常见问题解答

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.
