POST /api/v1/md has accepted unauthenticated requests since May, and the VS Code and Obsidian extensions have shipped on that path from day one. The page on this site was the odd one out: it redirected you to a sign-in form before you could even see it.
It doesn't any more. Open Markdown to PDF, paste your Markdown or drop a .md file, pick a page size and theme, and convert. Same terms as the API and the extensions: up to 20 pages per document, a small watermark, per-IP rate limits, and nothing kept afterwards.
The output is unchanged, because it was never a different pipeline. Real heading structure, alt text on figures, table headers and reading order, dual-compliant by construction (PDF/A-2A + PDF/UA-1). Tables, syntax-highlighted code blocks, task lists, Mermaid diagrams, LaTeX math and GFM alerts all come through.
Create a free account and the 20-page cap comes off, your renders are listed for re-download under Settings, Renders for 7 days, and you can insert images from your asset library. The watermark stays on Free and Hobbyist and comes off on Starter and above; pricing has the full breakdown.
