LaBeam

Tool for converting PDF presentations to HTML for easier presenting.

LaBeam turns LaTeX Beamer PDFs into interactive HTML presentations — with a laser pointer, dark mode, table of contents, a full presenter view with notes, and real-time audience synchronisation. Core utilities are:

• labeam convert for converting a PDF presentation to a cross-plattform presentable HTML file, or
• labeam host for hosting a PDF presentation with presenter mode.

[!hint]

LaBeam stands for the initial missing laser beam in LaTeX Beamer presentations. Pun intended.
