What it is
TronoPDF is a free online PDF toolkit with over 38 tools for merging, splitting, compressing, converting, editing, signing and securing PDF files, plus image editing capabilities. Unlike traditional server-based PDF tools, most TronoPDF tools process files directly in your browser, keeping your documents on your device. The service requires no signup, no account, and offers unlimited use of all features at no cost.
The toolkit includes tools for organizing PDFs, converting between formats like PDF to Word, PDF to PowerPoint, PDF to Excel, and vice versa. It also offers PDF security features including password protection and encryption, as well as image tools for compression, resizing, and conversion. For supported tools, all processing happens locally in your browser using technologies like Web Workers and open-source libraries, ensuring your files never leave your device.
