About PDF Merger
Managing multiple PDF files can be disorganized. Our free online PDF Merger allows you to quickly combine multiple PDF documents into a single, continuous file directly in your browser.
How It Works
The tool uses a local JavaScript library (like pdf-lib) to parse the binary structure of your uploaded PDFs. It extracts the pages from each document and appends them sequentially into a brand new PDF file, which is then offered for download.
Common Use Cases
- Combining separate chapters or sections into a complete eBook or report
- Merging scanned pages of a contract into a single document
- Compiling various financial receipts into one file for tax purposes
- Creating a unified portfolio from multiple project files
