Welcome to the PaperOtter Wiki!

PaperOtter is a local desktop toolkit for compressing, resizing, converting, and editing PDFs, images, and documents. Everything runs on your machine -- no uploads, no cloud, no telemetry.

If you're here, you're probably looking for detail that doesn't fit in the README. This wiki is the right place for that.


Not sure where to start? Common Tasks answers "how do I...?" questions directly: find your goal, not a tool name.

For everything else, the wiki is divided into a few sections:

  • Common Tasks: "how do I shrink a PDF for email", "how do I permanently black out sensitive text", and more: organized by goal, not tool name
  • Getting Started: what LibreOffice and Calibre are for, and how to install them per platform
  • Using PaperOtter: the four-step workflow every tool follows, with a dedicated guide for each of the 21 tools: how it works, what its settings do, and why it might not behave the way you expect
  • Troubleshooting: fixes for the most common errors

There's also an FAQ page answering common questions about privacy, dependencies, and installation.
