imagetopdf-gui 2.0.0

A lightweight GUI application for converting images to PDF and PDF files to images

ImageToPDF

A lightweight GUI application for converting images to PDF and PDF files to images. Built with PySide6, PyPDF2, and PyMuPDF.

Features

• Image to PDF Conversion: Convert multiple images (JPEG, PNG) into a single merged PDF document
• PDF to Image Conversion: Extract individual pages from PDF files as JPEG images
• Batch Processing: Handle multiple images at once
• Automatic Duplicate Handling: Prevents overwriting files with automatic naming
• User-Friendly GUI: Intuitive interface with visual feedback
• File Validation: Validates file types, sizes, and paths before processing
• Logging System: Comprehensive logging for debugging and monitoring
• Output Organization: All converted files are saved in a dedicated output folder
• Error Handling: Robust error handling with user-friendly messages

Requirements

• Python 3.6 or higher
• PyMuPDF (fitz) - Required for PDF to JPEG conversion

Installation

1. Install Python Dependencies

pip install -r requirements.txt

2. Install PyMuPDF (Required for CLI tool)

pip install pymupdf

3. Run the Application

python ImageToPdf.py

Usage

GUI Application (ImageToPdf.py)

1. Convert Images to PDF:

   • Click on any "Image 1-12" button to select image files
   • Selected images will be highlighted in green
   • Click "Convert Images To PDF" to merge all selected images into a single PDF
   • Output file will be saved as Merged_PDF_[timestamp].pdf in the output folder

2. Convert PDF to JPEG:

   • Click "Convert PDF To JPEG" button
   • Select a PDF file
   • Each PDF page will be converted to a separate JPEG image
   • Output images will be saved in the output folder with naming format: Converted-PDF-page[number]_[timestamp].jpeg

3. Clear Selection:

   • Click "Clear All Selection" to reset all selected images

Command Line Tool (Python_Lib.py)

Convert PDF files to JPEG images from the command line:

python Python_Lib.py /path/to/your/file.pdf

This will extract each page as a separate JPEG image in the output folder.
