Looking for a way to merge PDF files using an API?

I'm working on a web application that allows users to upload PDF files. I'm trying to find a way to add an additional PDF to the one uploaded by the user, but I haven't been able to solve this task yet. I'm wondering if there's an external API available that would allow me to merge two PDF files together.

My application is built with Angular on the front end and Node on the backend. The uploaded files are stored in Dropbox using FilePicker.

Any help or suggestions would be greatly appreciated. Thank you!

Answer №1

For Linux users with an app, pdfunite is a helpful tool that may already be available on your system. Simply use the code below and specify as many input files as needed:

const { exec } = require('child_process');
const mergePDFs = exec('pdfunite input-1.pdf input-2.pdf input-n output.pdf', function(error, stdout, stderr) {
  if (error) {
    throw error;
  }
});
