What PDF2flip is
PDF2flip is a free, open-source web application that displays PDFs as page-turning digital books. You can open a document stored on your computer or use one hosted online. During reading, you can create notes and export them afterward. To share a PDF that starts on your computer, it must first be uploaded to a public direct file link; Nuage via Apps Éducation is one example. URL parameters can direct a reader to a particular page, show one page at a time, limit the book to a page, or hide the controls. When a PDF cannot be reached directly because of CORS restrictions, PDF2flip uses a CORS proxy automatically. If you control the PDF server, the project recommends enabling access with CORS headers. The application is based on Paginis and uses the lite version of the dflip library. It is distributed under the GPL, which requires modified redistributed versions to use the same license. The project welcomes feature suggestions, bug reports, and development discussion through tickets or email. Its free plan is listed as free, with no specific usage limits stated.
