Is it free to convert WebM to MP4?

Yes, VideoConvert offers free WebM to MP4 conversion. The free tier supports MP4 output at up to 720p. Pro users get all formats, 4K resolution, batch conversion, and no watermark for a one-time $29 payment.

Does converting WebM to MP4 lose quality?

VideoConvert uses FFmpeg with configurable quality presets. The High preset (CRF 18) produces output that is visually indistinguishable from the source. You control the quality-to-size tradeoff with four presets: High, Medium, Low, and Draft.

Do I need to upload my video to a server?

No. VideoConvert processes everything locally on your computer. Your video files never leave your device, ensuring complete privacy and eliminating upload wait times.

How long does WebM to MP4 conversion take?

Conversion speed depends on file size, resolution, and your computer's hardware. A typical 1080p video converts in seconds to a few minutes. Local processing is often faster than cloud services because there is no upload or download step.
