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
