Overview
We need a Web based platform that can automatically convert input documents in Word (.docx) or PDF (.pdf) format to professional-looking ebooks in EPUB (.epub) format. The input documents may contain only text or text and images.

IMPORTANT: A SIMPLE CONVERSION IS NOT ENOUGH
There are already several Third-Party software/packages that can perform a simple conversion from Word / PDF to EPUB. Such a conversion will just convert the Word / PDF file to an EPUB file with the usual changes such as:
Reflowable content instead of page by the page content, minor changes in placement of text and images, and so on. This alone is not enough. Instead, the final EPUB document should look like:
- A professionally designed ebook with an appropriate layout, margin, spacing, font, color, placement of text and images, and so on.
The platform should allow our uploaders who are usually authors/writers who can write good content but may not be proficient in designing and formatting an ebook. So our platform should allow them to upload the input document with minimal or poor formatting.
The platform most not only not simply convert the input document to a corresponding EPUB document but must modify the layout, placement, etc. so that the final document will be a professionally designed ebook. The final document must be in standard .epub format that can be read on any of the popular EPUB readers available today.

API – The platform must have a section called API plugin so that any site the sell Ebook can plugin to our website to receive converted Epub format document automatically.
The section must be developed as an API that will accept a Word or PDF file as input and produce the EPUB file as output. The API must have secure authentication and authorization features to prevent public users from accessing it.
