The new Preview app in iOS 26 addresses a significant workflow gap for iPhone users by consolidating document management tools into a single, unified workspace. Historically, editing PDFs, adding signatures, and scanning files required juggling between the Files app, Mail, and various third-party applications, leading to a fragmented and inefficient user experience. This native integration is a major development for mobile productivity, streamlining tasks that were previously cumbersome on a smaller screen.

According to AppleInsider, Preview supports PDFs, images, and scans, allowing users to perform corrections, clean up documents, and insert signatures directly within one consistent interface. This move signifies a push toward making the iPhone a more capable tool for professional and administrative tasks, reducing reliance on external apps and enhancing the overall utility of the device for handling routine paperwork.
