Hello all attachments are forcibly downloaded.
If you want to simply link to a pdf document you can link it in your editor.

Yes i know that is simply but i need to make it with attachment to open directly if there is any solution i can modified any file

Unfortunately this is not possible since you would have to change the header for each file type.
