Hello, @Chokka

Please try this code, To convert Encode64 to PDF file using notepad++ :

// The Base64 string of a simple PDF file
var b64 = 'qWbOvwrMwEm+qrA30N6zFIMdzO/mW5zRN44s26ZLnQdSAs8CmVuZHN0cmVhbQplbmRvYmoKc3RhcnR4cmVmCjE5NzExCiUlRU9GCg==';

// Decode Base64 to binary and show some information about the PDF file (note that I skipped all checks)
var bin = atob(b64);
console.log('File Size:', Math.round(bin.length / 1024), 'KB');
console.log('PDF Version:', bin.match(/^.PDF-([0-9.]+)/)[1]);
console.log('Create Date:', bin.match(/<xmp:CreateDate>(.+?)<\/xmp:CreateDate>/)[1]);
console.log('Modify Date:', bin.match(/<xmp:ModifyDate>(.+?)<\/xmp:ModifyDate>/)[1]);
console.log('Creator Tool:', bin.match(/<xmp:CreatorTool>(.+?)<\/xmp:CreatorTool>/)[1]);

// Embed the PDF into the HTML page and show it to the user
var obj = document.createElement('object');
obj.style.width = '100%';
obj.style.height = '842pt';
obj.type = 'application/pdf';
obj.data = 'data:application/pdf;base64,' + b64;
document.body.appendChild(obj);

// Insert a link that allows the user to download the PDF file
var link = document.createElement('a');
link.innerHTML = 'Download PDF file';
link.download = 'file.pdf';
link.href = 'data:application/octet-stream;base64,' + b64;
document.body.appendChild(link);

I hope above code will be useful for you.
Thank you.

What is the programming language of this? Is this java/JS/groovy or some other language ?
How should be run this?

@Olivier-De-Groef ,

The script you are replying to, from four years ago, has nothing to do with Notepad++.

It appears it might be javascript intended to be run in the browser, but I wouldn’t run it without fully understanding the code. (I tried to base64-decode the string that the script supplied, for example, but it doesn’t end up starting with the bytes %PDF, so I am pretty sure it doesn’t decode into a PDF file like it purported to doing; as such, I really wouldn’t trust anything in that script.)

The right answer to the 2019 question is the one Alan gave in 2019: “you don’t”.

PDF is a binary format, not a text format, and Notepad++ is a text editor.
