Browser extension

Install the nctools browser extension for one-click conversion from any tab.

Our Manifest V3 extension runs the same conversion engines as the web app. It adds a toolbar button that converts the current page, a selection, or a linked file — without leaving your workflow.

What it can do

  • Save the current tab as a PDF.
  • Save the current selection as a PDF.
  • OCR any image on the page (right-click → 'Extract text with nctools').
  • Convert a PDF link in the page to Word or Excel without downloading first.

Install

Head to /extension for the download and installation steps.
