Convert JPEG to WEBP free and local
Transform your JPEG files to WEBP instantly. JPEG (Joint Photographic Experts Group) is the universal compressed photographic standard ideal for storing real-world images in a reduced space. On the other hand, WebP is the modern image format by Google designed to optimize weight on the web, offering superior lossless and lossy compression compared to PNG and JPG. All processing is performed locally, ensuring your file never travels 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 web for fast tasks. Download the App for heavy duty.
The browser is great for quick, daily tasks like optimizing a PNG, formatting code in a pinch, or compiling a fast PDF. But if you need to convert gigabytes of video, transcode entire folders of music, or compress giant files, the Nua Convert desktop app takes full advantage of every core of your processor, without the memory limits imposed by Chrome or Firefox tabs.
