Paperwise
A private PDF toolkit that works fully offline. Every tool runs on your phone, so your files never leave it.
Android · Free · New in 2026
What you can do
Merge PDF
Join two or more PDFs into one, and drag them into the order you want.
Split PDF
Cut a PDF by page ranges like 1-4, 5-10, or make one file per page. A colored page grid shows which pages go into which file.
Image to PDF
Pick photos from your gallery or take new ones with the camera. Reorder them, then choose page size (A4, Letter or fit to image), orientation and margin.
Your files
Every PDF you make is kept in Paperwise. Open, share, save to your phone, rename or delete it.
Private by design
All PDF work happens on your phone. Files stay in the app's own folder until you share or save them. There are no ads, no accounts and no tracking. The internet is used only when you tap "Check for updates".
