The fastest way depends on where your document lives

If your document is saved on your computer, right-click the file, select "Copy", then right-click in the same folder and select "Paste". Windows will create a file named "Copy of [original name]". On a Mac, right-click the file, select "Duplicate", and the copy appears when ready in the same folder.

If your document is in Microsoft Word Online or Google Docs, the process is different because the file lives in the cloud rather than on your hard drive. Both services let you duplicate without downloading anything first, which means the copy stays in your account and syncs across your devices automatically.

The method you choose affects where your data sits and who can see it — something worth thinking about if you came here from the privacy guide. A local copy on your computer stays on your computer. A cloud copy lives on Microsoft's or Google's servers, depending on which service you use.

Key Takeaways

  • On your computer, right-click the file and select Copy (Windows) or Duplicate (Mac) to create a copy in the same folder when ready.
  • In Microsoft Word Online, open the file, click File, then select "Save a Copy" to create a duplicate in your OneDrive without leaving the browser.
  • In Google Docs, click File, then "Make a copy" to duplicate the document in your Google Drive with a new name.
  • A copy stored locally on your computer never leaves your device; a copy in Word Online or Google Docs is stored on those companies' servers and synced to your other devices.

Duplicating a document saved on your computer

Open the folder where your Word document is stored. Right-click directly on the file name (not on the folder itself). A menu will appear with several options. Select "Copy".

Now right-click in an empty area of the same folder. Select "Paste". A new file will appear with the name "Copy of [original document name]". The copy is identical to the original — same formatting, same content, same file size. Both files are now on your computer, taking up storage space.

If you want to rename the copy when ready, right-click it and select "Rename", then type the new name. This is useful if you are working on versions of the same document and want to keep them straight.

Duplicating a document in Microsoft Word Online

Open the document in Word Online (the version you access through your web browser at office.com). Click the "File" menu in the top left corner. A sidebar will open on the left showing several options.

Look for "Save a Copy" in that menu. Click it. Word will create a duplicate of the document in your OneDrive account and give it a name like "[Original Name] - Copy". The new file opens automatically in a new tab so you can see it was created. Both the original and the copy now exist in your OneDrive, and both are synced to any device where you have OneDrive installed.

If you want to change the copy's name, click the file name at the top of the document and type a new one. The change saves automatically.

Duplicating a document in Google Docs

Open the document in Google Docs. Click the "File" menu at the top left. A dropdown menu will appear with several options.

Select "Make a copy". A dialog box will pop up asking what you want to name the copy. By default, Google suggests "[Original Name] - Copy". You can accept that name or type a different one. Click "Make a copy" in the dialog box. Google creates the duplicate in your Google Drive and opens it in a new tab.

The original document remains unchanged. Both documents are now in your Google Drive and synced across any device where you are signed into your Google account.

Understanding where your copy actually lives

When you duplicate a file on your computer, the copy exists only on that computer's hard drive. If you want the copy on another device, you have to manually move it or use cloud storage. The data never leaves your physical possession unless you choose to upload it somewhere.

When you duplicate a document in Word Online or Google Docs, the copy is stored on Microsoft's or Google's servers. Both companies back up your files, which means you cannot lose them to a hard drive failure — but it also means your document is stored in a data center you do not control. If you are concerned about where your data is kept, duplicating a local file and keeping it on your computer is the option that gives you the most control.

Neither duplication method changes what information is inside the document. If the original contains sensitive information, the copy will too. Make sure you understand what data is in the document before you share the copy with anyone.

What happens if you duplicate a document that is being edited by multiple people

If the original document is shared with collaborators in Word Online or Google Docs, the copy you make is a separate document. Changes made to the original after you duplicate it will not appear in the copy, and changes you make to the copy will not appear in the original. This is useful if you want to branch off a version for a different purpose, but it also means you now have two documents to keep track of.

If you duplicate a shared document and then want to share the copy with the same people, you have to set up sharing permissions on the copy separately. The copy does not automatically inherit the original's sharing settings.

Frequently Asked Questions

Can I duplicate a document that is password-protected?

Yes. The copy will also be password-protected with the same password as the original. If you want the copy to have a different password, you will need to open it, remove the original password, and set a new one through the File menu.

Does duplicating a document use up more storage space?

Yes. A duplicate takes up as much space as the original. If your original document is 5 MB, the copy is also 5 MB. If you are running low on storage, you may need to delete files you no longer need before creating duplicates.

What if I duplicate a document by accident?

On your computer, straightforward delete the copy by right-clicking it and selecting "Delete". In Word Online or Google Docs, right-click the file in your OneDrive or Google Drive and select "Delete". The original document remains unchanged.

Can I duplicate a document that someone else shared with me?

In Google Docs, yes — you can make a copy of any shared document, and the copy belongs to you. In Word Online, you can save a copy if you have edit permission. The copy is yours to keep, and changes to the original will not affect your copy.
