How to Convert Word to PDF on iPhone and iPad
The fastest route needs no app at all: save the .docx into the Files app, press and hold it, scroll to Quick Actions, and tap Create PDF. The PDF appears in the same folder a second later, with the same name and a .pdf extension. If Create PDF isn't there, or the result doesn't look right, there are three other ways to do it on an iPhone or iPad — including one that works with the phone in Airplane Mode.
Method 1: Files app, Create PDF
This is built into iOS, costs nothing, and takes about fifteen seconds. The only prerequisite is getting the .docx into the Files app first.
- Save the attachment. In Mail, tap the attachment to open its preview, tap the Share icon (the square with an arrow pointing up), then Save to Files. Choose a folder you'll remember — On My iPhone > Downloads or iCloud Drive. Gmail, Outlook and WhatsApp all offer the same Save to Files step from their share sheets.
- Open the Files app and go to that folder.
- Press and hold the file until the menu appears, then scroll down that menu to Quick Actions and tap Create PDF.
There is no progress bar and no confirmation dialog — the PDF simply shows up next to the original, named identically apart from the extension. Press and hold it and choose Rename if you want it called something else before you send it.
One thing worth knowing before you trust the output: Create PDF renders the document through Quick Look, Apple's own preview engine, not through Word. More on what that means below.
Method 2: the Print trick, when Create PDF isn't offered
Sometimes Create PDF is missing from the Quick Actions menu — this happens with some file types, and with files stored in a third-party provider surfaced inside Files rather than on the device. It also doesn't help when the document is stuck inside an app that won't hand it over, like a preview in an email client.
In those cases, use the print sheet. You do not need a printer, and you do not need to select one.
- Open the document, tap Share, then Print.
- On the Printer Options screen, the page thumbnails sit at the bottom. Put two fingers on the first thumbnail and spread them apart.
- The preview opens full screen. That full-screen view is already a PDF.
- Tap the Share icon in the corner, then Save to Files — or send it straight to Mail or WhatsApp from the same sheet.
If you see a share icon on the print screen itself, use that and skip the pinch. The gesture is only needed when iOS doesn't give you a share button up front.
Method 3: Safari, with nothing installed and nothing uploaded
Our Word to PDF converter runs in mobile Safari. Tap the file box, pick the .docx from Files or iCloud Drive, and the PDF is built by JavaScript running inside the browser tab. Nothing is sent anywhere — there is no server behind it. Load the page, switch the phone to Airplane Mode, and the conversion still completes. That is the point of it, and it's easy to check.
Mainstream converters upload the file to their own servers to do this — what that actually means is worth two minutes if the document is sensitive.
The browser converter handles headings, bold, italic, underline, text colors, indents, bullet and numbered lists with correct restarts, and tables with borders and merged cells. Embedded JPG and PNG images are copied into the PDF byte-for-byte rather than re-encoded, so photos don't soften. Hyperlinks become real, tappable link annotations. Page size and margins are read from the document itself.
What it will not do: headers and footers, footnotes, floating text boxes, shapes, charts, or multi-column layouts. It typesets in DejaVu Sans, so your Calibri or Aptos gets substituted. It covers Latin, Cyrillic and Greek — Chinese, Japanese, Korean, Thai and Devanagari raise an explicit error rather than printing rows of empty boxes.
Method 4: the free app, if this isn't a one-off
Installing something for a single conversion is a waste of time — Method 1 is faster. The case for the app is repetition, offline use, and the share sheet.
Our Word to PDF Converter: Docx app is free, runs on iPhone and iPad with iOS 15.1 or later, and holds 4.4 stars from 24 ratings. It converts entirely on the device, so it works on a plane or in a basement with no signal, and it adds no watermark. Because it appears in the iOS share sheet, you can go from an email attachment to a finished PDF without ever opening the Files app: tap the attachment, tap Share, choose the app, and the PDF comes back out. There's an Android version too.
What each method actually does to your formatting
None of these four is a pixel-perfect reproduction of Word, and it's worth knowing how each one goes wrong.
- Files' Create PDF renders through Quick Look. Quick Look reads .docx well, but it is a viewer, not Word — it makes its own font-substitution and line-breaking decisions when your typeface isn't installed on the phone. The result can differ from Word's own export: different page breaks, occasionally an extra page at the end. Open the PDF and check the page count before you send it.
- The Print trick captures whatever the previewing app has already drawn, then applies printer margins. An edge-to-edge design can end up slightly scaled or trimmed.
- The browser converter reads the document's XML directly, which is why links stay clickable and images stay sharp — but it substitutes fonts and drops headers, footers and footnotes.
- The Microsoft Word app is the only faithful option, because it's the same engine that made the file: three-dot menu > Export > PDF > choose a location > Export. (There's also three-dot > Send a Copy > Share as PDF, if you're sending it immediately.) The app is a free download, though on larger iPads you may hit its subscription gate.
The rule of thumb: if the exact typeface is part of the document — a branded proposal, a designed CV — export from Word itself. If the content is what matters, any of the four is fine. If your fonts came out wrong, why fonts change during conversion explains what's happening.
If the attachment is a .doc, not a .docx
Check the file name. A .doc file is the pre-2007 binary format, and it is a genuinely different thing from .docx, not just an older version of it.
Our browser converter detects it and tells you plainly to re-save the file, rather than producing a broken PDF and letting you find out later. Files' Create PDF is inconsistent with .doc: if Quick Look shows you a readable preview, Create PDF will usually work; if you get "No preview available", it won't.
The reliable fix on a phone is to open it in the Microsoft Word app, which reads .doc fine, and export from there with three-dot > Export > PDF. On a computer, uploading it to Google Drive and using File > Download > PDF Document in Google Docs does the same job. More detail in when a .doc file won't convert.
Sending the finished PDF without it being re-compressed
PDFs survive email and messaging intact — as long as you send them as files rather than as pictures.
Mail: tap in the message body, tap the attachment button, and pick the PDF from Files. It goes as-is. If iOS offers Mail Drop because the file is large, understand what that does: the recipient gets a download link that expires, not an attachment. Some corporate mail systems strip those.
WhatsApp: in the chat, tap the attachment button and choose Document, then browse to the PDF. Do not go through the photo picker — WhatsApp compresses images and video aggressively, and a page sent as an image comes out soft and unreadable at small text sizes. Documents pass through untouched. The full walkthrough is in sending a Word document as a PDF on WhatsApp.
If the PDF is simply too large for the mail server to accept, why Word-to-PDF files get big covers what's usually responsible — almost always full-resolution photos pasted into the document.
