  • All popular formats — the video converter reads MOV, MKV, WebM, AVI, M4V, MPG and other common video files and writes MP4, WebM, MOV, MKV or AVI

How to Convert a Video to MP4 Online

  1. Upload your video file or paste a direct link to it.
  2. Choose the output format — MP4 for compatibility everywhere, WebM for websites.
  3. Press “Convert video”: the file is converted on our servers in seconds.
  4. Download the result or find it later in your archive.

MP4 or WebM: Which Format Should You Choose?

MP4 with the H.264 codec is the safe default. It plays on every phone, smart TV, browser and editor, messengers show it inline, and social platforms accept it without extra processing — which is why most people who look for a video converter simply need an MP4 converter. Choose WebM when the video lives on a website: it compresses a little better at the same quality and browsers play it natively. MOV, MKV and AVI outputs are there for editing software and media players that expect a specific container. If you only ever need one direction, we also have dedicated MOV to MP4, MKV to MP4, WebM to MP4 and AVI to MP4 converters, plus a video to GIF tool.

When You Need to Change Video Format

  • A file that will not open — an old recording or a camera clip in an unusual container starts playing everywhere once you convert the video to MP4
  • Uploading to a platform — sites and messengers accept MP4 far more reliably than exotic formats, so a quick conversion saves a failed upload
  • Editing on another device — convert video files into the container your editor or phone gallery understands before you start cutting
  • Publishing on the web — WebM keeps pages light, and this online video converter prepares it in one step

Frequently Asked Questions

Is this video converter free?

Yes. New users get starter energy points, and one conversion costs only 2–5 points depending on the length of the video, so you can convert several files right away.

Which video formats can I convert?

The converter reads MOV, MKV, WebM, AVI, M4V, MPG and most other common formats, and saves the result as MP4, WebM, MOV, MKV or AVI.

Does converting reduce video quality?

When the source codec already matches the target container, the stream is copied without re-encoding and quality is untouched. Otherwise we re-encode at a high bitrate.

Will there be a watermark on the converted video?

No. The file is returned without any watermark, in the original resolution.

What is the maximum file size?

Up to 700 MB and 60 minutes when the video inside is H.264 and the target is MP4, MOV or MKV — that is a container repackage, not a re-encode (with Prime: 1 GB and 3 hours). Anything that needs real re-encoding is limited to 200 MB and 5 minutes.
