\ud83c\udfaf Project Objective<\/strong><\/h3>\n\n\n\n

To build a multi-functional PDF Toolkit<\/strong> using Python that can merge, split, rotate, extract text, and add watermarks<\/strong> to PDF files \u2014 similar to tools like SmallPDF<\/em> or iLovePDF<\/em>.<\/p>\n\n\n\n

\n\n\n\n

\ud83e\udde9 1. Overview<\/strong><\/h2>\n\n\n\n

PDFs are one of the most used document formats in the world.
A PDF Toolkit<\/strong> automates tasks like combining reports, splitting pages, extracting text, and adding watermarks \u2014 saving time and effort.<\/p>\n\n\n\n

\ud83d\udcbc Real-World Uses<\/strong><\/h3>\n\n\n\n
    \n
  • Combine invoices or reports into one file<\/li>\n\n\n\n
  • Extract text for analysis<\/li>\n\n\n\n
  • Add company logos or \u201cConfidential\u201d watermarks<\/li>\n\n\n\n
  • Rotate or reorder scanned pages<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    \u2699\ufe0f 2. Required Modules<\/strong><\/h2>\n\n\n\n

    We\u2019ll use PyPDF2<\/code> for handling PDFs, and auto-install it if missing.<\/p>\n\n\n\n

    # Auto-install required modules\ntry:\n    from PyPDF2 import PdfReader, PdfWriter\nexcept ModuleNotFoundError:\n    import subprocess\n    subprocess.check_call([\"pip\", \"install\", \"PyPDF2\"])\n    from PyPDF2 import PdfReader, PdfWriter\n<\/code><\/pre>\n\n\n\n
    \n\n\n\n
    \ud83e\udde0 3. Merge Multiple PDFs<\/strong><\/h2>\n\n\n\n
    def merge_pdfs(pdf_list, output_file):\n    writer = PdfWriter()\n    for pdf in pdf_list:\n        reader = PdfReader(pdf)\n        for page in reader.pages:\n            writer.add_page(page)\n    with open(output_file, \"wb\") as f:\n        writer.write(f)\n    print(f\"\u2705 Merged {len(pdf_list)} PDFs into '{output_file}'\")\n<\/code><\/pre>\n\n\n\n
    \ud83e\uddea Example:<\/h3>\n\n\n\n
    merge_pdfs([\"report1.pdf\", \"report2.pdf\", \"report3.pdf\"], \"merged_report.pdf\")\n<\/code><\/pre>\n\n\n\n
    \n\n\n\n
    \u2702\ufe0f 4. Split PDF into Individual Pages<\/strong><\/h2>\n\n\n\n
    def split_pdf(input_file):\n    reader = PdfReader(input_file)\n    for i, page in enumerate(reader.pages):\n        writer = PdfWriter()\n        writer.add_page(page)\n        output_filename = f\"page_{i+1}.pdf\"\n        with open(output_filename, \"wb\") as f:\n            writer.write(f)\n    print(f\"\u2705 Split '{input_file}' into {len(reader.pages)} pages.\")\n<\/code><\/pre>\n\n\n\n
    \ud83e\uddea Example:<\/h3>\n\n\n\n
    split_pdf(\"merged_report.pdf\")\n<\/code><\/pre>\n\n\n\n
    \n\n\n\n
    \ud83d\udd01 5. Rotate Pages<\/strong><\/h2>\n\n\n\n
    def rotate_pdf(input_file, output_file, rotation_angle=90):\n    reader = PdfReader(input_file)\n    writer = PdfWriter()\n\n    for page in reader.pages:\n        page.rotate(rotation_angle)\n        writer.add_page(page)\n\n    with open(output_file, \"wb\") as f:\n        writer.write(f)\n    print(f\"\u2705 Rotated all pages in '{input_file}' by {rotation_angle}\u00b0\")\n<\/code><\/pre>\n\n\n\n
    \ud83e\uddea Example:<\/h3>\n\n\n\n
    rotate_pdf(\"page_1.pdf\", \"rotated_page.pdf\", 180)\n<\/code><\/pre>\n\n\n\n
    \n\n\n\n
    \ud83d\udca7 6. Add Watermark to Each Page<\/strong><\/h2>\n\n\n\n
    def add_watermark(input_file, watermark_file, output_file):\n    reader = PdfReader(input_file)\n    writer = PdfWriter()\n    watermark = PdfReader(watermark_file).pages[0]\n\n    for page in reader.pages:\n        page.merge_page(watermark)\n        writer.add_page(page)\n\n    with open(output_file, \"wb\") as f:\n        writer.write(f)\n    print(f\"\u2705 Added watermark to '{input_file}' and saved as '{output_file}'\")\n<\/code><\/pre>\n\n\n\n

    \n\n\n\n
    \ud83d\udcdc 7. Extract Text from PDF<\/strong><\/h2>\n\n\n\n
    def extract_text(input_file):\n    reader = PdfReader(input_file)\n    all_text = \"\"\n    for page in reader.pages:\n        all_text += page.extract_text() + \"\\n\"\n    with open(\"extracted_text.txt\", \"w\", encoding=\"utf-8\") as f:\n        f.write(all_text)\n    print(\"\u2705 Text extracted and saved as 'extracted_text.txt'\")\n<\/code><\/pre>\n\n\n\n
