Loop Video Online
Processing entirely on your device — large files may take a moment.
Pick how many total plays you need and the clip is repeated into one continuous file with stream copy — packets are concatenated, not re-encoded, so the output is pixel-identical to the source and finishes in seconds.
Perfect for store displays, looping backgrounds, video walls and social clips that play on repeat — anything where the viewer should never see a cut.

About the MP4 format
MP4 (MPEG-4 Part 14) is the universal delivery container of digital video. It wraps H.264, HEVC or AV1 video with AAC audio, and its structure — separate metadata (moov) and media atoms — is what makes streaming, seeking and fast-start playback possible. Phones, cameras, TVs, browsers and every social platform assume MP4 first.
Quality is entirely a function of the codec and bitrate chosen at encode time, so an MP4 can be a 10 Mbps HEVC master or a postage stamp. That flexibility plus total playback coverage is why nothing has displaced it in twenty years — conversion between formats almost always ends in MP4.
+Strengths
- ✓Plays on every device and platform in existence
- ✓Streaming-ready structure (fast start, seeking)
- ✓Choice of modern codecs: H.264, HEVC, AV1
!Limitations
- −Quality depends entirely on encode settings
- −HEVC variants hit licensing gaps on some platforms
Frequently asked questions
Does looping reduce quality?
No. Stream copy concatenates the original packets — every repeat is a byte-exact copy of the source.
Why only up to 10 plays?
Longer loops are easy to get by running the tool twice on its own output — the cap keeps browser memory comfortable.
Will there be a visible jump at each repeat?
The join is as seamless as the clip itself — if the last frame matches the first, the loop reads as endless. A hard cut between different scenes will, of course, remain visible.
