About CommandPDF
CommandPDF is a free, privacy-focused PDF toolkit that runs entirely in your browser. With 99+ professional tools, you can edit, convert, merge, split, and secure your PDF files without ever uploading them to a server.
Our Mission
We believe that everyone should have access to powerful PDF tools without compromising their privacy or paying expensive subscription fees. That's why we created CommandPDF – a comprehensive PDF toolkit that puts your privacy first.
Unlike traditional PDF services that require you to upload your files to remote servers, CommandPDF processes everything locally in your browser. Your sensitive documents never leave your device, giving you complete control over your data.
Whether you're a student, professional, or casual user, CommandPDF provides all the tools you need to work with PDFs efficiently and securely.
Project and documentation
CommandPDF builds on open-source PDF software, including PDF.js, pdf-lib, MuPDF and LibreOffice. BentoPDF provided inspiration and reference logic; CommandPDF adds a Next.js interface and a visual workflow editor.
Our guides should describe the controls in this application, explain limitations, and distinguish examples from measured results. The practice walkthrough includes synthetic files so you can check the result yourself.
