Endnotes to parenthetical notes

A simple online converter that takes an EPUB file with endnotes or footnotes and produces a new EPUB in which all of those references are pulled directly into the main text as parenthetical notes. Instead of navigating back and forth between the text and the end of the book to read citations like “[1]” or “[2],” this tool embeds the note content inline, making it easier to read on devices without touchscreens or convenient navigation controls
