As work and study increasingly shift to mobile devices, users are looking for applications that can handle complex document tasks without compromise. PDF Master, available for iOS, presents itself as a versatile solution designed to meet professional demands while remaining accessible on both iPhone and iPad.

A key strength of PDF Master is its professional document scanning functionality. The app uses automatic edge detection with live corner adjustment to capture documents accurately in real time. Batch scanning allows users to process multiple pages efficiently, while built-in enhancement filters—such as black & white, grayscale, and auto-brightness—improve readability. Perspective correction ensures that scanned pages appear flat and properly aligned.

Beyond scanning, the app offers comprehensive PDF editing features. Users can merge or split documents, reorder, rotate, or delete pages, and manage content with precision. PDF Master also supports reusable digital signatures, form filling, and a full suite of annotation tools, including text notes, highlights, and comments, enabling efficient document review and collaboration.

The inclusion of AI-powered OCR and text recognition further elevates the app. Supporting more than 12 languages, the OCR engine extracts text quickly and converts scans into fully searchable PDFs, all while preserving the original layout and formatting of the document.

Security remains a central focus. PDF Master operates with 100% offline processing, ensuring that sensitive files never leave the device. Users can apply password protection to PDFs for opening and editing, and the app requires no accounts and collects no data, reinforcing its privacy-first approach.

Organization is simplified through enhanced folder management. Custom folders allow users to structure their documents effectively, move files between locations, and save scans directly into chosen folders. The “Smart Photo-to-PDF” tool makes it easy to convert images into neatly organized PDF files.

For more advanced needs, PDF Master includes a range of professional tools, such as custom text watermarks, adding pages or images to existing PDFs, flattening annotations, detecting form fields, and managing pages using thumbnail previews for quick navigation.

The app’s productivity-driven design is optimized for iOS, offering a clean and intuitive interface complemented by haptic feedback, smooth animations, and drag-and-drop support across iPhone and iPad.

Performance is another area where PDF Master stands out. It is optimized to handle large PDF files efficiently, providing instant previews, background processing, and seamless native iOS integration for a smooth user experience.

By combining powerful scanning, advanced editing, strong privacy protections, and polished performance, PDF Master continues to position itself as a reliable, all-in-one PDF management solution for iOS users seeking professional results on the go.
