How it works

MOV to MP4 Converter for private browser workflows

Convert MOV to MP4 in your browser

Select a MOV file and get an MP4 output with broad compatibility across Windows, Android, web players, social platforms and editing software. The conversion runs entirely on your device.

Keep quality under control

Choose a quality preset or adjust resolution and bitrate manually. Higher quality preserves visual detail; lower settings produce smaller files for sharing and upload limits.

No upload, no queue

Unlike online converters that upload your video to a server, LessMB converts MOV files locally. Large and private recordings never leave your device.

Common use cases

Convert MOV clips from Apple devices to MP4 for Windows playback, presentations and uploads.

iPhone and Mac recordings

Make MOV files compatible with platforms that require MP4 uploads.

Social media

Create MP4 proxies from MOV sources for smoother editing on less powerful machines.
