Publisher to Word is a free app that can convert your Microsoft Publisher files into editable Word documents. This program is designed to help you view and edit your.pub files from anywhere on your device or the cloud. This app is compatible with all of the major cloud services, including Dropbox, Google Drive, Box, and OneDrive. You can also import your.pub files from your device or the cloud.
Once you’ve converted your Publisher file into a Word document, you can open it in any word-editor-compatible app, like Word or Google Docs. You can edit the document and then export it back to .pub, so you can continue working on the same document even if you’re using a different app.
If you have more than one publisher file, you can import them all into the same document.
