This document will walk you through the basics of pdfmake and will show you how to create PDF files in the browser. Otherwise you can always build it from sources. The most fundamental concept to be mastered is the document-definition-object which can be as simple as:. Name can be defined only by using metadata title property see Document metadata. By default paragraphs are rendered as a vertical stack of elements one below another.

It is possible however to divide available space into columns. Column content is not limited to a simple text. It can actually contain any valid pdfmake element. Conceptually tables are similar to columns. For dynamically generated content including page numbers, page count and page size you can pass a function to the header or footer:.

You could have figured out by now from the examplesthat if you set the content key to an array, the document becomes a stack of paragraphs. The problem with an array is that you cannot add styling properties to it to change fontSize for example. PDF documents can have various metadata associated with them, such as the title, or author of the document. You can add that information by adding it to the document definition.

Conclusion: Extends pdfkit, uses its own scripting commands to generate PDF from data. You must generate inline CSS yourself if you want to use it. Not as good as other solutions. Conclusion: Looks like a good solution. This script allows you to take "screenshots" of webpages or parts of it, directly on the users browser.

Conclusion: Converts HTML page exactly as you see it to a raster image, but the text is blurry and not selectable. Makes large files. Might be good for portions of an HTML file, like the images, but not good for text.

Text not selectable. Conclusion: I added this inwhile other options were first written about in I haven't tested PDFShift, but it looks like a great solution that supports "high-fidelity" conversion hopefully vector graphics where possible with page headers and footers.

I want to use pdfmake to download a whole html page into PDF. However, my page is mixed with highcharts,plain text,html and images. When I try to export my page, all the highchart part are missing rest is fine. Not sure if pdfmake is the best way to handle it or not. Can anyone help with this?

I guess you're trying to add your chart in the PDF with as-is. The problem is that it's canvas and it's badly rendered in. I already faced this situation, and my advice to you will be to firstly generate a supported image version of your chart.

In order to not make the pdf file too big, and to avoid pixels while zooming in it, I opted in for the SVG export. Here is a documentation and an example on how to get an SVG export of your chart. Going further: Since the data the chart was composed of was sensible data, I needed to set up my own export server. Hopefully, Highcharts provide a well documented and an official way to set you own export server up with different OS supports.
