How Can I Convert PDF to EPUB without Losing Format in Windows 11?

I have a large collection of PDF documents, and I've found that reading them on my e-reader can be challenging due to the format and layout. I think converting these files to ePub could make the reading experience much smoother and more flexible, as EPU is more responsive and easier to customize on most e-readers. However, I'm not sure what the best tools or methods are for making this conversion.

I've seen a few online PDF to EPUB converter tools, but I’m a bit cautious about using them because some of my files contain sensitive information. I’d prefer a reliable and secure offline method to convert PDF to EPUB without losing format if possible. Additionally, I’d appreciate any tips or recommendations on settings to ensure the layout, fonts, and images are preserved as much as possible in the ePub format.

Thanks for your reply!
