## Features Implemented:
1. **File Upload Interface**:
- Drag and drop functionality
- File selection button
- Visual upload area with hover effects
2. **Processing Simulation**:
- Animated spinner
- Progress bar
- Status text
3. **Result Display**:
- Success message
- Download button for repaired PDF
- Start over option
4. **Information Sections**:
- How-to guide with steps
- Reasons for PDF repair
5. **Responsive Design**:
- Works on different screen sizes
- Clean, modern UI similar to ilovepdf.com
## Limitations:
Note that this is a frontend implementation only. In a real-world scenario:
- The actual PDF repair would require server-side processing or a PDF library like PDF.js
- The current implementation simulates the repair process but doesn't actually modify the PDF
- For a complete solution, you would need to integrate with a PDF processing API or backend service
You can paste this entire code block into your Blogger HTML/JavaScript widget, and it will create a functional PDF repair tool interface on your page.
