How does video looping work?

This tool uses FFmpeg.wasm's concat demuxer to join the same video file N times using stream copy — no re-encoding, so it's fast and lossless. The output is a single MP4 file.

What is the maximum number of loops?

You can choose between 2 and 20 repetitions. Keep in mind the output file will be roughly N times the size of your original video.

Is my video uploaded to a server?

No. All processing is done inside your browser using FFmpeg.wasm. Your files never leave your device.

Frequently Asked Questions

Are my videos uploaded to a server?

No. All looping is done using FFmpeg.wasm which runs entirely in your browser. Your video files never leave your device and are never transmitted to any server.

How many times can I loop a video?

You can loop a video from 2 up to 20 times. The output will be a single continuous video file with the content repeated the specified number of times.

Can I loop an MP4 online without uploading it?

Yes. Choose an MP4 file, set the repeat count, and export a single looped video directly in your browser. Your video stays on your device and is not uploaded to a server.

Will quality be lost when looping?

No. Stream copy mode is used to concatenate the loops without re-encoding, so the original video and audio quality is fully preserved throughout all repetitions.
