About Video Merger
OptiPix Video Merger combines 2-10 video files into a single video directly in your browser. Upload videos, reorder them, and merge with automatic format handling. Uses FFmpeg.wasm concat demuxer for fast merging when formats match, or re-encodes for mixed formats. All processing local.
How It Works
FFmpeg.wasm concat demuxer joins videos. Same-format files use -c copy for lossless merging; mixed formats re-encode to H.264+AAC.
