Video Stitcher
Combine multiple clips into one continuous video, in your browser.offline
Works fully offline once this page is loaded — no upload, no server. Decoding depends on your browser's
built-in codec support (mp4/h264 and webm are the safest bets; obscure formats like AVI/WMV may not load).
Export comes out as one WebM file (or MP4 if your browser's recorder supports it) —
that's the format browsers can natively record to without a bundled encoder library.
