Hi HN! I built https://chattopdf.app after losing important WhatsApp conversations when switching phones. The problem: WhatsApp's built-in export creates messy .txt files that are hard to read and share professionally. Whether it's business conversations, family memories, or legal documentation, there's no clean way to archive chats. What it does:

Converts WhatsApp exported chats into clean, formatted PDFs Preserves timestamps, sender names, and message flow Handles media placeholders and emoji properly Works with both individual and group chats
