Questions fréquentes

Quick answers.

Is my video uploaded to your servers?

No. The compression process runs entirely within your browser using your device's local processing power.

Which video formats are supported?

Most modern formats including `MP4`, `WebM`, and `MOV` are supported, though compatibility depends on your specific browser's encoding capabilities.

How does the quality slider work?

Lowering the quality increases the compression ratio, resulting in a smaller file size but more visible artefacts in the footage.

Will the audio quality be affected?

The compressor primarily targets the video bitrate to save space, but audio is usually re-encoded at a standard efficient bitrate to maintain balance.
