About this tool

About Video Converter

Convert video formats online

Use Video Converter to convert between MP4, MOV, AVI, MKV, WebM, MPEG and M4V. Every supported video format can also produce an MP3 audio file, while MP4 and WebM clips can be turned into animated GIFs.

Control quality and output size

Choose a smaller, balanced or high-quality result. Resolution controls can preserve the original dimensions or limit output to 1080p, 720p or 480p, while frame-rate settings help reduce motion data when a compact result matters more than maximum smoothness.

Private browser-based processing

The converter uses a local WebAssembly media engine, so supported files stay on your device. Video conversion is demanding: close unused tabs for large clips, keep the original file, and preview the downloaded result before replacing your source.

Frequently asked questions

Video Converter FAQ

Which video formats can I convert?

MP4, MOV, AVI, MKV, WebM, MPEG and M4V can be converted to one another or to MP3. MP4 and WebM can also be converted to animated GIF.

Are my videos uploaded?

Supported conversions run locally in your browser. Your selected video is not uploaded by zer.ai for processing.

Why can video conversion take longer than image conversion?

Video contains many frames plus audio, so transcoding uses substantially more processor time and memory. Duration, resolution, codec and output quality all affect speed.
