Cobalt is for people who want to save media from supported websites for offline viewing, listening, or reuse. Paste a link to download available videos, audio, photos, or GIFs without installing a separate desktop app or browser extension. What you can save depends on the source site and content. For video, you can choose an available quality and, for YouTube downloads, select a preferred format and codec. For audio, Cobalt can save the original format when possible or convert it to options such as MP3, OGG, WAV, or Opus. It also includes a local remux tool for changing a media file’s container without re-encoding it. Cobalt’s official-instance privacy policy says it does not store identifiable information about users; some download requests require encrypted processing data that is deleted after 90 seconds. Use it only for content you have permission to download.
