## What it is
PDFsam Basic is a free, open-source desktop application for splitting, merging, rotating, mixing and extracting pages from PDF files. It is built with JavaFX, runs entirely offline so files never leave the user's computer, and is available for Windows, macOS and Linux.

## Use cases
- merge multiple pdf files into one
- split a pdf by page numbers or bookmarks
- extract specific pages from a pdf
- rotate pdf pages
- combine odd and even pages from a single-sided scanner
- split a large pdf into smaller files by size
- offline pdf manipulation without uploading files

## When to choose
- you need a free, no-watermark tool for everyday split/merge/rotate/extract tasks
- you want files processed locally with no internet connection or uploads
- you need a cross-platform (Windows/macOS/Linux) desktop PDF tool
- you need to interleave pages from two scanned documents

## When to avoid
- you need visual page thumbnail editing, compression, cropping or metadata cleaning (PDFsam Visual)
- you need full PDF editing, OCR, form filling or digital signatures (PDFsam Enhanced)
- you need programmatic/command-line PDF processing in a server pipeline
- you cannot use AGPL-licensed software
