How to merge PDF files into one
November 3, 2026 1 min read
An application may ask for your ID, diploma and CV as one PDF instead of three separate files. Or you may want to keep a month of invoices in a single file. Merging a few PDFs takes just a few steps.

The Merge PDF tool joins your files from top to bottom in the order you add them. Text and images on the pages stay exactly as they are.
- 1Open the Merge PDF tool.
- 2Pick the PDFs you want to merge, or drag and drop them. You need at least two.
- 3Set the order with the arrows. The top file becomes the first pages of the new PDF.
- 4Press Merge PDFs and download the single file.
Getting the order right
Adding numbers like 1, 2, 3 to the start of the file names before you add them makes the order easy to get right. If you want to move or delete a page after merging, use the Reorder, delete, rotate PDF pages tool.
Photos and password protected PDFs
This tool only merges PDF files. If you have photos of a document, turn them into a PDF first with the Image to PDF tool, then merge it with the others.
A password protected PDF can't be merged. If you know the password, remove it first with the Remove PDF password tool, then merge.
Are your files safe?
Merging happens in your browser, on your own device. Your PDFs are never uploaded to a server, so it's fine for private files like IDs, contracts or medical documents. If the merged file is too big to send, shrink it with the Compress PDF tool.
