OnDevice is a free collection of online converters and utilities built around a single idea: you should not have to upload your files to a stranger's server just to convert them. Every tool on this site — file format converters, image editors, video converters and developer utilities — runs entirely inside your browser using JavaScript and WebAssembly. Your files are processed by your own device and never leave it.
Most online converters work by uploading your file to a server, converting it there, and letting you download the result. That model forces you to trust an unknown company with your documents, family photos and videos. Modern browsers are powerful enough to do this work themselves, so we moved the entire conversion pipeline to your machine. The result is a converter that is private by design: there is no upload step, no server-side storage, and no waiting in a queue behind other people's files.
OnDevice is built and maintained by DotandDash Technologies Pvt. Ltd. (dotanddash.in), a small independent software company. The site is free to use, with no account or signup required.
