Import the .onepkg File via OneNote Desktop Application

Bypass the web browser import errors by opening the notebook package directly in the desktop app and sharing it to OneDrive manually.

The web-based import tool often struggles with large or complex .onepkg files, leading to endless spinning. The desktop version of OneNote handles the extraction locally, which is much more reliable.

1
Open the .onepkg file

Locate the downloaded .onepkg file on your computer and double-click it to launch the OneNote desktop application.

2
Unpack as a local notebook

When prompted by OneNote, choose a location on your local hard drive to extract and save the notebook files. Click 'Create' to open it locally.

3
Share to OneDrive

Once the notebook is open and fully loaded, click on 'File' in the top-left corner, then select 'Share'. Follow the prompts to upload and sync the notebook to your OneDrive account.

Application Version Requirement: This process requires the traditional desktop version of OneNote (formerly OneNote 2016). The 'OneNote for Windows 10' app does not support opening local .onepkg files.

Frequently Asked Questions

What exactly is a .onepkg file?

A .onepkg file is a OneNote Package file. It acts as an archive (similar to a .zip file) that contains multiple OneNote notebook sections (.one files) compressed into a single, easily shareable file.

Why does the browser import page hang indefinitely?

The web browser import tool often encounters timeout errors or memory limits when attempting to extract the .onepkg archive and simultaneously upload its contents to OneDrive, resulting in a continuous loading loop.

Can I open .onepkg files on a Mac?

OneNote for Mac does not natively support opening local .onepkg files. You must first open the package on a Windows PC using the OneNote desktop app, share it to OneDrive, and then sync it to your Mac.
