FlipSnack is a simple web-based tool that allows users to turn a PDF file into a magazine style document. Signing up for an account is required and it does require authentication within 15 days, but you don't have to do that to upload and create a Flip Book. To add a file you can upload it, drag and drop, or add it through a URL. Each document is limited to 500 pages (If I ever have something that long, it will be published, not uploaded here though!)
If students are working on a project, this would be a great way to prepare it and share it with teachers and students. It can easily be embedded to a blog or website as well. When you create your flip book you have the option of four different styles. You can choose the size, background color, etc. The premium version allows download and embedding without a watermark. You can see a sample of one of my PDF's below.
