Loop Video Maker
Turn a still image and an audio file into a looping MP4 — match the audio or fill 1, 3 or 8 hours. Runs in your browser; nothing is uploaded.

Add an image and an audio file to begin.
Longer videos are heavy — 3 and 8 hours can take a while and a lot of memory, so a desktop is strongly recommended. The first render downloads the video engine (~25 MB) once.
How to use
- Add a still image and an audio file using the two boxes.
- Choose the length — match your audio once, or loop it to fill 1, 3 or 8 hours.
- Press Make video, wait while it renders, then download your MP4.
FAQ
Is the video made on your servers?
No. The video is built right in your browser using ffmpeg compiled to WebAssembly. Your image and audio never leave your device. The first time you make a video, the engine (about 25 MB) downloads once and is then cached.
How long does it take?
Short videos that match your audio are quick. Multi-hour loops are heavy — they can take several minutes and a lot of memory, so a desktop is strongly recommended. On a phone, stick to “match the audio” or 1 hour.
Which files can I use, and what do I get?
Image: PNG, JPG or WebP. Audio: MP3, WAV, M4A or OGG. The result is an MP4 (H.264 video + AAC audio) that plays on YouTube, social media, and every modern device.
