Frequently Asked Questions
What email formats are supported?
Email Converter supports MBOX, EML, and PST formats. You can convert between any combination — import from one format and export to another.
How do I convert my email files?
Simply drag and drop your email files onto the app window, select the output format, and click Convert. The converted files will be saved to your chosen destination folder.
Is there a maximum file size limit?
There is no hard file size limit. Email Converter is a native macOS app and can handle large mailbox archives with thousands of emails. Performance depends on your Mac's available memory and disk space.
Does the app work offline?
Yes. All email processing happens entirely on your Mac. No internet connection is required to convert files. Your emails never leave your computer.
