What is the PDF Merger Tool?
The PDF Merger is a free browser-based tool that combines multiple PDF files into a single PDF document. It is useful when you need to combine separately scanned pages, merge documents created by different applications, or organize several PDF files into one document. No software installation is required, and the merging process can be completed directly in your web browser.
How PDF Merging Works
This tool uses the pdf-lib JavaScript library to load the selected PDF files and copy their pages into a new PDF document. The original pages are kept as separate pages within the resulting file, while the selected documents are combined into a single PDF.
Because the processing takes place in your browser, the PDF files do not need to be uploaded to a remote server for merging. This can be useful when working with documents that you prefer to keep on your own device.

- Local Processing: PDF processing takes place directly in your browser, and your selected files are not uploaded to our servers as part of the merging process.

Frequently Asked Questions (FAQ)
A. The PDFs are merged in the order shown by the tool. If the tool provides file reordering controls, you can arrange the files before starting the merge. Otherwise, select or add the files in the order in which you want their pages to appear.
A. The practical limit depends on your browser and device because PDF processing takes place locally. Very large PDF files or documents containing many pages may require more memory and can take longer to process.
A. Merging PDF pages does not normally require converting the pages into images or reducing their resolution. The resulting PDF keeps the source pages as PDF content rather than creating a new image-based version of each page.
A. No. The PDF merging process is performed directly in your browser, and the selected PDF files are not uploaded to our servers as part of the merging process.
A. Yes. The tool can be used in modern mobile browsers. However, merging a large number of pages or very large PDF files may require more memory, so performance can vary depending on the device.
