PDF Splitter

A modern, cross-platform GUI tool to split PDF files with support for smart ranges, cut points, and custom naming templates. Built with Python and PySide6.

I developed this shit after realizing that almost every piece of software out there actually charges money for something as dumb as splitting a PDF.

Note

Yes, the screenshot shows "PDF Splitter Pro".
Nooooooo... it’s not some shady 'Pro' nonsense. I probably typed it right after using some bloated "SamPDF Pro" nonsense and my brain glitched.
Too lazy to fix it now, so let’s just pretend it’s ironic branding, sorry...

Features

• Multiple Splitting Modes:
  • Smart Mode: Intelligently parse inputs (e.g., 2 4 to extract pages between 2 and 4).
  • Ranges Mode: Specify complex ranges (e.g., 1-3, 5, 8-10).
  • Cut Points Mode: Define points to cut the PDF into multiple documents.
• Theme Support: Switch between light and dark modes.
• Customizable Output: Define your own output directory and file naming patterns.
• Drag & Drop: Easily add PDF files by dragging them into the application window.
