# Free Video Converter

Convert video files for free. In-browser client-side video conversion with full data privacy.

## What is Video Converter?

The Video Converter changes a video’s format so it plays on the device or platform you need. It accepts MP4, MOV, WebM and AVI files and converts them to MP4 (H.264 video with AAC audio — the most compatible format for phones, TVs and social media) or WebM (VP8 with Vorbis audio for the web). Conversion runs on ffmpeg compiled to WebAssembly in your browser, so your footage is never uploaded. The video engine (about 31 MB) is downloaded once and cached.

## How to use Video Converter

1. Choose an MP4, MOV, WebM or AVI video.
2. Select MP4 (H.264) or WebM (VP8) as the output.
3. Convert and download the new video.

## Frequently asked questions

### Which output format should I pick?

MP4 (H.264/AAC) plays almost everywhere — iPhone, Android, Windows, TVs, WhatsApp and social networks. Choose WebM only for web pages that specifically need it.

### How long does conversion take?

It depends on your device and the video length. Browser-based encoding is slower than desktop software, so short clips (a few minutes) work best.

### Is my video kept private?

Yes. Decoding and encoding run in your browser; nothing is uploaded.
