Make a clip play forward then backward on repeat, like a boomerang, without an app
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.A boomerang plays a moment forward and then backward, over and over: a jump that lands and un-lands, a glass that fills and empties. Choose a video, mark up to 10 seconds of it, and pick how many forward-and-back cycles you want. Your browser draws each frame in order and encodes a new MP4, so nothing is uploaded. Boomerangs are silent, as played backward sound rarely works.

A short clip often needs to run longer: a background loop for a stream, an hour of rain for sleep, a product shot on a shop screen, or a dance move to practise. Loop Video puts the same clip end to end as many times as you need.
No quality lost. The repeat modes copy every compressed frame exactly as it is in the file, with the sound, the way Join Videos does. Nothing is decoded or encoded again, so a 4K clip stays 4K and a long loop takes seconds rather than minutes.
Boomerang. Boomerang plays a part of the clip, up to 10 seconds, forward and then backward, as many as 10 times. Those frames do not exist in that order in any file, so this mode draws each one and encodes a new H.264 MP4, without sound. It takes longer and is a fresh encoding, at up to 1920 pixels on the long side and 30 frames a second. Reverse uses the same drawing to play up to 60 seconds backward once.
The rest of the article, and all 6 questions about Loop Video, are on the Loop Video page.
Drop the clip on Loop Video, keep Repeat selected and choose how many times, from 2 to 100. The page shows the final length and size before you start. Press Loop the video and Download the MP4; every frame and the sound are copied, so it looks and sounds exactly like the original.
Not in the Repeat and Length modes: the compressed frames are copied untouched into one MP4, the way a file is copied, so there is no second generation of compression. Only Boomerang encodes again, because it has to show frames in an order the file does not hold.
Choose Boomerang, mark up to 10 seconds with the start and end boxes, and choose how many forward-and-back cycles you want. Press Make the boomerang; your browser draws every frame and encodes a new H.264 MP4. Boomerangs are silent, as most sound is unpleasant played backward.
Repeating by copying needs to read the frames inside the file, and the copy engine here reads MP4, MOV and M4V. A WebM, or any other format your browser can play, still works for Boomerang, which draws frames from the browser's own player. Convert the file to MP4 first to repeat it.
