Microsoft OneNote File Upload Size Limit and Workarounds

Product: Microsoft OneNote
Device & OS: not provided
Scenario: Attaching files, documents, or media to OneNote notebooks for syncing and sharing with colleagues or between personal devices.
Observed behavior: OneNote restricts individual file uploads and attachments to approximately 50 MB per file, prompting users to seek workarounds for inserting larger files.

Before you start

Before attempting to insert large files, ensure you have sufficient storage space in your OneDrive account, as all OneNote notebooks and their attachments consume your OneDrive storage quota.

Solution 1Recommended

Use OneDrive to Share Large Files in OneNote

Instead of embedding a large file directly into OneNote, upload the file to OneDrive and insert a shareable link. This effectively bypasses the 50 MB attachment limit.

Microsoft officially recommends linking to cloud-hosted files rather than embedding large files directly into your notebook. This keeps your notebook syncing fast and prevents corruption.

Upload the file to OneDrive

Open your web browser, navigate to the OneDrive website, log in to your Microsoft account, and upload your large file (over 50 MB) using the 'Upload' button.

Generate a sharing link

Once the upload is complete, right-click the file in OneDrive, select 'Share', and click 'Copy link' to generate a shareable URL.

Insert the link into OneNote

Open your OneNote application, navigate to the desired page, click on the 'Insert' tab, select 'Link' (or press Ctrl+K), paste your OneDrive link into the Address field, and click 'OK'.

Use OneDrive to Share Large Files in OneNote

Faster Syncing: Using links instead of direct attachments keeps your OneNote notebooks lightweight, ensuring they sync much faster across your mobile and desktop devices.

Solution 2

Compress Files Before Uploading

Reduce the size of your files to fit within the 50 MB limit by compressing them into a ZIP archive before attaching them to OneNote.

Frequently Asked Questions

Why does OneNote limit file uploads to 50 MB?

OneNote restricts direct file attachments to approximately 50 MB to ensure smooth and fast synchronization across your devices and to prevent excessive syncing delays or potential notebook corruption.

Does this 50 MB limit apply to all versions of OneNote?

Yes, the 50 MB file attachment limit generally applies across most OneNote clients, including OneNote for Windows 10, OneNote for Mac, and the iOS/Android mobile apps, because of how the backend service syncs data through OneDrive.

Can I store large video files directly in OneNote?

It is not recommended to store large video files directly in OneNote as they will quickly exceed the 50 MB limit. Instead, upload your videos to OneDrive or a video hosting platform like YouTube, and paste the video link onto your OneNote page to embed it.

How much total data can a single OneNote notebook hold?

A single OneNote notebook can theoretically hold up to 2 GB of data if stored on a standard consumer personal OneDrive account. However, individual file attachments within that notebook are still strictly subject to the 50 MB limit.
