DIV to PDF, Iframe to PDF using JavaScript Only (with CSS & Images Support)

Using vanilla JavaScript only, convert DIV, page or iframe content into PDF and direct download it. No jQuery needed. I will go through a series of techniques to generate PDF from page or section of page or from iframe using JavaScript and some libraries but not any jQuery plugin.

I will use jQuery for selectors only. Other than that, no jQuery required. You can replace jQuery selectors with vanilla JavaScript selectors. At the bottom I have shared two versions of code - with and without jQuery. So This technique is not dependent on jQuery.

I have linked Bootstrap and jQuery. I have my custom js file for custom JS script. Use localhost or live server to test and develop this. Simple page url in web browser from local machine may not work properly. I am using localhost from vscode via an extension.

⭐1- Window Print
Let's generate PDF for the index page. Use simple print function on window object. It's not jQuery window, it's just window object - in vanilla javascript. This will fire up the window with print option and PDF download option.

⭐ 2- Window print on iframe
How about using same technique to generate PDF from iframe. iframe is loading another page that is receipt page. just use contentWindow on iframe element and use print function. Again this is vanilla JavaScript. So this is working but there is an issue.

Original webpage has background color for the table head. But the PDF is without background color in table head. We can use print specific media query and use dark text color for the text inside table head. This solves the issue but not quite.

And CSS for print color adjust exact is also not working in this case. Not even with asterisk and not even with important rule. So I am bound to change the style for print to adjust PDF. So it works as well with some tweak.

⭐ 3- jsPDF & html2canvas / Generating PDF from DIV on Same Page
We will use jsPDF and html2canvas to generate and download PDF from the webpage. It will be direct download. No prompt or confirmation window. All by using JavaScript. We are using two libraries - one is jsPDF and other is html2canvas. By using these javascript libraries, we can generate PDF from a page or from a portion of page and direct download it - using only javascript.

Note the versions of these libraries. These are CDN inks. jsPDF version is 1.3.4 and html2canvas version is 1.3.4. Use same versions if you are following along with this tutorial. Older versions will not work. They had different settings. Mind the versions here.

We use html2canvas library to get the canvas for required section that we are going to get PDF from and convert it into base64image image. Then we are using jsPDF and p is document orientation. p means portrait and px is for pixels.

If we look at A4 document size in pixels it's around 3508px and 2480px. I have proportionally decreased it down to meet our needs here. So 1600, 1131 is width and height in pixels. You will have to adjust these according to your need.

Then we used addImage function to draw base64image over pdf. 15 is left and top margins. 1110 and 381 are width and height. This is approximate width and height of my HTML content area. We used save function to download pdf and named it as well.

You will have to play with the width and height to adjust it - I have adjusted it according to my need that is serving me in my example. By using html2canvas we converted required area into base64image and then we applied addImage fnction, and save function to direct download pdf.

⭐ 4- jsPDF & html2canvas / Generating PDF from iFrame Content / External Page
Just use additional contentWindow on iframe in above script and you are good to go. And now we will have our receipt downloaded as PDF document. Images and backgrounds and colors and everything.

So this is how we can generate PDF and direct download PDF from a page, from content on page or from an external page.

Thanks so much for your video, what really helped me the most was about the correct versions of JSPDF and HTM2CANVAS, saying that i wiould also say that the PDF files for one page A4 even reducing the coordinates where never < 20MB in size, I change the PNG format to JPEG in both JSPDF and HTM2CANVAS and the file went down to 400Kb - just a tip!

Perfect explanation. Been trying to do it for a while now. Couldn't find a good resource that explains it well. Well, finally I got to understand how it works. Thanks a lot, man! Wish you health! ❤

I dont want to use html2canvas library as i want same quality, being able to select text as i am able to do with Ctrl + P ( window.print()) method, but want to use any different library. Also, i want to keep the Download button at different webpage and donwload as PDF another webpage, is this possible.
Note: I am using Angular and The data for my webpage is completely dynamic, and the data is coming from Backend by sending some Requests Headers.
Will it be possible to download a webpage lets say at - #/print/layout/ and have a download button at - #/project/

I treat PDF as zip, bz2, arj, ...

IF Apache web-server or MS IIS or ... is configured to serve PDF and browser have PDF plug-in, then the webpage-script to PDF is pack-compress for delivery efficiency.

JS in old and newer, are prone to china-hackers...
