よくある質問 (FAQ)

How much smaller will my video get?

It depends on the preset and your source video, but the "Recommended" preset typically cuts file size by 50-80% with little visible quality loss.

Is there a file size limit?

Videos up to 300MB are supported. Everything is compressed locally in your browser, so larger files just take longer to process.

What output format do I get?

The compressed video is always exported as MP4 (H.264 + AAC audio), the most widely compatible format for sharing and playback.
