100% local file conversion
Your files stay with you. Simple as that.
Hi! Welcome to Nua Convert. A clean space where you can optimize your images, format code, and convert structured data instantly. Everything is processed directly on your computer. Fast, ultra-secure, and without your files ever traveling across the internet.
Local-First Philosophy
Your files stay at home. By pure architecture.
I designed Nua Convert with a very simple golden rule: the best way to protect your files is to never have them. That's why all processing is executed 100% in your browser using modern JavaScript, Canvas, and WebAssembly APIs.
The server only sends you the web page to load. Once you're inside, you can disconnect from the internet if you feel like it: the workspace will continue to function perfectly locally. No tricks, no catches, no strings attached.
Web vs Desktop
Use the web for the quick tasks. Download the App for the heavy lifting.
The browser is great for everyday tasks like optimizing a PNG, formatting code in a pinch, or compiling a quick PDF. But if you need to convert gigabytes of video, transcode entire music folders, or compress giant files, the Nua Convert desktop app leverages every core of your processor to the max, without the memory limits imposed by Chrome or Firefox tabs.
