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.
