How to Merge PDF Files
Combining multiple PDF documents into one is simple. Add your PDF files using the file picker or drag-and-drop zone. Rearrange them into your preferred order using the arrow buttons, then click "Merge PDFs" to create a single combined document.
Why Merge PDFs?
- Combine related reports into one comprehensive document
- Merge scanned pages into a single file for easier sharing
- Consolidate invoices, contracts, or receipts
- Reduce the number of attachments in emails
- Create a single portfolio or presentation from multiple sources
Privacy and Security
This tool processes everything directly in your browser using the pdf-lib JavaScript library. Your PDF files are never uploaded to any server. The merge operation happens locally on your device, ensuring complete privacy of your documents.
Tips for Best Results
For optimal performance, avoid merging extremely large files (over 100MB each). If you need to reorder pages within a single PDF before merging, use the PDF Split tool first to extract the pages you need, then merge them back together in the correct order.
