Frequently Asked Questions

Why does my Copilot Pro interface only let me upload images?

In certain web interfaces or standalone clients, the file upload support may be limited to images. To upload and analyze documents or PDFs, you typically need to use Copilot integrated within supported Microsoft 365 apps like Word or PowerPoint.

Do I have to use OneDrive to upload PDFs to Copilot Pro?

Yes, currently Copilot in Microsoft 365 apps usually requires you to upload your files to OneDrive first. This allows the AI to reference them as cloud attachments during analysis.

Can Copilot Pro analyze local PDFs directly from my computer?

Generally, Copilot Pro cannot directly reference local files from your hard drive. Local files need to be uploaded to Microsoft's cloud services (like OneDrive or SharePoint) before they can be analyzed.

Which Microsoft 365 apps support referencing files with Copilot?

Applications like Microsoft Word, PowerPoint, and Excel support file referencing with Copilot Pro, allowing you to generate content or analyze data based on your attached cloud files.
