[shuvashish76]

Feature request for something similar to what File Commander offers.

•	File Commander incorporates a file conversion** service which allows you to convert from more than 1200 different file formats
•	Work with virtually all available file formats such as: PDF, DOCX, XLSX, EPUB, MOBI, HTML, TXT, GIF, JPG, FLAC, MP3, MP4, M4A CSV, BMP, PPTX, TIFF, and many more

File conversion:
File Commander upload your files to their cloud 1st then convert & download it. I believe uploading personal files to cloud for whatever reason isn't good for our privacy.

These two apps build on ffmpeg to convert audio & video files OFFLINE.

Another app which converts pdf to epub OFFLINE using some iText library.

What about combining all these file conversion features to a single app? Currently no such all in 1 opensource app. (we can't compete File Commander which supports 1200 different formats but this is a good start IG)
It'll increase the size obviously as OFFLINE based. Probably not for AFU.
This could be a complete new Amaze plugin app.
