Image to PDF Generator

Here's an application that allows users to upload images from their gallery and generate a PDF from them. Users can reorder images, preview the PDF, and download it.

How It Works

This application allows users to:

1. Upload Images: Drag and drop or select multiple images from their gallery
2. Reorder Images: Drag images to change their order in the PDF
3. Generate PDF: Convert the selected images into a PDF document
4. Preview PDF: View the generated PDF before downloading
5. Download PDF: Save the PDF to their device

Key Features

• Drag and Drop: Easy image uploading with visual feedback
• Image Reordering: Intuitive drag-and-drop interface to arrange images
• PDF Generation: Client-side PDF creation using jsPDF
• Responsive Design: Works well on both mobile and desktop devices
• Error Handling: Clear error messages for invalid uploads or failures

Technical Implementation

• Uses react-dropzone for file uploads
• Uses @hello-pangea/dnd for drag-and-drop reordering
• Uses jsPDF for PDF generation
• Preserves image aspect ratios in the PDF
• Handles multiple image formats (JPG, PNG, GIF, etc.)

Adding Image Editing Features

Let's enhance the PDF generator with basic image editing capabilities including crop, rotate, and filters. I'll add an edit mode that allows users to modify their images before generating the PDF.

Image Editing Features Overview

I've added a comprehensive set of image editing capabilities to your PDF generator:

1. Rotate Images

• Rotate images 90 degrees clockwise or counterclockwise
• See a real-time preview of the rotation

2. Crop Images

• Interactive cropping interface with drag-and-drop functionality
• Resize the crop area by dragging the corners
• Preview the crop result before applying

3. Apply Filters and Adjustments

• Choose from several preset filters:

  • Grayscale
  • Sepia
  • Invert
  • Blur
  • Brightness
  • Contrast
• Fine-tune brightness and contrast with sliders
• See real-time previews of all filter effects

How to Use

1. Upload your images as before
2. Click the edit (pencil) icon on any image to open the editor
3. Use the tabs to switch between rotate, crop, and filter modes
4. Make your desired edits
5. Click "Save Changes" to apply the edits to your image
6. Continue with PDF generation as normal

The edited images will be used when generating your PDF, giving you more control over the final document's appearance.
