Merge Videos Online

Merging videos online has never been simpler. Upload your video clips by dragging them onto the page or clicking to browse your files. The tool accepts MP4, MOV, and WebM files up to 200MB each, with a maximum of 10 clips per merge. Each uploaded clip appears as a thumbnail card showing its duration, resolution, and file size.

Arrange your clips in the desired order by dragging the cards left or right. Choose between a hard cut (instant transition) or crossfade (smooth dissolve) between clips. Select your preferred output format and resolution, then click Merge Videos. The combined video is ready to download in seconds to minutes depending on total duration and whether re-encoding is needed.

Desktop video editors like Adobe Premiere or Final Cut Pro are powerful but excessive for simply joining clips together. They require installation, often need paid licenses, and have steep learning curves. Server-based merging tools require uploading potentially large and sensitive video files to third-party infrastructure, consuming bandwidth and raising privacy concerns.

This browser-based approach gives you the best of both worlds. FFmpeg — the same engine powering professional video workflows — runs directly in your browser via WebAssembly. Your videos are processed entirely on your device with zero network transmission. For the common task of combining a few clips into one file, this is faster and more private than any alternative.
