How it works
1

Export from Signal

In Signal Desktop, go to Settings → Chats → Export chat history to generate your .jsonl file.

2

Load your file

Select your .jsonl backup file in the converter. Nothing is uploaded — it stays on your machine.

3

Filter & format

Choose date ranges, add case numbers or labels, and select what to include before generating.

4

Generate your PDF

Click generate. The process runs locally in your browser and usually completes in under a minute.

Who it's for

Documentation & Records

Preserve co-parenting logs, business agreements, or workplace communications in a structured, timestamped format.

Personal Archiving

Keep a permanent, readable record of conversations with loved ones — saved as PDF, a format that's been around for 30 years and isn't going anywhere.

Platform Migration

Save your full history in a universal format before switching devices or Signal accounts.

Flexible filtering

  • Select specific date ranges or use presets — Last 30 Days, This Year, etc.
  • Keyword search to find specific messages before generating
  • Export only what you need, nothing more
