AAC encoding (in browsers without a built-in AAC encoder) by [FFmpeg's libavcodec](https://ffmpeg.org/) ([LGPL-2.1-or-later](https://ffmpeg.org/legal.html)), loaded as a separate file only when needed.

No. The clips are read, joined and encoded inside your browser tab and are never sent to a server. The page only downloads its own code from dragbin.com, plus an AAC audio encoder from dragbin.com if your browser doesn't have one built in. ### Does merging re-encode my videos? Usually, yes. Each clip is decoded and encoded again as H.264 video with AAC sound at the size, frame rate and quality you choose, which takes a while and loses a little quality. When every clip has exactly the same video format, size and encoder settings, for example several clips from the same phone or camera, a fast option appears that copies the video untouched. The sound is still re-encoded in that mode so every clip fits one audio track. ### What happens when the clips have different sizes or frame rates? The merged video uses the first clip's size, or 1080p or 720p in the first clip's shape. Every other clip is scaled to fit inside that frame without cropping or stretching, so a clip with a different shape, such as a portrait phone video in a landscape merge, gets black bars. The frame rate is the first clip's (up to 60 fps) or 30 fps; clips at other rates have frames repeated or skipped to match. Sound is converted to 48 kHz stereo, and a clip with no sound becomes silence for its length. ### How many clips and how much video can I merge? From 2 to 20 clips, up to 15 minutes in total on a computer and 5 minutes on a phone or tablet. Each file can be up to 2 GB on a computer and 500 MB on a phone or tablet. The limits exist because the sound track and the finished video are held in your device's memory until you download it. ### Which files and browsers work? MP4, MOV, MKV and WebM clips work, as long as your browser can decode their video, and the result is always an MP4. You need current Chrome, Edge or Firefox on a computer, or Safari 16.4 or later. Firefox for Android can't process video. Safari before version 26 can't decode audio, so sound from your clips can't be kept there and the merged video would be silent; the clip list tells you before you merge.
