The browser creates a temporary file and saves it where you choose.
Pliego does not have
The PDF is not sent or stored.
The document and output live in tab memory. Resetting, replacing, or closing discards the job and revokes temporary URLs. We use cookieless Cloudflare Web Analytics for aggregated navigation and performance statistics. We do not send your PDF, its name, content, page count, or document metadata to analytics. Navigation and performance requests are separate from the document's local processing.
Hosting can still see
Normal web requests.
To serve HTML, CSS, JavaScript, favicon, and worker, the host processes IP, headers, and logs under its platform terms. Vercel previews may inject its toolbar. Those requests do not contain the selected PDF.
