Notes: The final merged file will be downloaded automatically with name as merged.pdf.
This online tool merges multiple PDFs into a single large PDF. This application runs entirely on the browsers without sending the PDF files to the server. So, you don't need to worry about the security of your PDF data.
The Merge utility takes care of maintaining the order of the PDF files that you have selected. It preserves the order in which the files were selected. After all the files are selected, click on the submit button, and the tool will automatically combine the PDF files and then download them in your browser.
As this tool completely runs in the browser, make sure not to hit the limits of the browser memory. Select only the required number of PDF files for joining.
