Read your documents without interruptions. We will never show advertising.

Everything stays on your phone
The tools run on the device itself: your PDFs are never uploaded to a server.
Every NAPDF tool
Twenty features to sort out a PDF without a computer. All free, all inside the app and, except for saving a web page, all working offline.
Organize pages
Merge, split, reorder, rotate and crop: everything you need to get a PDF into shape.
-
Merge PDF
Combine several PDFs into one
Pick two or more files and NAPDF joins them into a single PDF, in the order you set. The app shows one card per document (PDF 1, PDF 2…) so you always know which one goes first.
-
Split PDF
Split a PDF into several files
Break a long document apart: one file per page, every so many pages, or by the ranges you choose. Handy when you only need to send one chapter or one invoice.
-
Organize pages
Reorder or delete pages
You see every page as a thumbnail: press and hold to move one, tap the X to delete it. The PDF is rebuilt in the new order.
-
Rotate PDF
Turn the pages of a PDF
Straighten pages that came out sideways or upside down, one by one or all at once. The rotation is saved into the file, not just shown on screen.
-
Crop PDF
Trim unwanted margins
Drag the crop box over the page and cut off the white borders of a scan. The text then reads much bigger on a phone screen.
Convert files
Turn PDFs into images, photos into PDFs, scan with the camera or save a web page.
-
PDF to JPG
Turn each page into an image
Convert a PDF into JPG images, one per page, ready to send over chat or upload where PDFs are not accepted.
-
JPG to PDF
Build a PDF from your photos
Pick several photos from the gallery and turn them into a single PDF, in whatever order you like. Great for sending receipts or notes as one tidy file.
-
Scan
Snap a photo and make it a PDF
Use the camera as a scanner: the app finds the edges of the paper, straightens the page and saves it as a PDF. Scan several pages in a row into the same document.
-
Web to PDF
Save a web page as a PDF
Paste an address and keep that page as a PDF, to read it later offline or to file it exactly as it looks today.
Edit and sign
Write, sign, number pages and stamp watermarks without opening a computer.
-
Add text
Write on top of the PDF
Add text anywhere on the document, choosing colour and size. Perfect for filling in a form with no real fields, or adding a note before forwarding it.
-
Sign PDF
Draw and place your signature
Draw your signature with a finger and drop it exactly where it belongs, at the size you want. Sign a contract from the phone, with no printing or scanning.
-
Watermark
Stamp text across every page
Lay a diagonal text over every page, such as "DRAFT" or "COPY", as faint or as strong as you like.
-
Page numbers
Add the number to every page
Number a document that came without page numbers, choosing where they go and which number to start from.
-
Forms
Fill in a form's fields
If the PDF carries fillable fields, the app detects them so you can type into each one and save the completed file, without printing it.
Security and privacy
Passwords and real redaction of sensitive data, with your files never leaving the phone.
-
Protect PDF
Set a password
Encrypt the document with a password: without it, the file will not open. Worth doing before sending a bank statement or anything with personal data.
-
Remove password
Remove a password you know
If you know the password and are tired of typing it, take it off and keep an open copy. It only works with the right password: NAPDF does not break protection on other people's files.
-
Redact
Erase data, don't just hide it
Mark what you want gone and NAPDF deletes the text inside the file instead of painting a black box over it. Redacted content cannot be copied or searched afterwards.
Advanced tools
Compress, recognise text in a scan and compare two versions of a document.
-
Compress PDF
Make the file smaller
Shrink a PDF by recompressing its images, with three levels depending on how much quality you want to keep. For when the file is too big to email.
-
Recognize text
Make a scanned PDF searchable
Run text recognition (OCR) over a scanned document and turn it into a PDF you can search and copy from. It reads both Latin and Devanagari script.
-
Compare PDF
Spot changes between two PDFs
Load two versions of the same document and the app tells you which lines were added and which were removed. No more reading two contracts side by side.
Except for “Web to PDF”, which needs the internet to fetch the page, everything else works offline and never leaves your phone.
NAPDF Links — share PDFs with a short link
Upload a PDF (up to 50 MB) from the app and get a short shareable link. The file stays available free for 30 days; then it is deactivated and can be recovered with a one-time payment based on its age. After one year it is permanently deleted.
| Age of the file | Price |
|---|---|
| First 30 days | Free |
| 31 to 60 days | US$1.99 |
| 61 to 90 days | US$4.99 |
