常见问题
关于 Grab 的常见问题解答。
Is this YouTube video downloader free?
Yes. You can download videos, audio, and thumbnails without paying or creating an account.
What formats can I download?
You can grab MP4 and WebM video, M4A and WebM audio, and high-resolution JPG thumbnails.
Do I need to install anything?
No. Grab runs entirely in your browser. Just paste the YouTube link and choose the format.
Is it legal to download YouTube videos?
You should only download content you have the right to use. Respect copyright and the creator's terms. This tool is intended for personal, permitted content.
Why is there a CDN fallback?
YouTube uses streaming protections that can block direct downloads. The CDN fallback helps you still get your file when the direct route isn't available.
