Book ID: Extract from the URL https://online.fliphtml5.com/{book_id}/

Example:

Options

• -o, --output FOLDER - Output folder name (default: book-id)
• -p, --pages N - Total pages (auto-detect if 0)
• --delay SECONDS - Delay between pages (default: 0.8)
• --no-pdf - Skip PDF creation, only download images

Examples

# Custom output folder
python downloader.py zbqjj/vduu -o my-book

# Download first 50 pages
python downloader.py zbqjj/vduu -p 50

# Images only, no PDF
python downloader.py zbqjj/vduu --no-pdf

# Faster download
python downloader.py zbqjj/vduu --delay 0.5

How It Works

1. Navigates to each page using direct URL navigation (#p=1, #p=2, etc.)
2. Captures images via network monitoring
3. Applies RTL page order fix for Hebrew/Arabic books (keeps first page, swaps pairs)
4. Converts images to PDF

Output

• Images saved as 0001.webp, 0002.webp, etc. in output folder
• PDF created as <output-folder>.pdf

Troubleshooting

pip install playwright img2pdf pillow
playwright install chromium

Pages not loading: Increase delay with --delay 1.5
