About iTextMaster
iTextMaster is a professional, privacy-focused PDF toolkit. With 106 tools, you can edit, convert, merge, split, and secure PDF files; most file tools run locally in your browser, and server-side tools disclose processing clearly.
Our Mission
We believe that everyone should have access to powerful PDF tools without compromising their privacy. That's why we created iTextMaster – a comprehensive PDF toolkit that puts your privacy first.
Unlike traditional PDF services that upload every task to remote servers, iTextMaster is local-first. Most file tools process in your browser, while server-side tools clearly disclose what is submitted.
Whether you're a student, professional, or casual user, iTextMaster provides all the tools you need to work with PDFs efficiently and securely.
Our Values
Privacy First
Most file tools keep your documents on your device. Server-side tools disclose their processing path before you submit data.
Fast & Efficient
Powered by modern web technologies, iTextMaster delivers fast PDF processing locally for most file tools, with clear server disclosure when a tool needs backend rendering.
Accessible Everywhere
Available in 11 languages and works on any device with a modern browser. No installation required.
Start Free
Browser-local PDF tools are free with no usage limits. Sign in when you need API Keys and API Credits; server-side website tools may apply fair-use limits.
Open Source
Built with transparency in mind. Our code is open source, allowing anyone to verify our privacy claims.
Community Driven
Developed with feedback from users around the world. We continuously improve based on your needs.
Built with Modern Technology
iTextMaster is built using cutting-edge web technologies to ensure the best possible experience:
