Yes, Copilot can read PDFs: Microsoft Copilot and GitHub Copilot both let you add a PDF to a prompt and ask Copilot to summarize it or answer questions about it.
As of November 15, 2026, according to Microsoft and GitHub documentation:
- Microsoft Copilot (work or school): in Copilot Chat, select Add and manage sources, then Upload images and files, or attach a PDF from OneDrive, per Microsoft Support. PDF is a supported format for summarizing, document drafting, presentations and videos.
- Personal, Family, Premium and Pro: Copilot reads PDFs in Word, pulls content from PDFs into PowerPoint slides and references PDF attachments in Outlook.
- Tips: local file paths are not supported, and Microsoft suggests splitting a very large PDF into smaller files for more precise answers.
- GitHub Copilot: image and PDF attachments are available on all plans and enabled by default; select a model that supports image input.
