How to open docx file attachments on any computer or phone

On a Mac, you can open a .docx file with Apple Pages, which costs nothing and is often already installed: right-click the file and choose Open With › Pages. TextEdit opens it with basic formatting, Quick Look previews it when you press Space, and Publish Media Software opens it in Safari with every page laid out.

On Windows 11 without Word, open a .docx file in a browser with Publish Media Software, Word for the web or Google Docs, or install LibreOffice Writer or WPS Office. WordPad is no longer an option, because Microsoft removed it starting with Windows 11 version 24H2. Notepad shows only scrambled characters.

On an iPhone, you can tap a .docx file in Mail or the Files app to see a preview, or open it in Apple Pages, which is available at no cost from the App Store. The Google Docs app for iPhone also opens .docx files if you use Google Drive.

On Android, open a .docx file with the Google Docs app: tap the file in your Downloads folder or in Gmail and choose Google Docs. WPS Office also has an Android version with ads. For a page-accurate look at a designed document, use a computer or iPad browser with Publish Media Software.

.doc is the older binary Word format used by Word 97–2003, while .docx is the XML-based format Word has used by default since Word 2007. A .docx is a compressed ZIP package of XML files and an open ISO/IEC standard. Current versions of Word, Google Docs, LibreOffice Writer and Publish Media Software open both kinds.

Yes, you can open a .docx file without downloading software by using a browser-based tool such as Publish Media Software, Word for the web or Google Docs. Of those three, only PublishMedia works without a Microsoft or Google account, and viewing there costs nothing. On a Mac, Quick Look and TextEdit are already built in.

Microsoft Word is the default program for .docx files, because the format was created for Word 2007 and later. If Word isn’t installed, you can choose another app as the default: on Windows, right-click the file and pick Open with › Choose another app; on a Mac, use Get Info › Open with › Change All.

A .docx file shows strange symbols when it is opened in a plain-text program such as Notepad, because a .docx is really a compressed package of XML files. Open it in a word processor or a docx viewer instead. If a proper word processor also shows errors, the file may be damaged, so ask the sender for a fresh copy.

A password-protected .docx file opens in Microsoft Word once you enter the password. Publish Media Software cannot open password-protected files, and neither can Google Docs. If you don’t know the password, ask the person who sent the document for an unprotected copy rather than trying to break the protection.

A .docx file can carry harmful content, but a standard .docx cannot hold macros, a common way Word files spread malware; macro-enabled documents use the .docm extension instead. Open attachments only from people you know and were expecting. Publish Media Software never runs macros, even in .docm files.
