What is the fastest Way to convert large PDF files to ePub?

The fastest way to convert large PDF files to ePub is to use a reliable desktop converter instead of online tools. Large PDFs often exceed upload limits on web-based platforms and may crash during processing.

A tool like SysInfo PDF Converter Tool allows you to add large or multiple PDF files at once and select ePub as the output format. Since it works offline, the conversion speed mainly depends on your system performance, not internet speed. It also helps maintain formatting, images, and text structure during conversion.
