# How to merge 2 or more PDFs into one file

> A simple step-by-step guide to merging 2 or more PDFs into one file on Android, iPhone, Windows and Mac — free and without installing anything.


Merging PDFs means joining several PDF files into one, so you can send, upload or print a single document. You don't need Adobe Acrobat or any app — a browser is enough.



## The quick way (any device)


- Open the Merge PDF tool.

- Tap or click Select PDF files and choose all the PDFs you want to combine. On a computer, hold Ctrl (Windows) or Cmd (Mac) to pick several at once.

- Drag the files into the order you want. The number on each card shows its position.

- Click Merge PDF, then Download PDF.

Your files are merged inside your browser, so they're never uploaded — useful for bank statements, ID documents and anything private.



## On an Android phone
Open the merge page in Chrome, tap Select PDF files and pick files from your phone storage or Google Drive. To change the order, press and hold a file for a moment, then drag it. The merged PDF is saved in your Downloads folder.



## On an iPhone or iPad
In Safari, tap Select PDF files, then Browse to choose from the Files app or iCloud Drive. After merging, tap Download PDF; you'll find the file in Files → Downloads.



## On Windows or Mac
Drag your PDFs from File Explorer or Finder straight onto the page. On a Mac you can also merge PDFs in the built-in Preview app: open the first PDF, show the sidebar thumbnails, and drag other PDFs into it — but the browser method works the same on every computer.



## Common problems


### "This PDF is password-protected"
Protected PDFs can't be combined until the password is removed. Open the file with its password in your PDF reader and use Print → Save as PDF to make an unprotected copy, then merge that copy.



### The merged file is too big
Run it through Compress PDF afterwards. If a form needs a specific size, use Compress PDF to 200 KB or set your own limit.



### One page is sideways
Use the rotate button on that file before merging, or fix single pages afterwards with Rotate PDF.



## Frequently asked questions


### How many PDFs can I merge at once?
There is no fixed limit. Dozens of files are fine on a computer; on phones, very large batches depend on your phone's memory.



### Does merging change the quality?
No. Pages are copied as they are, so text and images look exactly like the originals.
