Format Guide β Which to Choose?
MP4
Best overall compatibility. Works on all devices, browsers, and players. Recommended for sharing and web use.
MKV
Open format, supports multiple audio/subtitle tracks. Great for high-quality video storage and archiving.
MOV
Apple's format. Best for macOS, iOS, and Final Cut Pro workflows. High quality, larger file size.
WebM
Google's web format. Smallest file size for web embedding. Supported by Chrome, Firefox, and Edge.
GIF
Animated image format. No audio, limited colors, large file size. Best for short clips under 10 seconds.
How It Works
This converter uses FFmpeg.wasm β a WebAssembly port of the industry-standard FFmpeg library compiled to run entirely in your browser. Your video files are never uploaded to any server. All processing happens locally on your device. The FFmpeg WASM binary (~30MB) is downloaded once from a CDN and cached by your browser.
