Frequently asked questions

Is this MP4 converter really free?

Yes, completely. No fees, no subscription, no watermark and no sign-up: you don’t need to create an account or log in to convert your videos to MP4.

Are my videos kept private?

Yes. The conversion to MP4 happens on your device whenever possible: the video is not uploaded. If your browser can’t handle it (AVI, WMV, GIF, very large file…), it is sent over an encrypted connection (HTTPS), converted in a temporary folder and deleted immediately. We keep no copy, nobody watches your videos, and they are never shared or reused.

Which formats can I convert to MP4?

All common video formats are supported: MOV, AVI, MKV, WebM, WMV, FLV, M4V and MP4, as well as GIF and APNG animations. The maximum size is 1 GB per file.

Why convert a video to MP4?

MP4 is the most compatible video format: it plays on every phone, computer, TV and browser, and it is accepted by social networks, messaging apps and video platforms. Our MP4 files are also optimized to start playing instantly when streamed online.

Does converting to MP4 reduce quality?

The video is re-encoded to H.264 with a good-quality setting, and the audio to AAC at 128 kbps: for most videos, the difference from the original is hard to see.

Can I convert a GIF to MP4?

Yes. Just upload your GIF: it is turned into an MP4 video, often much lighter and smoother to share than the original animation.

Can I convert an iPhone video to MP4 on my phone?

Yes. The converter runs in the browser on iPhone, Android, tablets, Mac, Windows and Linux: you can turn an iPhone MOV video into MP4 without installing an app.
