Does HTML to PDF support CSS and web fonts?

Yes. The PDF is rendered with Chromium, like printing in the browser, including CSS, web fonts, images and backgrounds.

How much smaller does a PDF get?

It depends on the images in the PDF. The headers x-fx-original-size and x-fx-compressed-size show both sizes; if compression does not help, you get the original back.

New

PDF tools: create, convert, compress and edit

Ten new functions cover the PDF tasks that automations need most: create PDFs from HTML, web pages or Markdown, reduce the file size, convert pages into PNG or JPEG, insert, remove and rotate pages, add a text watermark and read or set the metadata. They complement the existing merge, split and watermark functions.
