How it works
Add a video, set the start and end, choose the format and how the picture fits, then press Download. The new MP4 is made on your device; nothing is uploaded.
Are my files uploaded anywhere?
No. Everything is processed by your own browser. Your music is not sent to our server or anyone else, so the tool is private and works even with very large files.
