How this tool works
Nothing here writes a PDF. Your text is laid out as a formatted page, that page opens in a new tab, and your browser's own print dialogue appears — choosing "Save as PDF" as the destination is what produces the file. That is a deliberate choice: browsers make clean, text-based PDFs with selectable text and embedded fonts, and using one avoids shipping a large PDF library for a job it already does well.
The title becomes a heading on page one and is offered as the suggested filename. The body is treated as plain text with its line breaks preserved, so paragraph structure survives a paste, but there is no styling: no bold, no headings inside the body, no lists, no images and no tables. Nothing is uploaded and nothing downloads on its own.
Getting the settings right
- Turn off headers and footers: browsers stamp the page title, the URL, the date and a page number onto every sheet by default. A footer reading about:blank is not the impression you were going for.
- Check the paper size: the dialogue follows your system locale, which is A4 in most of the world and US Letter in North America. A document built for one loses an edge on the other.
- Narrow the margins if it helps: the default is generous, and a document running to five pages often fits four at a tighter setting without looking cramped.
- Allow pop-ups if nothing happens: the page is opened in a new tab, and a blocker will stop it silently. Permit pop-ups for this site and run it again.
