How to merge PDF files on an iPhone or Android phone

You do not need an app to join PDFs on a phone. A browser is enough, and the files stay on your phone the whole time. This works the same on iPhone, iPad and Android.

Steps

1. Open the Merge PDF tool in your phone browser (Safari or Chrome).
2. Tap "Choose a file" and pick your PDFs from Files, iCloud Drive or Google Drive. You can pick several at once, or add them one by one.
3. Put the files in the order you want. Use the arrows next to each file to move it up or down.
4. Tap the merge button and wait a few seconds.
5. Tap Download. On an iPhone the file goes to the Downloads folder in the Files app.

Open the tool: Merge PDF

Good to know

• If a file is protected with a password, remove the password first. This site cannot open locked files.
• Very big files (hundreds of pages) can be slow on older phones. Merge them in smaller groups.
• Check the pages once before you send the result to someone.
