About Video to MP4
MP4 is the video type that plays on every phone, TV, computer and website. If a video will not open, will not upload, or will not send, changing it to MP4 usually fixes the problem. This tool converts your video to MP4 without adding a watermark.
Which videos can I convert?
MOV (iPhone and Mac), WEBM (screen recordings), MKV, AVI, FLV, 3GP, M4V and WMV. When the video inside is already MP4-friendly, the tool just repacks it, which takes only seconds and keeps full quality.
Is it private?
Everything happens inside your own browser. Your file is never uploaded to our server, so nobody else can see it.
How long does it take?
Repacking takes seconds. A full conversion uses your own device, so allow roughly one to three times the length of the video. A computer is faster than a phone for long videos.
Questions people ask
Will my MP4 have a watermark?
No. There is never a watermark, and the tool is free.
Is there a file size limit?
Videos up to about 1 GB work well on a computer. Phones have less memory, so very large videos may stop partway. If that happens, try on a computer.
Can I convert a YouTube link to MP4?
No. This tool converts video files you already own. Downloading from YouTube or other platforms breaks their rules.
Does quality get worse?
If the video only needs repacking, quality stays exactly the same. A full conversion keeps quality very close to the original.
