ChatMark — ChatGPT Export to Markdown, PDF & PNG

Select prompts and answers from private ChatGPT chats, then export Markdown, PDF or PNG locally—no tracking or conversation uploads.

Save the useful parts of a ChatGPT conversation—not the surrounding interface. ChatMark lets you select prompts and answers, then export editable Markdown, a searchable PDF, or PNG images for sharing directly in your browser. Choose exactly what belongs in your file. Keep the full conversation, remove irrelevant turns, or select assistant answers only with one click. How to use: 1. Install ChatMark and open a private conversation on chatgpt.com. 2. Click Export conversation in the toolbar at the top of the conversation. 3. Select the prompts and answers you want to keep. 4. Choose Markdown, PDF, or PNG and download your file. Markdown keeps the conversation editable and can also be copied to your clipboard. PDF keeps its clear layout and selectable text, with A4 and Letter output. PNG creates a clean, 960 px wide image of your selected messages for sharing. It defaults to Computer preview; in Account and settings, you can choose Fewer images instead. Long conversations split between complete question/reply pairs, keeping each pair and its attachments together. An unusually long pair may produce a tall image. A single image downloads as PNG; multiple images download in one ZIP file.
