Can I import my PDF into StoryJumper?

You can convert your PDF to .jpg files (using tools like the following: https://smallpdf.com/pdf-to-jpg) and then upload each .jpg file to StoryJumper and make them into "Scenes".

 

If you use another application to create your PDF, you'll want to design your pages in "landscape" format so the page width is about 1.35 times bigger than page height.
