An NGO in my locality provides visually impaired people with free newspapers in EPUB3 format. They use a software called Calibre to download the newspaper and convert it to EPUB, it then has to be converted to EPUB3. It is her they face difficulty, they have to do it manually and they don't have the adequate staff. Can this process be automated? Can EPUB files be converted to EPUB 3 automatically?
All suggestion and shared experiences are welcome.
