Key features of this tool
Lossless loop
The streams are copied, not re-encoded, so quality is identical and the job takes seconds.
Original format kept
MP4 stays MP4, WebM stays WebM, MOV stays MOV.
FFmpeg in your browser
The real FFmpeg, compiled to WebAssembly and loaded on first use (about 30 MB, then cached); files are processed locally and never uploaded.
Frequently asked questions
Why is there a small jump at the loop point?
The video simply restarts; for a seamless loop the clip itself must start and end on matching frames.
Is there a length limit?
The source can be up to 150 MB; ten repeats of a large file produce a large output that must fit in browser memory.
Why is the first use slow?
FFmpeg (about 30 MB) is downloaded the first time and cached; after that it starts in a second or two. Encoding itself runs on one CPU core, so long videos take a while.
Are my files or data uploaded?
