OpenAI Data Exporter

A developer released a free, local browser tool called OpenAI Data Exporter that converts chats from OpenAI's data export ZIP into Markdown and PDF files, including full-size embedded images when available. The tool runs entirely in the browser with no backend, account, or telemetry, and works offline, optionally fetching web-linked images when online.

A completely free, local and private browser tool that extracts your chats from the OpenAI Data Export ZIP as MD and PDF files, including full-size embedded images when available. I made this because the official OpenAI data export is fine as a backup, but not great if you actually want to use your conversation history. The tool extracts each chat as a separate MD or PDF file, or both, and saves available original images and attachments to an Assets folder. It handles individual chats or bulk exports, large archives, selectable PDF text, and optional chat creation/update dates in filenames. 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. 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 is completely free. I wanted a better way to keep, search, reference and reuse my own ChatGPT history, and figured it might be useful to others too. Cheers
