Overview

KwikPDF is a fast, simple PDF tool for Mac. Merge multiple PDFs into one, split PDFs by page ranges, or compress large PDFs to reduce file size — all with a clean, native Mac interface.

The problem: macOS Preview can open PDFs but can’t merge multiple files or compress them effectively. Online tools require uploading sensitive documents to third-party servers. Professional tools like Adobe Acrobat cost $20/month for features you rarely use.

The solution: KwikPDF handles the most common PDF tasks locally on your Mac. No upload required, no subscription, just a simple tool that does exactly what you need.

Key Features

  • Merge PDFs — Drag and drop multiple PDFs to combine them into a single file. Reorder pages before merging.
  • Split PDFs — Extract specific page ranges (e.g., pages 5-10, 15-20) into separate files
  • Compress PDFs — Reduce file size while maintaining readability. Great for email attachments and uploads.
  • Native macOS App — Built with PyQt6, feels right at home on your Mac
  • Local Processing — All PDF operations happen on your machine. Your documents never leave your computer.
  • Fast & Lightweight — No bloat, no unnecessary features. Opens instantly, processes quickly.
