Kiunganishi cha Video bila malipo
Unganisha klipu kadhaa za video kuwa MP4 moja kwa mpangilio unaochagua. Ukubwa tofauti hutoshelezwa kwa mikanda myeusi; klipu zinazolingana huunganishwa bila kusimbua upya. Inafanya kazi ndani ya kivinjari chako — bila kupakia.

Faili zako hazitoki kwenye kifaa chako kamwe. Uchakataji wote unafanyika ndani ya kivinjari chako.
Jinsi Inavyofanya Kazi
Joins several video clips into one MP4, in the order you choose, with the FFmpeg engine running in your browser. Clips of different sizes or shapes are fitted into one frame with black bars instead of being stretched or cropped.
- 1Add and order your clipsDrop in MP4, MOV, WebM or MKV files, then drag them or use the up/down arrows to set the order. Tap a thumbnail to preview a clip.
- 2Each clip is checkedFFmpeg (WebAssembly, ~31 MB, downloaded once and cached) reads every clip's codec, frame size, frame rate and audio format. Nothing is uploaded.
- 3Matching clips are joined as-isWhen every clip shares the same codec, size, frame rate and audio (e.g. several clips from one phone), they are joined by stream copy with FFmpeg's concat demuxer — no re-encoding and no quality loss.
- 4Mixed clips are re-encoded to one frameOtherwise each clip is scaled to fit the output size (same as the first clip, 1080p or 720p), padded with black bars, set to one frame rate and encoded to H.264 with AAC audio. Clips without sound get silence so the audio stays in sync.
Your videos are read directly from your device by the in-browser engine and the merged MP4 is built in memory. No clip is ever uploaded to a server.
