常见问题
Quick answers.
›Are my video files uploaded to your server?
No. The clipping process happens entirely within your browser's memory. Your original video never leaves your computer.
›Does trimming reduce the video quality?
By default, the tool performs a stream copy which preserves the original bit rate and resolution. Quality only changes if you choose to re-encode the output to a different format.
›Which video formats are supported?
The trimmer supports common web-compatible containers including `MP4`, `WebM`, and `MOV`. Compatibility depends on your browser's native codec support.
›Can I trim videos for social media?
Yes. You can set precise start and end points to meet the duration requirements for platforms like Instagram, TikTok, or X.
