UtilityPDF

This software was created, totally free, to facilitate and collect in one place, some operations that are normally done on PDF files.

Features

Currently the possible operations are:

  • PDF Compression - Compress PDF files by adjusting the compression factor with 4 different quality levels (prepress, printer, ebook, screen);
  • Text Extraction - Extract text from PDF via OCR with support for multiple languages using Tesseract;
  • PDF Merging - Merge multiple PDF files following the sequence of adding files, creating a new combined PDF file;
  • PDF Conversion - Convert PDF files to editable DOCX and/or RTF formats. >>> No Office installation required <<< to convert. If PDF contains only images, output DOCX and/or RTF files will have only images. Use text extraction (with OCR) to convert text inside images.

Modern UI Interface 🎨

The application features a completely redesigned modern interface with:

Custom Controls

  • ModernCard - Stylish card containers with colored headers and rounded corners for each operation section
  • ModernButton - Smooth gradient buttons with hover effects and rounded borders
  • ModernProgressBar - Enhanced progress bar with percentage display and smooth animations
  • LoadingSpinner - Animated circular spinner for visual feedback during long operations

Visual Enhancements

  • Color-coded sections: Each operation has its own distinctive color theme:
    • 🔵 Text Extraction (OCR): Blue (#3498DB)
    • 🟣 PDF Merging: Purple (#9B59B6)
    • 🟠 PDF Compression: Orange (#E67E22)
    • 🟢 PDF Conversion: Teal (#1ABC9C)
  • Emoji icons throughout the interface for better visual recognition
  • Responsive layout with centered, organized panels
  • Smooth animations for loading states and transitions
  • Professional color palette with subtle shadows and modern styling

Multilingual Interface 🌍

The application now supports 7 languages with real-time interface switching:

  • 🇺🇸 English (default)
  • 🇮🇹 Italiano
  • 🇫🇷 Français
  • 🇩🇪 Deutsch
  • 🇪🇸 Español
