Frequently Asked Questions
Which video platforms are supported?
Supported platforms depend on the current implementation. Paste a video URL and the tool will attempt to extract downloadable formats. Platform support may change as sites update their APIs.
What video formats can I download?
Available formats vary by source video. Common options include MP4 (video+audio combined), separate video and audio streams, and different quality levels from 360p to 1080p or higher when available.
Is downloading videos legal?
Downloading copyrighted content without permission may violate terms of service and copyright law in your jurisdiction. Only download videos you have the right to save - your own content, Creative Commons licensed material, or content where the platform explicitly allows downloads.
Why might a download fail?
Common reasons: the video is private or age-restricted, the platform changed its API, the URL format is not recognized, or the video is live/streaming-only. Try a different quality or format option.
Are downloads processed on a server?
Video extraction requires server-side processing to resolve URLs and stream content. Dokall processes requests through its API. Do not use this tool for private or sensitive content.
