How It Works

Transform your PDFs in three simple steps

1

Upload Your PDF

Click the upload area or drag and drop your PDF file. The tool accepts any standard PDF document. Your file is processed entirely on your device - it never leaves your computer.

2

Choose Your Mode

Select between single-sided or double-sided generation mode based on how you plan to use the PDF. Single-sided is great for digital viewing and regular printing. Double-sided is optimized for duplex printing.

  • Single-sided: 3x3 grid on each page
  • Double-sided: Optimized for duplex printing
3

Download & Use

Your processed PDF downloads automatically when complete. Open it with any PDF viewer, print it, or share it with classmates. Each thumbnail includes the original page number for easy reference.

Tips for Best Results

Use for Text-Heavy PDFs

Works best with lecture slides, notes, and text documents. Images and diagrams remain clear at thumbnail size.

Print in High Quality

For best printed results, use high-quality or best-quality printer settings to maintain text clarity.

Process Large PDFs in Batches

For PDFs over 100 pages, consider splitting them first for faster processing on older devices.

Use Modern Browsers

Chrome, Firefox, Safari, and Edge all work great. Update to the latest version for optimal performance.

Common Questions

What if my PDF is very large?

Processing happens in your browser, so speed depends on your device. Most PDFs under 50 pages process in seconds. Larger files may take a minute or two.

Can I adjust the grid size?

Currently, the tool uses a 3x3 grid optimized for A4 paper. We're working on adding customization options in future updates.

Why use double-sided mode?

Double-sided mode arranges pages so they align properly when printed on both sides of paper, maximizing paper savings and creating a professional booklet-style output.
