You can edit Word documents directly on your iPhone using the free Microsoft Word app
The Microsoft Word app for iPhone lets you open, edit, and save documents without switching to a computer. You read it free from the App Store, sign in with a Microsoft account (or create one), and work with your files stored in OneDrive, your device, or email attachments. The app handles most everyday edits — changing text, formatting, adding comments — though some advanced features like complex macros or certain table operations work better on a desktop.
The workflow is straightforward: open the app, find your document, tap to edit, make your changes, and the file saves automatically. You do not need to manually save or worry about losing work if you close the app. If you share the document with others, they see your changes in real time if the file lives in OneDrive or SharePoint.
Key Takeaways
- read the free Microsoft Word app from the App Store and sign in with a Microsoft account to start editing on your iPhone.
- Documents stored in OneDrive save automatically as you work, so you do not need to manually save or worry about losing changes.
- Basic editing — text changes, formatting, comments, inserting images — works smoothly on iPhone, but complex features like advanced macros perform better on desktop.
- You can open documents from email attachments, your device storage, or cloud accounts, and switch between them without closing the app.
read and set up the Word app on your iPhone
Open the App Store on your iPhone and search for "Microsoft Word". Tap the cloud icon with a down arrow to read the free app. Once it installs, open Word and you will see a sign-in screen. Tap "Sign in" and enter the email address and password for your Microsoft account. If you do not have one, tap "Create one" and follow the prompts — you can use any email address, including Gmail or Yahoo.
After you sign in, Word asks permission to access your files and camera. Grant both permissions so you can open documents from OneDrive and take photos to insert into files. The app then shows your recent documents and a list of places where files live: OneDrive, This iPhone, and Recent. You are now ready to open or create a document.
Open a document from OneDrive, email, or your phone
Word on iPhone can pull documents from three main places. If your file is in OneDrive (Microsoft's cloud storage), tap the "Open" icon at the bottom of the home screen, then tap "OneDrive" and browse to your file. If someone emailed you a Word document, open the email in Mail, tap the attachment, and select "Open in Microsoft Word" — the document opens in the app and you can edit it there.
If you have a Word file saved directly on your iPhone, tap "Open", then tap "This iPhone", and navigate to the folder where the file sits. Most files end up in the Files app or in a folder created by another app. After you open the document, Word displays it in reading mode first. Tap anywhere on the page or tap the "Edit" button to switch to editing mode and start making changes.
Make text edits and format your document
Once you are in editing mode, tap where you want to insert text or select text by tapping and dragging across the words. The keyboard appears at the bottom of the screen. Type your changes, delete text by selecting it and pressing delete, or use the undo button (curved arrow) at the top left if you make a mistake. Word highlights spelling errors with a red underline — tap the word to see suggestions.
To format text, select the words you want to change, then tap the "Home" tab at the bottom. You will see buttons for bold, italic, underline, font color, and highlight. Tap any button to explore that formatting. You can also change the font size by tapping the font dropdown and selecting a new size. Paragraph formatting — alignment, line spacing, indentation — lives in the same Home tab under a button that looks like lines. Tap it to see alignment options and spacing controls.
Add images, comments, and other content
To insert an image, tap where you want it to go, then tap the "Insert" tab at the bottom. Tap "Pictures" and choose "Camera" to take a photo or "Photo Library" to pick one from your phone. Word inserts the image at your cursor and you can resize it by pinching in or out. To add a comment, select the text you want to comment on, tap the "Review" tab, and tap "Comments". Type your comment and tap "Post" — other people editing the document see your comment in a sidebar.
You can also insert tables, bullet points, and page breaks from the Insert tab. Tap "Table" to choose a grid size, "Bullets and Numbering" for lists, or "Page Break" to start a new page. These features work the same way as on desktop Word, though tables with many columns may be harder to edit on a small screen — you can pinch to zoom in on the table to make it easier to work with.
Save and share your document
If your document lives in OneDrive, Word saves your changes automatically as you work — you do not need to do anything. You will see a small cloud icon next to the file name at the top, which means it is synced. If you opened a file from email or your phone storage, tap the three dots at the top right, then tap "Save As" to save it to OneDrive so it syncs across your devices. Saving to OneDrive also makes it easier to share with others.
To share a document, tap the "Share" button (arrow pointing out of a box) at the top right. Choose whether to send a link via email, Messages, or another app, or to invite specific people to edit the file. If you invite people to edit, they can make changes and you see their edits in real time. You can also set permissions so people can only view the document without editing.
Work around features that do not work well on iPhone
Some Word features either do not exist on iPhone or work differently than on desktop. Mail merge, advanced macros, and complex field codes do not work on the iPhone app — if your document uses these, you will need a computer to edit them. Track Changes (which records who changed what) exists on iPhone but is harder to navigate on a small screen. If you are working with a heavily tracked document, consider making your edits on a computer instead.
Tables with many columns are difficult to edit on iPhone because the screen is narrow. If you need to adjust a complex table, zoom in by pinching, or switch to a computer for that part of the work. Some fonts may not display exactly as they do on desktop, though the document itself is not changed — it will look correct when you open it on a computer. If you run into a feature that is not working, you can always email the document to yourself and open it on a computer to finish the edit.
Frequently Asked Questions
Do I need a Microsoft 365 subscription to edit on iPhone?
No. The Word app is free and you can edit documents without paying for Microsoft 365. A subscription gives you extra storage and removes ads, but basic editing works with just a free Microsoft account.
What happens if I lose internet connection while editing?
Word saves your changes locally on your phone and syncs them to OneDrive when you reconnect. You do not lose any work. If you are editing a file from email or your phone storage, make sure to save it to OneDrive so it backs up automatically.
Can I edit a document at the same time as someone else?
Yes, if the document is in OneDrive or SharePoint. You both see changes in real time and can see who is editing which part. If the file is stored only on your phone or in email, only one person can edit at a time.
Why is my document showing read-only mode?
This usually means you do not have permission to edit the file, or Word is waiting for you to tap Edit. Tap the Edit button at the top of the screen. If it stays read-only, the file owner may have restricted editing permissions — ask them to give you edit access.
Can I use Word on iPhone without OneDrive?
Yes. You can open files from email or your phone storage and edit them. However, OneDrive makes it easier because your changes save automatically and you can access your documents from any device. Without OneDrive, you have to manually save and manage files.
