I recently got an idea of making a billing application with React js and tried using JsPDF package for generating PDF file. But unfortunately, it doesn’t work with Tamil language fonts properly. So I was searching for a better npm package and got it working with PDFmake. Come let’s explore how to import font and create PDF file with PDFmake package.


  • We may need to install React js and also include PDFmake package in our project to get started,

npx create-react-app <project_name>
npm i pdfmake

  • Also you may need to download our required fonts(file with .ttf extension) from Google or where ever we have it available. I have download Tamil language font from here — Tiro font. By clicking on Download family button, you will get the fonts downloaded.

Converting font into base64 file:

  • First step will be converting the font into base64 file, so that we can use it in our PDF file.
  • Upload your downloaded font file(TiroTamil-Regular.ttf) into the following website — link.
  • Once done, you will get the file converted into base64 encoded text.
  • Copy that encode text.
Copy the text inside the text box

Exporting encoded font into our React project:

  • Create a file named “TrioTamil-Regular.js”.
  • Paste the copied encoded text and export the constant font,
export const font = "<your_encoded_text_should_be_pasted_here>"

Importing the the required font:

  • Now, its time to import the required font into our React js project.
  • Using below import commands, we will import the pdfmake and fonts to create our PDF file,
//importing pdfmake to generate our PDF file
import pdfMake from "pdfmake/build/pdfmake"
//importing the fonts whichever present inside vfs_fonts file
import pdfFonts from "pdfmake/build/vfs_fonts"
//importing the encoded font file into our project
import {font} from './TiroTamil-Regular'
//Making use of all the fonts defined
pdfMake.vfs = pdfFonts.pdfMake.vfs
//Adding our own font into the vfs
window.pdfMake.vfs["TiroTamil-Regular.ttf"] = font

Creating PDF file:

  • Inside App.js file of our react project, lets have only one <div> tag.
  • Inside <div> tag, create a button which will trigger a function named printPDF as below,
  • Now lets write our function printPDF() to generate PDF file,
  • Our final App.js file will look like below,

Generating PDF file from our project:

  • All set! We now need to start our React project with below command,
npm run start
  • Now you will get our react project home screen open with printPDF button in it,
  • Click on the printPDF button, you will get the PDF file with the text which you mentioned in the content.
