Use Google Search for "convert PDF to HTML." See page after page of links which Google might monetize alongside the paid advertisements it already has.
Google makes it look like this is a difficult task, not a solved problem with a FOSS solution - Pdftohtml that ships in many Linux distros.
Google obfuscates the most relevant information by burying it within links to discussions on Linux forums. Even though there's a fucking SourceForge page and it links to a Windows friendly version. The crap results increases the odds that the average user will click through a revenue generating link either directly on Google's page or on a site running their ads.
