Open Dungeons RPG presents Lean PDF, a free PDF editor and viewer for Windows built for people who want powerful PDF tools without subscriptions, accounts, advertisements, or unnecessary clutter.
Lean PDF keeps the tools you actually use right in front of you. Open a PDF and immediately edit, merge, split, extract, optimize, sign, print, or reorganize it without hunting through complicated menus or uploading your documents to an online service.
A Full PDF Workspace Without the Subscription
Many PDF programs divide basic features across paid plans, browser tools, and cloud services. Lean PDF takes a simpler approach: install it on your Windows computer, open your file, and get to work.
Lean PDF includes tools for:
- Viewing and navigating PDF documents
- Editing text
- Replacing images
- Merging multiple PDFs
- Splitting PDFs into separate files
- Extracting selected pages
- Inserting and duplicating pages
- Rotating and reorganizing pages
- Optimizing and reducing PDF file size
- Linearizing PDFs for Fast Web View
- Running OCR on scanned documents
- Searching within PDFs
- Adding signatures
- Printing and saving documents
The interface is designed to keep these features visible and accessible. You do not have to switch between websites, open a marketplace, or dig through layers of panels just to find a common tool.
Private and Local
Lean PDF works directly on your computer. Your documents do not need to be uploaded to a website before you can edit, merge, split, optimize, or convert them.
That makes Lean PDF especially useful for personal records, business documents, game books, manuscripts, forms, and other files you would rather keep private.
There are:
- No required accounts
- No advertisements
- No monthly subscription
- No cloud upload requirement
- No artificial feature limits
Lean by Design
Lean PDF is not "lean" because important features were removed. It is lean because the friction, clutter, and unnecessary overhead were removed.
The application has an installed footprint of approximately 220 MB while still providing a broad collection of professional PDF tools. The goal is simple: give users a capable PDF editor that is fast to install, easy to understand, and pleasant to use.
Designed for Windows
Lean PDF is currently available for 64-bit Windows computers.
Supported systems:
Windows 10
Windows 11
The installer is digitally signed and distributed directly from OpenDungeons.com.
