SysTools PDF Splitter is a desktop utility designed to divide or split PDF documents into smaller files, pages, or sections, efficiently and reliably. It is part of the broader SysTools PDF tools suite, which offers a range of PDF editing, extraction, and automation capabilities.

Key Features:

1) Split by Page Range / Page Count: You can split a PDF into multiple files by specifying a fixed number of pages per split, or by defining custom page ranges (e.g. pages 1–5, 6–10, etc.).

2) Split by File Size: To produce output files under a certain size threshold (e.g., < 2 MB each), this feature helps you manage file sizes for email or storage constraints.

3) Batch Mode / Multiple Files: You can load multiple PDFs or even entire folders and split them all in one run, saving time compared to doing each manually.

4) Maintain Original Formatting: The tool preserves layout, fonts, images, forms, and graphics in the split parts — so each resulting file looks like a natural subsection of the original.

5) Selective Page Extraction: Optionally, extract or split only certain pages (e.g. only even/odd pages, specific ranges) while discarding or skipping others.

6) Encrypted / Password-Protected File Support: SysTools PDF Splitter often supports splitting PDF files that are protected with user permissions (provided you supply the password). It may also bypass certain restriction policies (if allowed) without altering content.

7) Preview & UI Interface: A user-friendly interface allows previewing pages before splitting, viewing bookmarks, and adjusting split settings easily.

8) Cross-Platform / System Compatibility: Typically designed for Windows systems (with possible support for macOS in related SysTools products).

9) Safe & Offline Processing: Unlike online splitters, the tool works locally on your computer, ensuring sensitive or confidential documents never leave your system.
