The basic steps for attaching a Word file

To attach a Word document to an email, you open your email program, start a new message, and use the attachment button to browse your computer for the file. The attachment button looks different depending on which email service you use — it might be a paperclip, a plus sign, or the word "Attach" — but every email program has one in roughly the same place on the compose screen.

The process takes about 30 seconds once you know where to look. After you attach the file, it stays attached even if you close and reopen the draft, so you can finish writing your message and send it whenever you're ready.

Key Takeaways

  • The attachment button is usually near the bottom of the compose window and looks like a paperclip, plus sign, or the word "Attach".
  • You can attach multiple Word documents at once by holding Ctrl (Windows) or Command (Mac) while clicking the files you want.
  • Most email services limit file size to 20 to 25 MB, so very large documents with many images may need to be compressed or sent through a file-sharing service instead.
  • Once you attach a file, it stays attached even if you navigate away from the message, so you can finish writing before sending.

How to attach in Gmail

Open Gmail and click the "Compose" button to start a new email. In the compose window that appears, look for the paperclip icon near the bottom left of the message box. Click the paperclip, and a file browser window opens on your computer.

Navigate to the folder where your Word document is saved, click the file to select it, and then click "Open" at the bottom right of the browser window. The file name appears below the subject line, and you can now finish typing your message and send it. If you need to attach more than one file, click the paperclip again and repeat the process.

How to attach in Outlook

Open Outlook and click "New Email" or "New Message" depending on your version. In the compose window, look for the "Attach" button in the toolbar at the top — it usually shows a paperclip icon. Click it, and your file browser opens.

Find your Word document, select it, and click "Insert". The file appears in the attachment area, usually shown as a small box with the file name and a paperclip icon. You can attach multiple files by clicking the Attach button again for each one. When you're done, type your message and click "Send".

How to attach in Yahoo Mail

Log into Yahoo Mail and click "Compose" to open a new message. Look for the paperclip icon in the toolbar — it's usually in the row of buttons below the subject line. Click the paperclip, and a file browser window appears.

Browse to your Word document, select it, and click "Open". The file name shows up in the attachment area below the message body. Yahoo Mail lets you attach up to 25 MB total per message, so you can usually add several documents at once. Finish your message and click "Send" when ready.

What to do if the file is too large

Most email services limit attachments to 20 to 25 MB per message. If your Word document is larger than this — usually because it contains many high-resolution images or embedded videos — you have two options: compress the file or use a file-sharing service.

To compress a Word file on Windows, right-click the document, select "Send to", and then "Compressed (zipped) folder". On Mac, right-click the file and select "Compress". The compressed version is usually 30 to 50 percent smaller. If compression still doesn't bring it under the limit, upload the file to Google Drive, OneDrive, or Dropbox instead, and send your recipient a link to download it from there.

Common mistakes to avoid

The most common mistake is forgetting to attach the file entirely. If you mention the document in your message but don't actually attach it, most email programs will warn you before sending — look for a popup that says something like "You mentioned an attachment but didn't attach a file." Take a moment to attach it before clicking send again.

Another mistake is attaching the wrong version of a file. If you have multiple versions of a document saved — like "Resume_Final.docx" and "Resume_Final_FINAL.docx" — double-check that you're sending the one you actually want. A third common problem is not waiting for the upload to finish before closing your email. If you click send while the file is still uploading, the message may go out without the attachment. Wait until you see the file name appear in the attachment area before sending.

Attaching files from cloud storage

If your Word document is stored in Google Drive, OneDrive, or Dropbox instead of your computer's hard drive, you can still attach it directly from most email programs. In Gmail, click the paperclip icon and look for a "Google Drive" tab or option. In Outlook, click "Attach" and select "Browse Cloud Locations" or "OneDrive". This method is faster than downloading the file to your computer first and then attaching it.

When you attach from cloud storage, the recipient gets the actual file, not just a link. This works the same way as attaching from your computer, and the file size limits still apply. If you want to send a link instead so the recipient can view or edit the document online, most email programs also have an option to "Insert Link" rather than attach the file itself.

Frequently Asked Questions

Can I attach a Word document to an email on my phone?

Yes. Open your email app, start a new message, and look for a plus sign, paperclip, or attachment icon — usually at the bottom of the compose screen. Tap it, browse to your document, and select it. The process is the same on iPhone and Android, though the exact location of the button varies by app.

What if the recipient can't open my Word document?

Ask what version of Word or what program they use to open documents. If they don't have Microsoft Word, they can open .docx files in Google Docs, LibreOffice, or online through Office.com. If they're using an older version of Word, save your document as .doc instead of .docx before attaching. You can do this by clicking "File", then "Save As", and choosing "Word 97-2003 Document" from the format dropdown.

Can I attach a Word document and a PDF at the same time?

Yes. Click the attachment button once, select your Word document, and then click the attachment button again and select your PDF. Most email services let you attach multiple files of different types in a single message, as long as the total size stays under the limit.

Does the recipient need Word installed to read my attachment?

No. Word documents can be opened in any web browser through Office.com, or in free programs like Google Docs and LibreOffice. The recipient doesn't need to own Microsoft Word to read or edit your document, though they may see minor formatting differences depending on what program they use.

What happens if I attach a file and then edit it on my computer?

The email contains the version of the file that was attached at the time you sent it. If you make changes to the document after sending, those changes won't appear in the email attachment. The recipient will have the older version unless you send a new email with the updated file attached.
