Thumbnail view for PDFs is available in OneDrive and SharePoint on the web

OneDrive and SharePoint on the web will add a default-enabled thumbnail view in the PDF viewer by mid-August 2026, allowing users to visually browse and jump to PDF pages easily. No admin action or changes to permissions are required; organizations should update training and inform users. What and Why: We are improving PDF navigation in OneDrive and SharePoint on the web by adding a thumbnail view in the PDF viewer. Users will be able to open a thumbnail panel to visually browse pages in a PDF and jump directly to a selected page. This update helps users navigate long PDFs more quickly, especially when they need to find a visual section, page layout, chart, image, or form page without scrolling page by page.
