Show HN: I built a tool to convert WhatsApp chats to PDF

1 gprogrammer1 0 8/20/2025, 8:55:20 PM chattopdf.app ↗
Hey HN! I built ChatToPDF to solve a problem I kept running into: needing to archive WhatsApp conversations for documentation, legal records, or just memories, but finding WhatsApp's export format terrible for sharing or long-term storage. What it does:

Converts WhatsApp's .txt export files into clean, readable PDFs Preserves the original chat formatting and timestamps

Why I built this: I needed to document some customer support conversations for my business, and WhatsApp's plain text export is basically unreadable for long chats. I wanted something that just works, respects privacy, and produces professional-looking output.
