How to merge PDF files on your Android phone
By Toolverse Labs, makers of PDF Tools · · 2 min read
Quick answer
To merge PDFs on Android, open PDF Tools, tap Merge, tap Choose PDFs and select the files, drag them into order, then tap Merge and name the result. The originals are not changed.
Many application forms accept only one file: “upload all documents as a single PDF”. Merging on a phone used to mean a website that uploads your ID and marksheets to someone else’s server. PDF Tools merges them on your phone.
Steps to combine PDF files
- Open PDF Tools and tap Merge under Quick tools.
- Tap Choose PDFs and select two or more files.
- Drag the handles to put them in order; they are joined from top to bottom.
- Tap Merge, name the new file and tap Save.
You can also start from the Files tab: long-press one PDF, tap the others and choose Merge.
Merge photos and PDFs together
Have a mix of photos and PDFs? Turn the photos into a PDF first with Images to PDF, then merge everything.
After merging
- Compress the merged file to fit an upload limit.
- Organise its pages: reorder, rotate or delete.
- Add a password before you send it.
Good to know
- Pages are joined as they are: their sizes and orientation are kept.
- The original files are not changed.
- Merging happens on your phone; nothing is uploaded.
