How to Merge PDF Files on Windows
On Windows, you can merge PDFs from a modern browser such as Edge, Chrome or Firefox. Upload the files, set their order and download one combined PDF.
Quick answer

- 2Choose the PDF files from File Explorer.
- 3Review the order in the file list.
- 4Merge the files.
- 5Save the downloaded PDF from your browser.
Why use a browser on Windows
Windows can open PDFs in Edge, but combining files usually requires another tool. LiftPDF handles the merge from the browser, so you do not need to install a separate desktop PDF editor for a simple merge.
This is useful on work computers where installing software is restricted or when you only need a quick one-time merge.
The file order controls the final PDF
The most important part of merging PDFs is sequence. The first file becomes the first section of the final PDF, the second file follows it, and so on.
Before you click Merge PDF, check the preview list and move files up or down until the cover page, main document, appendices and attachments are in the right order.
Where the downloaded file goes
Most Windows browsers save the merged PDF to your Downloads folder unless you choose another location. The file name is readable, so it is easier to find after export.
Privacy and browser processing
LiftPDF merges PDFs in your browser for supported files. The pages are copied locally into a new document, so the workflow does not require a document upload API.
That matters for contracts, invoices, reports and personal records. You still need to use good judgment with sensitive files, but avoiding a server upload is a practical privacy advantage.
