Hi @G-Rom, glad to hear you got it to work on Chrome! I am not an Apple user, so can’t test Safari here. Perhaps @Jon can take a look as to whether downloading files from n8n is a general problem in Safari when he has a bit of time?
Can you confirm what version of n8n you are using? I have just given it a go and the PDF downloaded had data in it and the correct file size reported in the n8n interface.
