Apple's Preview app in iOS 26 transforms iPhones into versatile document hubs. Users can now edit PDFs, add signatures, and scan files directly within a single app. The update consolidates tools previously spread across Files, Mail, and third-party apps, creating a unified workflow for common tasks like correcting text, inserting shapes, or cleaning up scans. For frequent mobile document handlers, this eliminates app-switching friction.

The app supports PDFs, images (JPEG/PNG/HEIC), and scans, with features like markup tools, form field detection, and page reordering. Scanning mode automatically detects document edges, producing clean PDFs in seconds. Users can insert new scans into existing documents, ideal for adding signed pages or missing information. Page controls allow reordering, cropping, and rotating without leaving the iPhone, while export options include compression for smaller file sizes.

Security features include password protection for sensitive files, and cloud syncing ensures edits appear across devices. The interface remains intuitive, with thumbnail previews and search tools for navigating long documents. For casual users, this reduces reliance on desktop software for basic paperwork.

Preview's arrival on iOS 26 fills a long-standing gap, offering macOS-like document management on mobile. By centralizing tools, Apple simplifies tasks like adding signatures or adjusting scanned forms. This update matters for productivity-focused users who need reliable document handling without carrying additional hardware.
