Choose the conversation and format
Open the conversation in ChatGPT and open ChatShell from its page control or the Chrome extension toolbar. Complete any first-use prompts, choose Current Chat, and select PDF. Review the available settings and document title. Enable image export if the images are part of what you need to keep.
Create and open the file
Select Export and save the result. ChatShell generates the PDF with its local engine; it may download fonts needed for rendering. Very long conversations may be split into PDF parts in a ZIP, so open the archive and check each part.
Review the pages
Compare the first and last messages with ChatGPT. Inspect long code lines, wide tables, formulas, and images. Check page breaks around headings. Keep important uploaded attachments separately if they are not present in the export.
If the document includes sensitive content, inspect it before sending it and check the sharing permissions of the destination folder. Generating a PDF locally does not control what happens when you upload or email it.
Know the alternatives and limits
A browser’s Print command may be enough for a quick page snapshot, but its output depends on what the page has loaded and its print layout. Always check the preview and saved file.
ChatShell PDF export is for a single conversation. Pro batch export offers HTML, Markdown, DOCX, and JSON, not PDF. If you need to revise the text before producing a final document, start with DOCX or Markdown.
