Convert GIF to BMP free and local
Transform your GIF files to BMP instantly. GIF is the iconic 8-bit limited color loop animation format, ideal for low-weight fast animations. On the other hand, BMP is the native Windows bitmap format, uncompressed, characterized by its absolute compatibility but large file sizes. 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.
