Show HN: CLI tool to transfer your chats from Telegram to WhatsApp

Tired of your Telegram logs sitting vulnerable in cloud exports? This Node.js CLI tool lets you seamlessly import your Telegram chat history (JSON + media) into WhatsApp Web—with rate limiting, pause/replay support, and smart error handling. It preserves original timestamps and sender info, and resumes cleanly if interrupted .

Why it matters: Telegram’s cloud chats lack true end-to-end encryption—your entire history is stored on their servers and potentially exposed. WhatsApp, on the other hand, offers robust E2E protection, keeping all your conversations private, on-device only. Finally you can back-up your chats to a channel that actually secures them.

Use it like this: 1. Login — scan QR code once, stay authenticated. 2. List — pick the target WhatsApp chat (DM or group). 3. Plan — parse your Telegram export, validate messages and media, generate an import plan. 4. Execute — start the import with configurable delay between message to avoid blocking by WhatsSapp, resume support, and media validation.

Set it up quickly (Node 18+ required):

``` git clone git@github.com:rafaelsales/transfer-telegram-to-whatsapp.git npm install telegram-to-whatsapp login telegram-to-whatsapp plan path/to/telegram-export/ telegram-to-whatsapp execute path/to/output/ --target-chat "123456789@g.us" ```

The tool handles progress tracking, retries, idempotency (stop/resume), authentication caching, and gracefully skips problematic media—perfect for long or interrupted imports.

In short: it’s a no-frills way to move away from an insecure cloud-stored archive and reinstate your chat in a strongly encrypted channel. Open source (MIT), cross-platform, and reliable.
