how to decode base64 file to pdf file and output to separate page?

Answer 1

You have bytes in base64, right? so.
You decode, you get the file itself through new Blob() (for info in mdn or another dock)
You draw a link in the house, file the download attribute there - everything downloads fine, logically - you can give the PDF to the browser and it will view it, open it in a new tab. You can play with iframes. Dig in this direction. I did something similar recently, but in IE11 and below it didn’t want to work at all, I made it so that the browser directly receives a link to bytes from octet-stream and starts downloading itself.
