Add a Password to a PDF with Nodejs / Javascript

Intro

API2PDF is a REST API that provides utilities for manipulating PDFs and other files. You landed here because you just want a simple and reliable way to add passwords to PDF files as a nodejs developer.

Our API will take your .pdf file and return back to you a new .pdf file with the bookmarks added. Just make sure your PDF is saved as a .pdf file and accessible at a URL that our service can ingest. For example, see this: http://www.api2pdf.com/wp-content/uploads/2021/01/1a082b03-2bd6-4703-989d-0443a88e3b0f-4.pdf — Ideally a file storage provider like S3 or Azure Blob Storage. See the code sample below.

Add a password to a PDF with Node / Javascript

Step 1) Open up your package manager and run the command

npm install –save api2pdf

Step 2) Grab an API key from https://portal.api2pdf.com. Only takes 60 seconds.

Step 3) Use the sample code below and replace “YOUR-API-KEY” with the api key you acquired in step 2.

var Api2Pdf = require('api2pdf');   
var a2pClient = new Api2Pdf('YOUR-API-KEY');

var url = 'http://www.api2pdf.com/wp-content/uploads/2021/01/1a082b03-2bd6-4703-989d-0443a88e3b0f-4.pdf';
var userpassword = "hello";
a2pClient.pdfsharpAddPassword(url, userpassword).then(function(result) {
    console.log(result);
});

And that’s it! Modify the code as you see fit. Hopefully this saves you time and makes adding passwords to PDF files easy and painless for those writing node / javascript code.

We have a whole nodejs based client library for our API that does a lot more than just this. Check out the full library capabilities here: https://github.com/Api2Pdf/api2pdf.node
