## What it is
PaperKnife is a privacy-first PDF utility that merges, splits, compresses, encrypts, signs, and sanitizes PDFs entirely on-device with no server uploads. It ships as an Android app (Capacitor), a web app/PWA, and works fully offline.

## Use cases
- merge pdf files without uploading them
- compress a pdf offline
- split pdf pages locally on android
- remove metadata from a pdf for privacy
- password protect a pdf without a server
- convert pdf to jpg or png locally
- sign a pdf electronically offline

## When to choose
- you handle sensitive documents like IDs, contracts, or bank statements and don't want them uploaded anywhere
- you need PDF tools that work fully offline on Android or in the browser
- you want an open-source, ad-free, tracker-free alternative to online PDF sites

## When to avoid
- you need advanced PDF editing like OCR, form filling, or collaborative editing
- you require batch server-side processing of large document volumes
- you need iOS or desktop native apps
