Using Percollate to download web pages as PDF

The basic commands available are:

• percollate pdf: Bundles one or more web pages into a PDF
• percollate epub: Bundles one or more web pages into an epub
• percollate html: Bundles one or more web pages into an HTML file

Available options are:

• -o, –output – The path of the resulting bundle; when omitted, the output file name is derived from the title of the web page.
• –individual – Export each web page as an individual file.
• –template – Path to a custom HTML template
• –style – Path to a custom CSS
• –css: Additional CSS styles you can pass from the command-line to override the default/custom stylesheet styles

See below Examples

Transform a single web page to PDF:

percollate pdf --output file filename.pdf https://example.com

To bundle several web pages into a single PDF, specify them as separate arguments to the command:

percollate pdf --output filename.pdf https://example.com/page1 https://example.com/page2

You can use common Unix commands and keep the list of URLs in a newline-delimited text file:

cat urls.txt | xargs percollate pdf --output filename.pdf

To transform several web pages into individual PDF files at once, use the –individual flag:

percollate pdf --individual --output some.pdf https://example.com/page1 https://example.com/page2

Set Custom page size / margins

The default page size is A5 (portrait). but you can use the --css option to override it using any supported CSS size:

percollate pdf --output some.pdf --css "@page { size: A3 landscape }" http://example.com

Similarly, you can define using:

Custom margins: @page { margin: 0 }
The base font size: html { font-size: 10pt }

Or any other style defined in the default/custom stylesheet.
