Adobe is rolling out an integration that brings Acrobat PDF viewing and annotation tools into WhatsApp Web and the Windows WhatsApp app. Multiple outlets report that users can open PDFs directly within a chat window, review documents, and mark them up (including highlighting and annotating) without leaving WhatsApp. The update is designed to remove the usual “download first” workflow associated with viewing PDFs, while still supporting existing protections. Digital Trends specifically notes that the approach retains password protection and WhatsApp’s end-to-end encryption. NDTV adds that Adobe positions the feature for “review and collaborate” use cases inside chat, and that users can interact with documents in-app, including scrolling and zooming in a way that matches how PDFs are normally viewed. Small Business Trends frames the change as helpful for small businesses that need to review, edit, and share documents while staying in the messaging context. Adobe announced the integration, with reporting indicating that access begins on the day of the update.
