in Safari and then applying compression brings the file size down before sharing. Most Word-derived PDFs compress well, especially those with office-quality rather than print-quality images.
