SwifDoo PDF

What if you could edit, sign, and convert any PDF on your Android phone as easily as you work in Word?

SwifDoo PDF turns your mobile device into a full-featured PDF workstation. Whether you're a freelancer finalizing a contract on the go, a manager reviewing quarterly reports, or a student annotating research papers, this app delivers desktop-grade PDF capabilities directly in your pocket. No more emailing files to yourself or struggling with clunky converters. SwifDoo PDF gives you complete control over every page, every annotation, and every signature.

Core Functionality: Your All-in-One PDF Toolbox

SwifDoo PDF is engineered for efficiency. The app integrates a suite of powerful modules that let you perform complex document operations without switching between different tools. From creation and editing to conversion and protection, every feature is designed for a seamless, touch-optimized workflow.

• Full-Featured PDF Editor: Modify text, images, and links directly on the page. Use the built-in OCR (Optical Character Recognition) to make scanned documents searchable and editable. Adjust font sizes, colors, and alignment with precision controls.
• Advanced Conversion Engine: Convert PDFs to and from Word, Excel, PowerPoint, and images. The conversion algorithm preserves original formatting, tables, and layouts with high fidelity. Batch convert multiple files at once to save time.
• E-Signature & Form Filling: Create, save, and reuse your handwritten or typed signature. Place it anywhere on the document with a single tap. Fill out interactive PDF forms automatically, or add text fields to non-interactive forms.
• Document Security Suite: Protect sensitive files with AES 256-bit encryption and password protection. Redact confidential text permanently. Add watermarks (text or image) to assert ownership or mark documents as drafts.
• Page Management & Compression: Reorder, rotate, split, merge, or extract pages with drag-and-drop simplicity. Compress large PDFs to a fraction of their original size without sacrificing readability, making them perfect for email attachments.

Key Advantages That Make SwifDoo PDF Stand Out

• Lightning-Fast Performance: Open and render 1000+ page documents instantly. No lag when scrolling, zooming, or applying edits.
• Intuitive Touch Interface: All tools are accessible via a clean, bottom-anchored toolbar. Pinch-to-zoom, long-press for context menus, and swipe to navigate pages.
• Cloud Integration: Import and export files directly from Google Drive, Dropbox, OneDrive, and other cloud storage services. Your work syncs seamlessly across devices.
• Offline Capability: Edit, sign, and convert documents without an active internet connection. Process everything locally on your device for maximum privacy and speed.
• No Watermark on Exports: Unlike many free PDF tools, SwifDoo PDF does not add any promotional watermarks to your final documents, ensuring professional output every time.
