ImageAndPDFMerger Tool

A Java utility tool for merging images and PDF files into a single PDF document with quality options.

Features

• Merges multiple PDF files into a single document

• Converts images to PDF pages and adds them to the document

• Creates two quality variants for image-containing PDFs:

- Document quality (optimized for smaller file size)

- Image quality (optimized for better image quality)

• Supports various image formats (JPG, JPEG, PNG, GIF, BMP)

• Automatically formats images to fit A4 page size with margins

Parameters

• input_folder_path: Path to the folder containing images and/or PDF files to process

Output Files

The tool will generate output files in the input folder:

• output_document.pdf:

- If both PDFs and images are found: merged PDFs + images optimized for size

- If only PDFs are found: merged PDFs

- If only images are found: images converted to PDF, optimized for size

• output_image.pdf:

- Created only when images are processed

- Contains images optimized for quality

Compilation

Compile the tool with all required libraries in the classpath:

javac -cp lib\*;. ImageAndPDFMerger.java

Example

java -cp .;lib\* ImageAndPDFMerger c:\kentivy\pickup

This will process all PDF and image files in the merge_folder directory and create output PDFs in the same location.

Quality Settings

The tool provides two quality settings for image processing:

1. DOCUMENT Quality: (output_document.pdf)

- Images are resized to 50% of original dimensions

- JPEG compression with quality factor of 0.5

- Optimized for smaller file size and document sharing

2. IMAGE Quality: (output_image.pdf)

- Original image dimensions preserved (scaled to fit A4)

- Lossless compression used

- Optimized for image quality and printing

How It Works

1. The tool scans the input directory for PDF and image files

2. PDF files are merged using PDFBox's PDFMergerUtility

3. Images are processed to fit A4 page dimensions with margins

4. Output files are created in the input directory

Error Handling

The tool will:

• Skip any files it cannot process

• Continue processing the remaining files

• Provide warning messages for skipped files

• Generate detailed error messages if the process fails
