Private by design
Every tool runs offline on your phone. No uploads, no analytics, no tracking. Files leave your device only when you share them.
PDF reader and tools for Android
Every PDF tool.
Right on your phone.
Read, merge, split, compress, sign, scan and lock PDFs without uploading them anywhere. Your files stay on your device.
Free. No ads. No account.
What it does
Read
A fast reader with text search, night mode, and it reopens each file at the page where you stopped.
Merge
Combine several PDFs into one, in the order you choose.
Split
Pull out the pages or page ranges you need into a new PDF.
Organize pages
Rotate, delete and reorder pages, then save a clean copy.
Compress
Shrink large PDFs so they are easier to email and upload.
Images to PDF
Turn photos and screenshots into a single PDF.
Scan
Scan paper documents with the camera, with automatic edge detection.
Sign
Draw your signature once, add name and date stamps, and flatten them into the PDF.
Protect and unlock
Lock a PDF with a password using AES-256 encryption, or remove a password you know.
Free, really
No ads, no subscription, no watermarks, no sign in. Just open a file and get to work.
Only what you pick
Numo PDF opens files through the Android file picker, so it sees only the files you choose. No storage permission needed.
