# Open, convert & certify WhatsApp chats — no upload

> Open an exported WhatsApp chat, read it back with media in place, search and filter it, export it as a PDF, and package it with SHA-256 hashes and a draft certificate — all in your browser, nothing uploaded.

Chat Desk reads exported chats entirely on your device. Nothing is uploaded, nothing is written to browser storage, and the transcript, the PDF, and the evidence pack are all produced in this tab.

## Tools in this workspace

- [Chat Viewer](https://www.safepaper.app/chat/chat-viewer): Open an exported WhatsApp chat — the .txt or the media .zip — and read it back as a real conversation with photos, voice notes, and documents in place. Search it, filter by sender or date, and jump anywhere in the thread. The export is read in your browser and never uploaded.
- [Chat to PDF](https://www.safepaper.app/chat/whatsapp-chat-to-pdf): Turn an exported WhatsApp chat into a clean PDF with selectable text. Choose chat bubbles, a plain document, or a numbered transcript, include or drop the images, and export the whole thread or just the part you selected — converted entirely on your device.
- [Evidence Pack](https://www.safepaper.app/chat/chat-evidence-pack): Package an exported WhatsApp chat for a lawyer, an HR case, or a court filing: SHA-256 of the original export, per-attachment hashes, Bates numbering, a cover page recording how the file was handled, and a draft certificate under section 63(4) of the Bharatiya Sakshya Adhiniyam. Built in your browser, so the original never leaves your device.
- [Chat Analyzer](https://www.safepaper.app/chat/chat-analyzer): See who talks most, when the conversation runs hot, how quickly people reply, and which days went quiet. Works on an exported WhatsApp chat of any size and counts everything locally — no account, no upload, no analytics on your conversation.

Each tool also has a Markdown mirror at its URL plus `.md` (for example https://www.safepaper.app/chat/chat-viewer.md).
