Turn a PDF into a responsive web page

Every page becomes a section of flowing paragraphs with an optional custom title. Text reflows to any viewport — unlike the fixed PDF layout.

Safe for reports going online

Pages rebuild as flowing responsive sections locally, so annual reports, manuals and newsletters never pass through a server.
