Thats Great Its Working. Thanks a lot. Can we specify the path where the file is to be downloaded?? EhsaanIsrar we cannot. Browsers normally use the user settings for downloaded files. EhsaanIsrar you can mark the answer as accepted though, can you not? I'm not sure what do you mean by 'automatically in xhtml'. The question was about javascript which should work just fine. You can add a script tag at the end of the body etc — minj.

You seem to be confusing something. Anonymous , 15 december at Need to convert base64 to pdf and need to have handle of the pages for customization. Ghanshyam , 23 february at This is a very helpful code that you provided here and thanks for it.

I have a question related to my implementation. I want to show a pdf file into Salesforce using base64 data in the JS. I referred to this code and it works fine when I run at other places or playgrounds. But, when I try to run the same code in the Salesforce platform after making some platform-related changes in the code then it throws this error.

Could you please help me if you can? Can we set object-src or any other attribute while creating the object dynamically in the JavaScript?

To solve this problem, your server must return the correct Content-Security-Policy HTTP header that is, it must allow the data: scheme. However, please keep in mind that this opens doors to potential XSS attacks so make sure you understand all the risks. Lalit , 28 april at Hi, How can we convert multiple base64 string data to a single pdf?

For example, if I have an array of base64 string and I want to make a single pdf then how can I do that. Avinash , 27 may at Hi Guru, Your code is working like jum, but a small question, instead of downloading the pdf i want it be opened. How can we achieve this. Please suggest.
