PDF Merge

Combine multiple PDFs into one PDF. The files remain in your phone/computer only and are not uploaded anywhere.

How to use PDF Merge?

The job of PDF Merge is to combine pages from multiple PDF files into one document. This facility is provided in a separate page on PDF Saathi Hub so that you can read the correct input, output and required limits. The method written below is according to the actual tool's behavior, there is no guarantee of perfect conversion or approval.

Steps and output

Select at least two PDFs. Fix the file order with the up and down buttons, then merge. Result: merged PDF. Set aside a safe copy of the original file before starting work. Selecting the wrong page or version may require rework, so match the file name and content first. Start with a small sample first. Do not close the tab while the tool is running. If you see an error, read it; Do not consider getting incomplete results as success.

Where is caution necessary?

The file order of PDFs determines the page order of the entire output. Fix password-protected or damaged files first. The original signature validity of digitally signed files is not claimed to survive in the new merged copy. After downloading, open the new file in a separate viewer. Match page count, orientation, small text, names, dates and important numbers with the original document. Mere downloading of the file is not proof of correct result. If the output is to be sent to a government form, office, school or customer, also check the current file-size and format requirements of that place. If important information has been cut out, appears too light or is misplaced, recreate it from the original.

Privacy and safe use

In this tool, document processing happens in your browser. The file and password are not sent to any conversion server. For the first time, internet is required to download engine files; OCR language data is also downloaded. Ads, chat and translation are separate online features of the site. Putting a private document into AI chat or translation is not the same as local PDF processing. Work only after reading the limits given on this page. Browser memory is different on every device, so no fixed speed or guaranteed result can be given for very large files. Download the new file after processing. Complete the test before replacing the original. Change someone else's document only if you have their permission.
