Fix SharePoint File Upload Stuck at 0 Bytes
Question details
The user needs to resolve an issue where files uploaded to a SharePoint document library stall and remain stuck at 0 bytes.
- Product
- SharePoint
- Device & OS
- not provided
- Scenario
- Uploading documents to a SharePoint online library via a web browser.
- Observed behavior
- The file upload progress freezes indefinitely at 0 bytes and fails to complete, often caused by cached session data or corrupted browser cookies.
Ensure your internet connection is active and verify that the document you are attempting to upload is not currently open or locked by another desktop application.
Use Private Browsing or Incognito Mode
This quickly bypasses corrupted browser cookies and cached session data that might interfere with SharePoint uploads.
Using an Incognito or InPrivate window creates a fresh session without loading your existing browser cookies. If the upload works here, you will know that cached data in your main browser profile is causing the 0 bytes error.
Open your web browser and press Ctrl+Shift+N (Windows) or Cmd+Shift+N (Mac) to launch a new Incognito or InPrivate window.
Navigate to the Microsoft 365 portal, sign in with your credentials, and open the specific SharePoint document library.
Click the 'Upload' button or drag and drop your file into the SharePoint interface to see if the upload completes successfully.
Clear Browser Cache and Cookies
Removing stored browser data provides a permanent fix if Incognito mode successfully resolved the 0 bytes error.
Switch Networks and Escalate to Support
If browser troubleshooting fails, network restrictions or server-side issues may be blocking the SharePoint upload.

Frequently Asked Questions
Why do my files get stuck at 0 bytes when uploading to SharePoint?
This issue is most commonly caused by corrupted browser cookies, outdated cached session data, or network interruptions that prevent the SharePoint server from fully receiving your file data.
Does file size affect the 0 bytes upload error in SharePoint?
While the 0 bytes error is usually related to browser sessions, attempting to upload files that exceed your organization's specific SharePoint file size limits or timing out on a slow connection can also cause the upload process to stall.
Can antivirus software cause SharePoint uploads to fail?
Yes, overactive network security features or antivirus web shields may temporarily intercept the upload connection to scan the file, causing the browser's progress bar to freeze at 0 bytes.
