Is Loop video free? Is there a watermark?

Yes — Loop video is free to use with no sign-up or watermark. Very large files can still be limited by your browser's available memory and processing resources.

Do my files get uploaded to a server?

No. Loop video runs entirely in your browser with WebAssembly, so your MP4, MOV, WebM, MKV file never leaves your device and nothing is stored or seen by us.

What can I put in, and what do I get out?

Loop video accepts MP4, MOV, WebM, MKV and gives you back a MP4 file. You can also set total plays before you run it. Actual codec support depends on what the bundled engine or browser decoder can read.

Does Loop video change my original file?

No. It never touches your original — Loop video creates a brand-new MP4 file to download and leaves the source on your device untouched.

Get a better result

Best for: Repeating an already seamless clip two to four times into one continuous file without spending time on a new encode.
Input → output: The source streams are repeated and copied into an MP4 container for the selected number of plays. No crossfade or transition is added.
Quality tip: Start with an H.264/AAC MP4 whose first and last frames already connect. That is the safest combination for stream-copy muxing.
Know before running: WebM or MKV codecs may not fit an MP4 container cleanly, and mismatched timestamps can expose a seam. Copying streams preserves existing compression artifacts.
Next step: MP4 to GIF when the repeated motion needs to become a silent inline embed.

How to use Loop video

1
Choose your file. Drop a supported MP4, MOV, WebM, MKV file into the tool, or click to select one. It stays on your device — nothing is uploaded.
2
Pick your settings. Adjust the available options, then press Run. The first processing run loads the browser engine before conversion begins.
