I’m working on some flash books, and some PDF files were converted to flippingbooks. And then an idea comes across me: why not convert all those PDFs to one flippingbook? I think this is a good idea, which I don’t have to store dozens of files in a document.

Yes, so we provided this feature.
First, click “batch convert” button to open the batch convert window.
And then check “merge all PDF files to one” option shows in below image. All selected files will output as one flash book file.
