ChatGPT workflow
Markdown keeps document structure visible. That makes long prompts easier to cut down, headings easier to preserve, and excerpts easier to inspect before they become model input.
Best when you want a human-editable working copy rather than a raw PDF dump.
A strong default flow
The point is not just conversion. It is giving yourself a better review surface before the conversation starts.
Keep enough structure that section breaks, lists, and major headings remain obvious during prompt editing.
Use cleanup controls to remove repeated margin text, repair line wraps, and fix words broken across lines.
Paste only the sections that matter rather than handing the model the entire document when a few pages would do.
Quick answers
Use Markdown when section structure matters and plain text when you want the simplest, flattest export possible.
Often yes. Cleaner exports mean fewer irrelevant tokens and less layout junk competing for space in the context window.
Use Auto or OCR mode. PDF2X can run OCR locally, then you can still export the result as Markdown if that is the better working format for your prompt.
