Prepare a clean Markdown source
Use headings, paragraphs, ordered or unordered lists, block quotes, fenced code, horizontal rules, and simple pipe tables. Keep the Markdown source because it remains the editable and searchable version.
- Use UTF-8 text.
- Break very long content into readable paragraphs.
- Represent images with useful alt text; remote image files are not fetched.
Choose the page settings
Select A4 or US Letter, a narrow, normal, or wide margin, and an optional document title. The preview is a safe structural view rather than the final PDF page bitmap.
Generate and verify the PDF
The browser paints bounded pages, embeds them as PNG images in a PDF, and reopens the generated bytes to verify page structure before enabling download.
Understand the output limits
PDF text is not selectable or searchable because each page is an image. Complex Markdown extensions, custom fonts, inline images, and exact typography are not reproduced, and Unicode appearance depends on fonts available in the browser.
Keep document contents private
The source, canvas pages, and PDF remain in current-tab memory. No link or image destination is fetched, and closing the tab releases the working state.
