Welcome folks today in this blog post we will be encoding local pdf file or from url to base64 string in javascript and node.js. All the source code of the application is given below.

Get Started

In order to get started we need to install pdf-to-base64 library by using the npm command

npm i pdf-to-base64

After installing this library make a index.js file and copy paste the following code

index.js

from local pdf file

const pdf2base64 = require('pdf-to-base64');
pdf2base64("test/sample.pdf")
    .then(
        (response) => {
            console.log(response); //cGF0aC90by9maWxlLmpwZw==
        }
    )
    .catch(
        (error) => {
            console.log(error); //Exepection error....
        }
    )

Here we are taking the example of local pdf file where we provide the path of the pdf file which is present inside the computer and then it converts to base64 string using this library.

If you run the node.js project by running the index.js file by running the following command

node index.js

Converting URL PDF to Base64

Now we will be converting a url pdf document where user will provide the link of the pdf document and then we will be converting to base64 code

const pdf2base64 = require('pdf-to-base64');
pdf2base64("http://www.africau.edu/images/default/sample.pdf")
    .then(
        (response) => {
            console.log(response); //cGF0aC90by9maWxlLmpwZw==
        }
    )
    .catch(
        (error) => {
            console.log(error); //Exepection error....
        }
    )
