Why merge PDFs on a phone?

Most of us receive documents on our phones — invoices, tickets, scanned forms. Combining them into one PDF makes them far easier to email, print or upload. Doing it in the browser means no storage-hungry app and no account to create.

Step-by-step: merge PDFs on Android or iPhone

1. Open your mobile browser and go to the Merge PDF tool.
2. Tap the upload area and select two or more PDF files from your phone.
3. Drag the files into the order you want them to appear.
4. Tap Merge, then download the combined PDF straight to your device.

Tips for the best result

Put the files in the right reading order before merging. If the final file is large, run it through Compress PDF afterwards so it is easy to share over email or chat. To scan paper pages first, use Scan to PDF to capture them with your camera.
