How to Fix Cannot Upload Files to OneDrive Through a Web Browser

Product: OneDrive
Device & OS: not provided
Scenario: Attempting to upload files into a OneDrive folder using a web browser interface.
Observed behavior: Files dragged into the browser do not become available after seemingly uploading, and the Upload button does not work, even after verifying storage space, filenames, and clearing browser data.

Before you start

Verify your internet connection stability and ensure the files you are trying to upload do not exceed the 250 GB individual file size limit for OneDrive.

Solution 1Recommended

Switch Web Browsers and Change Networks

Use a different browser such as Microsoft Edge and connect to a different network to rule out browser-specific glitches or network restrictions blocking the upload.

Sometimes, browser extensions, hidden cached data, or specific network firewall rules can silently block file uploads to cloud services. Changing your browsing environment helps bypass these invisible blocks.

Open an alternative browser

Launch Microsoft Edge or another browser instead of the one currently failing (e.g., Google Chrome).

Switch your network connection

Disconnect from your current Wi-Fi or Ethernet and connect to an alternative network, such as a mobile device hotspot or a different Wi-Fi network.

Attempt the upload again

Navigate to the OneDrive website, sign in with your credentials, and try uploading or dragging the files into the folder again.

Network Restrictions: Corporate or public networks often have strict firewall rules that can block cloud storage uploads. Using a personal hotspot is a quick way to bypass these.

Solution 2

Use the OneDrive Desktop Sync Client

Bypass the web browser entirely by installing the OneDrive desktop application to sync files directly from your computer's local folder.

Frequently Asked Questions

What is the maximum file size limit for uploading to OneDrive?

Why does OneDrive say my file name is invalid during upload?

OneDrive restricts certain characters such as " * : < > ? / \ | in file and folder names. Ensure your file name does not contain these characters or any leading and trailing spaces before trying to upload.

Can firewall or antivirus software block OneDrive web uploads?
