Markdown to PDF,
without a watermark

It is easy to assume a watermark is a faint logo you can live with. The damage usually goes further than the appearance of the page, because of how the mark is added.

• Watermark text is normally drawn into the same text layer as your content, so selecting a paragraph and copying it can pick up the vendor's name mid-sentence
• That stray text is indexed too — searching the PDF, or a document system that indexes it, matches on words you never wrote
• Screen readers read the mark out loud, often once per page
• A semi-transparent stamp interacts badly with print: what is barely visible on a backlit screen frequently comes out solid grey on paper
• It cannot be removed after the fact without converting the document again somewhere else, so the file has to be regenerated rather than fixed

The watermark is rarely there to protect anything. It is the upsell: the free tier has to be good enough to prove the tool works and annoying enough that anyone using the document for real has a reason to pay. That is a reasonable way to run a business, but it means the free output is designed not to be usable, which is a poor deal if you simply want a PDF of a README.

Not every watermark is obvious, and some are placed where you are unlikely to look. Three checks take a few seconds each.

• Open the PDF, select all and paste into a text editor — any vendor name or URL that appears was in the text layer, not in your Markdown
• Use the reader's search for the tool's name, and for words like "trial", "demo" and "created with"
• Check the last page and the page margins, not just the first page — footer bands and corner marks are common and easy to miss

Nothing. No mark, no footer credit, no metadata naming this site as the producer beyond what any browser engine writes, and no page cap that quietly truncates a long document. Page numbers are the only thing this tool adds on its own, they are genuinely optional, and the switch is in the style panel.
