About ToolKhoj
ToolKhoj ("Khoj" meaning discovery or search in Hindi) was engineered to fix a broken paradigm on the internet: why should you have to upload your sensitive PDFs, invoices, and family photos to a mysterious third-party server just to compress, merge, or convert them?
Modern web browsers have extraordinary computing power. With WebAssembly, HTML5 Canvas, Web Workers, and modern JavaScript engines, virtually all standard file manipulation can be performed safely on your local device.
