And one more thing - It's TOTALLY FREE!
Download and read your PDF file for FREE without conversion.
Use your favourite file manager to open your PDF file. Wait until your file will be converted. Usually it takes few minutes. After that you can easily read them. App automatically saves your converted books, so you don't need to convert them again while opening your document.
Some PDF files are scanned documents. They don't have texts, only images. In this case this app cannot convert them to texts.
