I have a large number of PDF files that I need to convert into different formats, mainly JPG, PNG, and HTML. Doing them one by one is taking a lot of time, and some online converters I tried either limit the number of files or require uploading sensitive documents. 

I’m looking for a reliable way to convert multiple PDFs at once without compromising the original formatting or quality. Ideally, I want a desktop solution that supports batch conversion and works offline. I came across BitRecover PDF Converter, which seems to support multiple output formats and bulk conversion. Has anyone used it, and how well does it handle large PDF collections?
