JSPDF: Weird PDF Format - javascript

I am using jsPDF to convert html into PDF file.
This is what it looks like from the browser:
This is the PDF file:
Here is my code:
const doc = new jsPDF();
doc.html(document.getElementById('print-content')!, {
callback: function (doc) {
doc.save(activeSales?.ID + '.pdf');
},
});
How to make it responsive when generating the pdf?
I want to generate it in A4 width.

i know this is too late, but I faced the same issue before.
You can use another library called jsPDF-AutoTable which will make it easier for you to work with tables.
Here's the doc : https://github.com/simonbengtsson/jsPDF-AutoTable

Why is jsPDF HTML to PDF export slow?

I'm using jsPDF to generate PDF files from HTML tables, but it takes more than one second to convert a simple table (5x10 cells) containing only text which is way too long for such a "simple" task. Below are the lines of code responsible for the conversion. What am I missing?
const doc = new jsPDF();
const htmlContent = liElements[i].firstChild as HTMLElement;
doc.html(htmlContent).then(() => {
const buffer = doc.output("arraybuffer");
resolve(buffer);
});
Don't have enough reputition to embedd an image, but here is an image of the profiler while exporting a 6 page pdf, where 4 pages use HTML.

Korean language not rendering on PDF while using JSPDF

I am using JSPDF library to generate pdf while working on korean language the letters are getting change in symbols and sometime empty. Could anyone please help me?
const doc = new jsPDF();
const myFont = ... // overhere i am inserting a string which is being generated using following link https://rawgit.com/MrRio/jsPDF/master/fontconverter/fontconverter.html(it's too long)
// add the font to jsPDF
doc.addFileToVFS("MyFont.ttf", myFont);
doc.addFont("MyFont.ttf", "MyFont", "normal");
doc.setFont("MyFont");
You can try directly print the HTML text element.

doc.save("new.pdf");

generate a pdf with input fields editable in angular

I have this code on javascript and angularjs to create an editable pdf whereby on the textfields the user may/can input data on the text-fields. The pdf documents download but the textfields are not edittable. Here is the snippet
var opt = {
margin: 0,
filename: name+'doc.pdf',
html2canvas: { scale: 2 },
jsPDF: { unit: 'in', format: 'letter', orientation: 'portrait' },
pagesplit: true
};
html2pdf().set(opt).from(element).save();
upon searching online I saw a related snippet that may achieve what am trying to do but its written in the php and do not know how to convert it to javascript/angular and test the snippet
$html2pdf = new HTML2PDF('P','A4', 'en', false, 'ISO-8859-15');
$html2pdf->pdf->SetDisplayMode('fullpage');
$html2pdf->writeHTML($content, isset($_GET['vuehtml']));
$html2pdf->Output('pdf_demo.pdf');
here is the library I am using
<script src="/static/pdf/html2pdf.bundle.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.min.js"></script>
Please how create a pdf with textfields edittable
It appears that you are using this library (it would have helped a lot if you had mentioned that). As far as I can tell from the documentation, that library converts the HTML to an image, and then turns the image into a PDF. So, it's not possible for the resulting PDF to be fillable.
You may need to do this server-side with a library based on wkhtmltopdf which appears to support generating fillable PDFs. Or, you may be able to directly create the PDF (i.e. skip the HTML) with jsPDF.

Is it possible to use custom Google web fonts with jsPDF

I'm using jsPDF (https://parall.ax/products/jspdf, https://github.com/MrRio/jsPDF) to produce dynamic PDFs in a web application.
It works well, but I'd like to figure out whether it's possible to use Google web fonts in the resulting PDF.
I've found a variety of links that are related to this question (including other questions on SO), but most are out of date, and nothing looks definitive, so I'm hoping someone clarify whether/how this would work.
Here's what I've tried so far, with no success:
First, load the font, and cache it as a base64-encoded string:
var arimoBase64;
var request = new XMLHttpRequest()
request.open('GET', './fonts/Arimo-Regular.ttf');
request.responseType = 'blob';
request.onload = function() {
var reader = new FileReader();
reader.onloadend = function() {
arimoBase64 = this.result.split(',')[1];
}
reader.readAsDataURL(this.response);
};
request.send()
Next, create the pdf doc:
doc = new jsPDF({
orientation: "landscape",
unit: "pt",
format: "letter"
});
doc.addFileToVFS("Arimo-Regular.ttf", arimoBase64);
doc.addFont("Arimo-Regular.ttf", "Arimo Regular", "normal");
doc.setFont("Arimo Regular", "normal");
doc.text("Hello, World!", 100, 100);
doc.save("customFontTest");
When the PDF is saved - if I view it in my browser - I can see the custom font. However - if I view it using Adobe Reader or the Mac Preview app - the fonts are not visible.
I assume that's because the font is rendered in the browser using the browser's font cache, but the font is not actually embedded in the PDF, which is why it's not visible using Adobe Reader.
So - is there a way to accomplish what I'm trying to do?
OK - I finally figured it out, and have gotten it to work. In case this is useful for anyone else - here is the solution I'm using...
First - you need two libraries:
jsPDF: https://github.com/MrRio/jsPDF
jsPDF-CustomFonts-support: https://github.com/sphilee/jsPDF-CustomFonts-support
Next - the second library requires that you provide it with at least one custom font in a file named default_vfs.js.
That file should look like this:
(function (jsPDFAPI) {
"use strict";
jsPDFAPI.addFileToVFS("[Your font's name]","[Base64-encoded string of your font]");
})(jsPDF.API);
I'm using two custom fonts - Arimo-Regular.ttf and Arimo-Bold.ttf - both from Google Fonts. So, my default_vfs.js file looks like this:
(function (jsPDFAPI) {
"use strict";
jsPDFAPI.addFileToVFS("Arimo-Regular.ttf","[Base64-encoded string of your font]");
jsPDFAPI.addFileToVFS("Arimo-Bold.ttf","[Base64-encoded string of your font]");
})(jsPDF.API);
There's a bunch of ways to get the Base64-encoded string for your font, but I used this: https://www.giftofspeed.com/base64-encoder/.
It lets you upload a font .ttf file, and it'll give you the Base64 string that you can paste into default_vfs.js.
You can see what the actual file looks like, with my fonts, here: https://cdn.rawgit.com/stuehler/jsPDF-CustomFonts-support/master/dist/default_vfs.js
So, once your fonts are stored in that file, your HTML should look like this:
<script src="js/jspdf.min.js"></script>
<script src="js/jspdf.customfonts.min.js"></script>
<script src="js/default_vfs.js"></script>
Finally, your JavaScript code looks something like this:
const doc = new jsPDF({
unit: 'pt'
});
doc.addFont("Arimo-Regular.ttf", "Arimo", "normal");
doc.addFont("Arimo-Bold.ttf", "Arimo", "bold");
doc.setFont("Arimo");
doc.setFontType("normal");
doc.setFontSize(28);
doc.text("Hello, World!", 100, 100);
doc.setFontType("bold");
doc.text("Hello, BOLD World!", 100, 150);
doc.save("customFonts.pdf");
This is probably obvious to most, but in that addFont() method, the three parameters are:
The font's name you used in the addFileToVFS() function in the default_vfs.js file
The font's name you use in the setFont() function in your JavaScript
The font's style you use in the setFontType() function in your JavaScript
You can see this working here: https://codepen.io/stuehler/pen/pZMdKo
Hope this works as well for you as it did for me.
I recently ran into this same issue, but it looks like the jsPDF-CustomFonts-support repo was rolled into MrRio's jsPDF repository, so you no longer need it to get this working.
I happen to be using it in a React App and did the following:
npm install jspdf
Create a new file fonts/index.js (Note: You can download the Google Font as a .ttf and turn it into the Base64 encoded string using the tool in mattstuehler's answer)
export const PlexFont = "[BASE64 Encoded String here]";
Import that file where you need it:
import jsPDF from 'jspdf';
import { PlexFont } from '../fonts';
// Other Reacty things...
exportPDF = () => {
const doc = new jsPDF();
doc.addFileToVFS('IBMPlexSans-Bold.ttf', PlexBold);
doc.addFont('IBMPlexSans-Bold.ttf', 'PlexBold', 'normal')
doc.setFont('PlexBold');
doc.text("Some Text with Google Fonts", 0, 0);
// Save PDF...
}
// ...
Just wanted to add an updated answer - for version 1.5.3:
Convert the font file to base64 = https://www.giftofspeed.com/base64-encoder/
const yanone = "AAWW...DSES"; // base64 string
doc.addFileToVFS('YanoneKaffeesatz-Medium.ttf', yanone);
doc.addFont('YanoneKaffeesatz-Medium.ttf', 'YanoneKaffeesatz', 'normal');
doc.setFont('YanoneKaffeesatz');
