Frequently Asked Questions

How many videos can I join at once?
There is no hard limit. You can add as many clips as you need. The only practical limit is your device's available memory and processing power.
Do the videos need to be the same resolution or format?
No. Our tool handles videos of different resolutions, frame rates, and formats. FFmpeg automatically re-encodes everything to a consistent output so the merged video plays smoothly.
Are my videos uploaded to a server?
No. All video processing happens locally in your browser using FFmpeg WebAssembly. Your files never leave your device at any point.
Can I reorder the clips before joining?
Yes. Simply drag and drop the clips in the list to arrange them in any order you want before joining. You can reorder as many times as needed.
Will joining reduce video quality?
Since clips may have different codecs or resolutions, a re-encode is needed to produce a consistent output. Choose CRF 18 for near-lossless quality. The visual difference at CRF 23 is virtually imperceptible for most content.
Does it work on mobile and tablet?
Yes. The joiner is fully responsive and works on Android and iOS. Open in Chrome, Safari, or Firefox — no app required.

Free Online Video Joiner — Merge Multiple Videos in Your Browser

Our online video joiner lets you combine any number of video clips into a single seamless file, processed entirely within your browser. Powered by FFmpeg WebAssembly, all merging happens locally on your device — no file uploads, no servers, and no compromise on privacy.

How to Merge Videos Without Quality Loss

Joining videos from different sources requires re-encoding to produce consistent output. Selecting CRF 18 in the quality settings delivers near-lossless results. The output will match or closely match the quality of your source clips while producing a single, smooth, gapless video file.

Merging Videos with Different Resolutions and Formats

Unlike some simpler tools, our joiner handles clips with different resolutions, frame rates, codecs, and container formats. FFmpeg normalizes all input clips during encoding so the final merged video has consistent playback from start to finish.

Why Browser-Based Video Joining is the Better Choice

Server-based video joiners require uploading potentially large files, waiting in a processing queue, and trusting a third party with your content. Browser-based processing eliminates all of that — your files stay on your device, processing starts immediately, and the result downloads in seconds.
