Base64 representing PDF to blob - JavaScript

Question

I have a Base64 string representing a PDF file. I want to convert it to a file with the Blob object using javascript. After it\'s done i want to save the blob as a PDF file

Answer 1

You have to convert the base64 string back into the original binary data. Using atob is not sufficient, you'll have to run it through a loop and convert it to an array buffer - Convert base64 string to ArrayBuffer
Then use that to create the blob.
