Home / Highlight paragraphs - EPUB Files


is it possible? I’ve been looking at the options but haven’t found anything, when I try to highlight paragraphs in a pdf file it works well but with EPUBs it doesn’t work

this photo represents what i mean


Highlights are appended to PDF as defined by PDF Standard, however there is no similar function for appending highlights into ePub in MuPDF.

SumatraPDF older pre-release versions prior to 3.2 version had such an experimental highlighting feature and you can still write your own .smx for use with 3.2 portable, see Annotate (highlight / add comments) with SumatraPDF - #7 by GitHubRulesOK

Note that trial feature is unlikely to be revived as coding conflicted with PDF highlights, so for now that’s as good as it can be / was.
