About PureConverter
A revolutionary media conversion tool focused on privacy, running entirely inside your web browser.
Absolute Privacy
Traditional online converters require uploading files to their servers, where they are saved and processed. In PureConverter, files never leave your machine. Processing is local.
No Server Limits
Forget queues or file size limits (like the 100MB caps imposed by other tools). The only limitation is the processing power and RAM of your own computer.
WebAssembly Powered
We use native WebAssembly (WASM) builds of FFmpeg (for audio/video) and ImageMagick (for images), allowing high-performance binary code to run directly inside the browser's JavaScript engine.
Offline Ready
Once the page loads and the WASM binary assets are in your browser cache, you can convert files even if your internet disconnects, as all the work is done offline.
Gregorium Labs
PureConverter is proudly developed and maintained under the Gregorium Labs initiative, a personal project focused on building technology systems, tools, and useful utilities.
For this specific project, we adopted a 100% client-side (in-browser) architecture to ensure maximum privacy, allowing the conversion to run completely offline after the initial load, with no need for server intermediaries for your files.
