PDF Splitter

Colour-Aware Printing

PDF Splitter cover

Overview

I built PDF Splitter to stop wasting ink on lecture notes. Drop in a PDF and it automatically separates the colour pages from the black-and-white ones, so each set can go to the right printer.

Features

  • Automatic separation: sorts colour and black-and-white pages for you.
  • Double-sided mode: can include the backs of colour pages, so duplex printing stays in order.
  • Large files: handles PDFs up to 50 MB and is optimised for documents of 40+ pages.
  • Private by default: files are encrypted in transfer and deleted automatically after processing.
