Frequently Asked Questions

Is it safe to convert WebM to M4V online?

Absolutely! Our video converter runs entirely in your browser using WebAssembly. Your video files never leave your device - they're processed locally for complete privacy and security.

What's the maximum file size I can convert?

You can convert video files up to 1GB in size. Since processing happens in your browser, larger files may take longer and use more system resources.

Will I lose video quality when converting to M4V?

M4V uses efficient compression. Our converter offers quality presets to help you balance file size with visual quality. The 'High Quality' setting preserves excellent video quality.

How long does video conversion take?

Conversion time depends on your device's processing power and the video's size/length. The first conversion downloads the video processor (~25MB), but subsequent conversions are much faster. Expect 1-3x the video's duration for processing time.

What video codecs are supported?

Our converter supports modern codecs like H.264, VP9, and AAC audio. This covers the vast majority of video files including MP4, AVI, MOV, WebM, and other popular formats.
