Comment 6 for bug 1653673

The PDF import option 'Import via Poppler' (aka 'Poppler/Cairo import' in upcoming Inkscape 0.92) is not available via command-line in Inkscape (related feature request: bug #1507740) - on Linux, you can use the standalone binary 'pdftocairo' installed with the poppler library instead (it does the same as Inkscape's 'Import via Poppler' option). The command-line tool 'pdftocairo' is not part of Inkscape, and likely not easily available for Inkscape users on Windows.

Note that the poppler/cairo-based PDF->SVG conversion does not keep text as editable text content: glyphs are outlined as paths, and inserted as clones (<use> references) for recurring instances of the same characters.
