Why Choose Our Video Merger

Browser-Based

FFmpeg runs as WebAssembly directly in the browser tab. Your clips never leave your machine, and there is no waiting for a server to process them remotely.

Seamless Joining

Add up to 10 clips, drag them into the order you want, and the merged video plays them in exactly that sequence with no gaps between segments.

Quality Preserved

FFmpeg re-encodes all clips to a consistent H.264/MP4 output. The output resolution and frame rate match the first clip, and audio from every segment is carried through in sequence.

Multiple Formats

Input clips can be MP4, WebM, or MOV. You can mix formats in the same merge job and the tool will handle the re-encoding. The output is always an MP4 file.

Perfect For

Social Media Compilations YouTube Videos Event Highlights Video Montages Presentations Travel Vlogs Demo Reels Music Mashups

Powered by FFmpeg.wasm

FFmpeg.wasm

FFmpeg.wasm is a full port of the FFmpeg video processing library compiled to WebAssembly. When you click Merge, the browser runs FFmpeg locally rather than sending your files to any remote server. The same FFmpeg engine that powers professional desktop video tools handles the concatenation.

Because clips may have different codecs or frame rates, the merger always re-encodes to H.264 video and AAC audio in an MP4 container. This guarantees a compatible output regardless of what formats you mixed in the input.

Frequently Asked Questions

Upload two or more video clips, drag them into the order you want, and click Merge. FFmpeg WebAssembly runs in your browser tab and combines all clips into one continuous MP4 file. No server uploads are involved.

Yes. The merger re-encodes everything to a single format, so mixing MP4, WebM, and MOV in the same job works fine. For the cleanest output, use clips with the same resolution and frame rate. If they differ, the output will use the first clip's resolution as the baseline.

Up to 10 clips per merge job. For longer projects, merge your first batch, download the result, then upload that merged file as the starting clip for the next batch.

Each individual file can be up to 500MB. Since processing happens in your browser, total combined size under 200MB is recommended for smooth performance. Larger files may work but will take longer to process.

Completely. FFmpeg WebAssembly runs locally, so none of your source clips are transmitted anywhere. The merged output file is saved to your account so you can download it again later if needed.

Short clips under 30 seconds each usually finish in under a minute. Longer clips or many clips together may take a few minutes since FFmpeg is doing full re-encoding locally. A real-time progress bar shows the percentage complete.

Yes. Drag any clip in the list to a new position before clicking Merge. The final video plays the clips in exactly the order shown in the list at the time you merge.

Input clips can be MP4, WebM, or MOV. The output is always MP4 with H.264 video and AAC audio, which plays on virtually every device, browser, and platform.

Yes. Each clip's audio track is concatenated in the same order as the video. The audio from clip 1 plays during clip 1, clip 2's audio during clip 2, and so on through to the end of the merged file.

Nothing to install. The tool runs in any modern desktop browser. The first time you use it the browser loads the FFmpeg.wasm library, which may take a few seconds, but after that it is available immediately.
