MBOX vs Thunderbird Conversion: Which Tool Works Best?

I have several years' worth of email data stored in MBOX format, and I also use Mozilla Thunderbird for managing my emails. Now I need to convert these mailboxes into other formats like PST, EML, PDF, or HTML for backup, legal compliance, and migration to another email client. I tried some manual methods, but they are time-consuming and often lead to issues such as missing attachments, broken folder structure, or data loss. Since MBOX and Thunderbird store emails differently, I am confused about which conversion tool works best and ensures accuracy, data integrity, and ease of use. Can anyone suggest a reliable solution for MBOX vs Thunderbird conversion that works efficiently even for large mailboxes?

Both tools are best for conversion purposes. If we talk about Thunderbird Converter, it converts a bulk Thunderbird mailbox at once to multiple formats. But on the other hand, MBOX Converter also converts single or multiple MBOX files at once. And DataVare MBOX Converter is one of the best tools. It supports 20+ mbox-supported email clients such as Thunderbird, Mac Mail, SeaMonkey, PocoMail, etc. And many more features that makes it advanced software. So if we compare MBOX vs Thunderbird Converter...i prefer MBOX Converter always.
