The Spark
I needed to split a large PDF into smaller pieces and didn't want to upload a personal or work document to some random website to do it. Every "free" online PDF splitter I found wanted an upload, an account, or a credit card. I just wanted a tool that ran on my own machine.
The Build
PDF Splitter is a small Python tool with two interfaces: a web app you run locally, and a command-line tool. Split by explicit page ranges, every N pages, or into N equal parts. Everything happens on your machine — nothing is uploaded anywhere. Built in about five minutes with Claude Code, and I've used it a handful of times since for exactly the problem that started it.
