Turn web pages into PDF, EPUB, HTML, or Markdown documents with Percollate, a command-line tool.
About Percollate
Percollate is an open-source Node.js command-line tool that turns web pages into PDF, EPUB, HTML, or Markdown documents. It can be run on one or more URLs, but also accepts local file paths or HTML piped through standard input. Multiple pages are bundled into a single file by default, with an option to export each source separately.
The tool supports custom HTML templates and CSS stylesheets, command-line CSS overrides, optional titles, authors, covers, and a hyperlinked table of contents whose depth can be set. It requires Node.js 14.17.0 or later and is installed globally from npm; packaged versions are also available through community channels such as the Arch User Repository and some Docker images.

Percollate FAQ
What is needed to install Percollate?
It is a Node.js command-line tool requiring Node.js 14.17.0 or later, installed globally with npm install -g percollate.
Can several web pages be combined into one document?
Yes. Pages are bundled into a single file by default, and the --individual flag exports each source to a separate file instead.
Can content fetched by another command be converted?
Yes. HTML can be read from stdin using the - operand, for example piped from curl, and the --url option supplies the original address so relative paths resolve.
