## What is Wonder PDF?

Wonder PDF is an all‑in‑one PDF tool for iOS. Edit, convert, watermark, and sign documents on the go—all in one app. Everything processes locally, so your files stay private and secure.

**Core Features**

**1. PDF Editing – Edit PDFs as Easily as Word Documents**

Fix typos, update content, swap images, and reorganize pages—all without the original source file. Annotate with highlights, underlines, strikethroughs, sticky notes, and freehand drawings to communicate feedback clearly. From final polish to team reviews, every edit lives directly on the PDF, keeping revisions simple and straightforward.

**2. PDF Toolkit – Your Complete Document Processing Hub**

A powerful collection of essential utilities in one place:

- **Merge**: Combine multiple contracts, invoices, or reports into a single, organized PDF for easy archiving and sharing.
- **Split**: Extract individual chapters or sections from lengthy documents by page range or bookmarks, distributing only what's needed.
- **Compress**: Reduce file size intelligently with minimal quality loss, making large files email-friendly and upload-ready in seconds.
- **Text Extraction**: Instantly recognize and extract text from any PDF, ready to copy, paste, translate, or repurpose—no more manual retyping.

**3. PDF Conversion – Break Down Format Barriers**

Convert a wide range of file types into high-quality PDFs while preserving original formatting, image resolution, and clickable links:

- **Photos to PDF**: Turn multiple images into a single PDF document—perfect for product catalogs, portfolios, or scanned receipt archives.
- **Documents to PDF**: Convert Word, PPT, and Excel files with one tap. Share your work as a universally accessible PDF, ensuring consistent formatting across any device or platform.
- **Web Pages to PDF**: Save entire web pages or specific links as PDFs for offline reading, research archiving, or sharing reference materials—with layouts and hyperlinks fully intact.

**4. PDF Watermark – Protect Your Work and Elevate Your Brand**

Add custom text or image watermarks with complete flexibility to suit any scenario:

- **Text Watermarks**: Enter any phrase—such as "Confidential," "Internal Use," "Draft," or your company name—and adjust font, size, color, opacity, and rotation angle. Apply across all pages or select specific ranges.
- **Image Watermarks**: Upload your company logo or brand mark as a watermark, ideal for business proposals, design portfolios, and marketing collateral to reinforce brand recognition.

Whether you're preventing unauthorized use, marking document status, or adding a professional touch to commercial proposals, watermarking is just a tap away.

**5. PDF Signature – Sign Documents Without Printing a Single Page**

Create and apply handwritten signatures effortlessly, completely eliminating the print-sign-scan cycle:

- **Draw Your Signature**: Use your finger or an Apple Pencil to sign naturally on screen, with adjustable stroke thickness and color to match your real pen style.
- **Import Signature Images**: Upload a scanned image of your physical signature to maintain a consistent personal brand across all documents.

**Subscription Service**
When you subscribe to the "VIP Subscription" service, you will enjoy the following benefits:
1. Unrestricted access to all features.
2. AI content recommendations based on usage habits.

Payment for subscriptions is straightforward—the user's iTunes account is credited immediately after confirmation of purchase and payment.
