ChatGPT export formats compared — Markdown, PDF, and PNG
Choose a ChatGPT export format for editable notes, searchable documents, or shareable images.
Choose a format for what you will do next
The right format depends on how you plan to use the saved conversation. Choose Markdown for editing, PDF for reading and printing, or PNG for sharing a visual excerpt.
| Goal | Format | What you get | ChatMark access |
|---|---|---|---|
| Write notes, revise text, reuse code | Markdown | Editable text with formatting syntax | Always free |
| Keep a document, search text, print | Searchable, selectable text with paper settings | Shared trial with PNG, then Pro | |
| Share in chats or add to slides | PNG | Fixed-width images, split for long conversations | Shared trial with PDF, then Pro |
Export Markdown for free
Use Copy MD to paste Markdown source into an editor, or Download MD to keep a .md file. Both options are free without usage limits or a ChatMark account. This is a useful starting point when you want to keep improving the saved material.
See the ChatGPT to Markdown tutorial for the steps, code and table previews, and image-link limitations.
Save a searchable PDF
Choose PDF for consistent page dimensions and printing. ChatMark supports A4 and Letter, with searchable and selectable text. PDF works well as a reading document; save Markdown first if you expect to substantially rewrite the content.
See the ChatGPT to PDF tutorial for paper sizes, themes, and checks after downloading.
Export PNG images
PNG is useful for sharing visual content directly. Images are 960 pixels wide and support light, dark, or Follow ChatGPT themes. Long conversations split between complete question/reply pairs; one image downloads as PNG, and multiple images arrive in a ZIP. PNG does not offer PDF-style text search or selection.
See the ChatGPT to PNG tutorial for image splitting, long-image previews, and extracting the download.
Limits shared by all three formats
ChatMark reads the current private conversation branch and lets you select prompts, answers, or individual messages. Shared links, bulk export of multiple conversations, and exporting every branch are not supported. Save important original images and attachments separately; an exported document does not guarantee complete media archiving.
PDF and PNG share one 72-hour extension trial without a payment method. It does not automatically become a paid subscription. Continued access to those formats requires a linked Pro account; Markdown remains free. See current plans.
