@Ish-Modi it all depends on the pdf viewer you use, in the studio we use the standard pdf viewer which has the limitation I described.
in your app, you don't need to use the same pdf viewer, although it is handy to let the browser handle the preview, it will have the same limitation. instead, you can check other pdf viewers which allow this customization. I think pdf.js is one of those that don't have this problem and will let you have a download button with a custom name. another solution is to add to your app a custom download button that triggers download from jsreport-client.
