The Common Problem: Too Many PDFs

Many teams regularly face this situation:

• Multiple PDF files need to be sent to a client
• The files must be shared in a specific order
• Everything needs to look professional and easy to follow

Traditionally, this might involve third‑party tools or manual work to merge documents together. Copilot removes that extra effort by handling the task directly inside Microsoft 365.

Using Copilot Chat to Combine PDF Files

Copilot Chat (web version) is used to solve the problem quickly:

• Multiple PDF files are uploaded into Copilot Chat
• A simple prompt asks Copilot to combine the PDFs into one document
• Copilot creates a single file with all documents merged together
• The finished document is saved to OneDrive
• A link to the combined PDF is provided, ready to share 

There’s no need to leave Microsoft 365 or manage files manually, Copilot takes care of it for you.

What Happens to Your Files?

Data security is an important consideration.

When files are uploaded into Copilot:

• They are not used to train the AI models
• The files are stored only within your OneDrive
• Existing Microsoft 365 permissions and security controls apply 

This means you’re working with your documents in the same secure environment you already trust for everyday business work.

Why This Feature Is So Useful

While this might seem like a small capability, it solves a very real and frequent business problem.

Combining PDFs with Copilot helps teams:

• Reduce time spent on admin tasks
• Send clearer, more professional documents to clients
• Avoid confusion caused by multiple attachments
• Keep files organised inside Microsoft 365

It’s especially useful for sharing reports, proposals, onboarding packs, training materials, or compliance documentation.
