Need to send one tidy document instead of five separate attachments? With PDF42 you can merge PDFs directly on your Android phone in under a minute.
Merge PDFs in 4 steps
- Open MergeIn PDF42, open Tools and tap Merge.
- Select your filesPick the PDFs you want to combine — you can add images (JPG, PNG) into the same document too.
- Reorder by draggingDrag the files into the exact order you want them to appear.
- Merge and saveTap Merge, then save or share the single combined PDF.
Most "merge PDF" tools — and many apps — upload your files to a cloud server to do the work, and some watermark the result. PDF42 merges on your device, so a contract or ID never leaves your phone, and the output carries no watermark.
Can I mix in images or reorder pages?
Yes. You can drop photos straight into the merge, and drag everything into the order you want before combining. After merging you can still reorder, rotate or delete individual pages.
Are my files uploaded anywhere?
No. The merge happens on your phone, so your documents aren't sent to a server. That matters most for anything sensitive — agreements, statements, personal IDs.
