To batch convert EPUB to PDF files, you can use a converter that supports multiple file processing at the same time. Instead of converting each EPUB file individually, tools like SysInfo EPUB Converter allow you to add several EPUB files or an entire folder at once. After launching the software, you can choose the Select Folder option to upload multiple EPUB files. Then select PDF as the output format and start the conversion. The tool processes all the files together and generates separate PDF documents for each EPUB file in the chosen destination folder.
