Yes, absolutely. All video processing happens locally in your browser using JavaScript and WebAssembly. Your video files are never uploaded to any server. This ensures complete privacy and security of your data.
We support MP4, WebM, OGG natively, and HLS (m3u8), DASH (mpd) for streaming. For formats like MKV, AVI, and MOV, we use FFmpeg.wasm to transcode them in your browser for playback.

HLS was developed by Apple and uses .m3u8 playlist files. DASH (Dynamic Adaptive Streaming over HTTP) is an open standard using .mpd manifest files. Both provide adaptive bitrate streaming. HLS has better Apple device support, while DASH is more flexible and open.
