How to combine multiple PDFs into one file on Android

You don't need special software to combine multiple PDFs into one file on Android. FernPDF runs entirely in Chrome on Android: open the tool, drop your file, download the result. The merged file is assembled in your browser's memory and downloads instantly. It never touches a server.

On Android, you tap the drop zone to open the native picker, then choose Google Drive, Downloads, or your device's local storage. Once the combined document is ready, it downloads to your Downloads folder, opened from Chrome's download tray, or from the Files by Google app if your phone doesn't show a Downloads shortcut.

File management varies by manufacturer (Samsung's My Files, stock Android's Files by Google, and others), but the picker itself stays consistent: it's the same system dialog Chrome always uses, regardless of phone brand.

Works with files from Google Drive, Downloads or local storage. Because nothing uploads, it's quick even on mobile data, because you only pay bandwidth for the page itself.

Every FernPDF tool processes files in your browser: read how the privacy model works, or verify it yourself in your network tab.
