OpenAI Data Exporter - A local MD and PDF exporter with full-size embedded images

A developer built OpenAI Data Exporter, a standalone HTML tool that converts OpenAI chat history into local MD or PDF files with full-size embedded images. The tool runs entirely in the browser, works offline, and does not upload any data, addressing limitations of the official OpenAI data export for archival purposes.

The official OpenAI data export is fine as a backup, but not great if you actually want to use your conversation history. Because of that, I decided to build something that works better for my own archive. 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. 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. It handles individual chats or bulk exports, large archives, selectable PDF text, and optional chat creation/update dates in filenames. 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. It's completely free. I built it for my own archive and figured it might be useful to others too.
