A free, privacy-first document conversion utility — built for accuracy, speed, and simplicity.
Your files are never stored permanently. All uploaded documents and converted PDFs are automatically deleted from our servers within 10 minutes.
We use a server-side LibreOffice engine — the same engine trusted by millions — to ensure your converted PDF matches your Word document pixel for pixel.
Most conversions complete in under 5 seconds. Our LibreOffice daemon stays warm in memory so your first conversion is just as fast as subsequent ones.
Upload, convert, download — no sign-up, no email address, no personal information required. It's completely free, forever.
Whether you have an older .doc file, a modern .docx, or even a plain text document, DocToPDF handles them all — up to 50 MB in size.
DocToPDF runs on an AWS EC2 instance with HTTPS enforced via Let's Encrypt, UFW firewall, and regular security updates to keep your data safe in transit.
DocToPDF was created out of frustration with existing converters that either lose formatting, require a sign-up, charge a fee, or — worst of all — store your private documents on their servers indefinitely.
We believe that converting a file is a simple, everyday task that should be free and private. That's why DocToPDF uses a powerful LibreOffice engine running in headless mode on a dedicated server. There is no cloud storage, no third-party processing, and absolutely no human access to your files.
The service is hosted on a secure AWS EC2 instance, protected by HTTPS (Let's Encrypt SSL), a strict UFW firewall, and automated certificate renewal. We take uptime and security seriously so you can focus on your work.
DocToPDF is powered by Node.js on the backend with an Express HTTP server, LibreOffice for conversion, Nginx as a reverse proxy, and PM2 for process management. The frontend is pure HTML, CSS, and JavaScript — no heavy frameworks, which keeps the page load time under 1 second.
