Merge, split & lock PDF offline - no upload, no ads. Compress & batch with Pro.
Read full description
Offline PDF Toolkit does everyday PDF jobs on your phone, and only on your phone. All PDF processing happens offline on the device and your documents are never uploaded.
FIVE TOOLS, FREE
MERGE PDFS
A PDF merger that stays on your phone: pick two or more files, set their order with the up and down buttons, and combine PDF files into one.
SPLIT OR EXTRACT PAGES
Use it as a PDF splitter: type a range like 1-3, 7 and keep just those pages. Or split the file every N pages, or into single pages.
ORGANIZE PAGES
See every page as a thumbnail. Move a page earlier or later, rotate pages, or delete them, then save the result as a new file.
IMAGES TO PDF
Turn photos of receipts, notes or forms into a PDF. Pick pictures in the photo picker or file picker, or take one with your camera app. JPG to PDF works like PNG: each picture becomes a page, at its own shape or fitted to A4 or Letter.
PASSWORD PROTECT OR REMOVE
Lock PDF files by adding AES-256 encryption to a copy, or remove a password you already know. The app never tries to guess, crack or bypass a password it was not given.
PRO: THREE MORE TOOLS, ONE-TIME UNLOCK
Pro is a one-time unlock, not a subscription: buy it once and it stays. The price for your country is shown before you pay, and the five tools above stay free either way.
EXPORT PAGES AS IMAGES (PRO)
Save a PDF's pages as picture files — PNG if you want them lossless, JPEG if you want them small — at screen quality (150 dpi) or print quality (300 dpi). Pick the folder they go into.
COMPRESS (PRO)
Make a PDF smaller by recompressing the pictures inside it, at a Smaller or a Balanced setting. It tells you the old size, the new size and how many images it actually recompressed, and you choose whether to save the smaller copy.
BATCH (PRO)
Apply one change to as many as 50 PDFs in a single run: turn every page, add a password, or remove a password you know. Every file is checked first and the ones that cannot take the change are listed rather than silently skipped. Each result is a new file.
WHY OFFLINE MATTERS
Most PDF tools upload your file to be processed somewhere else. Contracts, payslips, medical letters and ID scans are exactly the documents you would rather not put on another company's machine. Every tool here runs on the device, so the document never travels.
The app asks for no storage or camera permission and cannot browse your files or photos. It only sees what you choose in the Android file or photo picker, a photo you take with your camera app from Images to PDF, or a file shared to it from another app. Every tool works with no internet connection.
Your original is never modified. Every tool writes a new document and leaves the file you picked exactly as it was.
WHAT IT DOES NOT DO
It does not offer PDF to Word or Excel conversion.
Extracting pages into a new file keeps the page content, but bookmarks, form fields and attachments do not come along. The app tells you before you save if the file you picked contains any of them.
Any change to a signed PDF invalidates its signature, as it does in any PDF editor. The app warns you first.
It does not claim PDF/A conformance.
Compress works on the pictures inside a PDF. A document that is mostly text, or whose pictures are stored in a form this app will not touch, can come back the same size, and the app tells you so.
NO ADS, NO SUBSCRIPTION, NO ACCOUNT
The app is free to install and shows no advertising, and it does not collect an advertising ID. The only thing there is to buy is the one-time Pro unlock.
It does send crash reports and basic usage counts — which tool was opened, whether it finished, and whether you saw or completed the Pro purchase — so faults can be found and fixed. These never include your files, their names or their contents, and you can switch them off in the About screen. The network is used only for these reports and Google Play purchases.
