Because of that, I decided to build something that works better for my own archive.</p> <p>OpenAI Data Exporter is a standalone HTML tool that extracts each chat as a separate MD or PDF file, or both, and saves available original images and attachments to an Assets folder.</p> <p>PDF export was one of the main reasons I built it. When the original images are available in the data export, the PDFs use full-size embedded images instead of the tiny thumbnails you usually get.</p> <p>It handles individual chats or bulk exports, large archives, selectable PDF text, and optional chat creation/update dates in filenames.</p> <p>Everything runs locally in your browser. Your chats are not uploaded anywhere. There is no backend, account, telemetry or analytics. It works offline; when you're online, web-linked images can optionally be fetched and embedded in PDFs.</p> <p>It's completely free. I built it for my own archive and figured it might be useful to others too.</p> <p>OpenAI Data Exporter on GitHub:<br> <a href="https://github.com/zivanovicmarko-stack/OpenAI-Data-Exporter" rel="noopener noreferrer">https://github.com/zivanovicmarko-stack/OpenAI-Data-Exporter</a></p> showdev ai chatgpt productivity
