Choose
Pick a file from your device — a PDF to edit, or a JPG/PNG to convert. Nothing is picked for you.
- 02
Process
Compress, merge, split, sign, or encrypt — the operation runs entirely on your device's processor. No data ever leaves it.
- 03
Save
The result is written straight to your device's local storage, ready to open, share, or print — exactly as you'd expect.
Typical PDF apps vs. OfflyPDF
The same task — removing two pages from a contract. Here's where your file actually travels in each case.
On-device
No network
permission
permission
Your file never moves
- Processed by your phone's own CPU
- No server exists to breach
- Retention governed by your storage
The difference isn't a stricter privacy policy — it's that OfflyPDF ships without the ability to send your files anywhere.
The full list
Permissions, in plain terms
Two requested, one deliberately absent. That's the whole list.
Camera
Scan to PDF only
Used only to photograph a physical page. The camera is never accessed in the background.
RequestedPhotos & Files
Only the file you pick
Used when you pick a file for Image to PDF, Image Signature, or the Workspace picker — never a background scan of your library.
RequestedInternet
Absent from the manifest
OfflyPDF has no networking code and cannot make a network call. Uploading your files isn't a promise we make — it's something the app is incapable of doing.
Not requestedEverything included
All features included
11 mobile app utilities built into one free PDF tool. Every task runs natively in this offline app with absolutely no ads.
PDF Workspace
A fluid reader with text search, page jump, pinch-to-zoom, and Light, Sepia, and Dark reading modes.
Scan to PDF
Camera capture with auto-crop and document filters: B&W Document, Grayscale, Magic Color, or Original.
Compress PDF
Three presets — Balanced, Extreme, and High Quality — repack content streams without uploading anything.
Merge PDF
Combine multiple documents, reorder them before merging, and keep the original page geometry intact.
Split PDF
Type exact page ranges like 1-4, 7, 10-12 to extract precisely the pages you need.
Page Organizer
Drag to reorder, rotate any page 90°, or remove pages you no longer need.
Sign & Stamp
Draw a vector signature, overlay an image signature, or apply a password-protected PKI certificate (.pfx/.p12).
Image to PDF
Batch-convert JPG and PNG images into a single shareable PDF, downsampled at source.
Watermark
Add a text watermark with independent opacity and rotation controls for consistent branding.
Protect PDF
Apply AES-256 encryption with a distinct owner password, computed entirely on-device.
Extract Pages
Keep or delete specific pages, with a guard against ever saving an empty document.
Answers
Questions worth asking first
Straight answers, grounded in how the app actually works — not in what a privacy policy promises.
No. OfflyPDF's Android manifest does not request the INTERNET permission, so the app has no way to send a file anywhere even if it tried. Every operation — scan, merge, compress, sign, encrypt — happens in local device storage.
