To convert PDF to ePub on Mac without errors, the key is using a stable PDF conversion tool that properly handles formatting, fonts, and images. First, install a Mac-compatible PDF converter such as SysInfo PDF Converter Tool (Mac version). After launching the software, add your PDF file using the Select File option. Once the file is loaded, choose ePub as the output format from the saving options. Select the destination folder where you want the converted file to be saved, then click Convert to start the process.
