I am looking for a reliable solution to convert a large number of emails from MBOX files to PDF format. Specifically, I have more than 1000 emails, and I want to process them in batches to save time. I have come across some tools that claim to support batch MBOX to PDF conversion, but I am unsure which one is safe, accurate, and preserves all email content (like attachments, headers, and formatting). Could anyone share their experience or recommend a trusted tool that can handle this?
