Why Use OneNote File Attachment?
Attaching files directly into your OneNote pages offers multiple advantages:
- Consolidate all related materials in one place
- Make notes more interactive and informative
- Access important documents offline
- Annotate PDFs and images directly within OneNote
- Share complete information with team members or classmates
Instead of just linking to a file stored elsewhere, you embed the content where it’s needed.
How to Attach Files in OneNote
Attaching files in OneNote is straightforward, and the method works in both OneNote for Windows and OneNote for Microsoft 365.
Steps:
- Open the desired OneNote page
- Go to the Insert tab in the ribbon
- Click on File Attachment
- Browse and select your file
- Choose one of the following:
- Attach File (adds an icon you can click to open)
- Insert Printout (adds the visual content of the file)
The file will be embedded on the page, and clicking the icon opens it in its default application.
Supported File Types
OneNote supports a wide range of file formats:
| File Type | Supported? | Display Option |
|---|---|---|
| Yes | Attach or Printout | |
| Word (.docx) | Yes | Attach only |
| Excel (.xlsx) | Yes | Attach or Printout |
| Images (.jpg, .png) | Yes | Embed directly |
| Zip (.zip) | Yes | Attach only |
Note: Avoid attaching large files to avoid syncing delays, especially in shared notebooks.
Difference Between File Attachment and Printout
- File Attachment inserts an icon linked to the file. You can open and edit it using the original program.
- Insert Printout renders the content as images directly on the note page. Best for PDFs and spreadsheets when you want visual references.
You can combine both options by inserting a printout for context and keeping the editable file attached.
Keyboard Shortcuts for Inserting Attachments
Currently, there is no dedicated default shortcut for attaching files in OneNote. However, you can use:
- Alt + N, F
Opens the “Insert File” dialog using the ribbon key tips.
For a more efficient workflow, consider using Quick Access Toolbar customization or creating macros with tools like AutoHotKey.
Tips for Managing File Attachments
- Use clear filenames so you can quickly identify content
- Keep attachments small to maintain fast syncing
- Create a dedicated section for “Resources” in each notebook
- Use tags like “Important” or “Reference” to locate files later
- Use version control by adding dates or version numbers in filenames
OneNote File Attachment Limits and Warnings
Keep these limitations in mind:
- Individual attachments are limited to 100 MB in OneNote for Windows
- Too many attachments can cause syncing issues in shared notebooks
