Why use this PDF to LaTeX converter

Every equation as LaTeX

Inline and display maths are recognised across the whole PDF, not one formula at a time.

Text around the maths

Section headings, paragraphs and tables come with it, so you keep the context.

Pandoc-friendly

The Markdown uses standard $ and $$ delimiters, so pandoc -f markdown -t latex turns it into a LaTeX body.
