Merge PDF: Combine PDF & Split

Need to put a few PDFs together or save just part of a document? Merge PDF and Split lets you merge files, split them into smaller PDFs, extract pages and add watermarks on your Android phone.

All document processing happens on your phone. Your PDFs are never uploaded, and the PDF engine is included with the app. There’s no account to create, no sign-in.

MERGE PDFS

• Choose multiple PDFs from your device or a file app
• Drag the files into the order you want
• Keep bookmarks from the original documents
• Use optional image compression with three quality levels to reduce file size
• Choose a name for your merged PDF

SPLIT PDF

• Enter page ranges, such as 1–8, 9–20 and 21–40, to save each section as a separate PDF
• Split at regular intervals, like dividing a 120-page document into 10-page files
• Save every page as its own PDF
• Use page thumbnails to see where you want to split

EXTRACT PAGES

Only need a few pages? Tap the ones you want and save them together in a new PDF. Your original document stays unchanged.

ADD A WATERMARK

• Use your own text or an image from your gallery
• Place it in the centre, top-left or bottom-right, or repeat it across the page
• Adjust the opacity, size and rotation, with eight colours available for text
• Check the preview before applying it
• Add the watermark to the whole document or a selected page range

FIND AND MANAGE YOUR FILES

Browse PDFs on your device, search by name or filter the list to show recent or processed files. You can open, share, rename and delete files from within the app.

The Activity section keeps a history of your jobs, including page counts and file sizes.

DEVICE AND DISPLAY OPTIONS

Merge PDF and Split works on Android 7.0 and newer. To help with memory use on older phones, it processes large documents using disk storage instead of keeping the entire document in RAM.

Choose a light or dark theme and one of four text sizes. The app is available in English, Indonesian, Hindi, Spanish and French.

WHERE YOUR FILES ARE SAVED

Finished files are saved to Download/PDF Merge & Split, where you can access them with your file manager or PDF reader. You can change the folder name in Settings.

PRIVACY

Your document contents, file names, folder names, watermark text and search terms are never collected or sent anywhere.

The app uses Google Firebase to send anonymous crash reports and basic usage statistics. These include which tools are opened, whether processing succeeds or fails, how long it takes, and details such as your device model, Android version and available memory. Counts and file sizes are reported only in broad ranges. No advertising identifier is collected.
