  • Batch and playlist downloads: save multiple files or entire playlists at once.
  • Conversion and trimming: built-in converters, audio extraction, or basic editing.
  • Speed & reliability: download speed, handling of site changes, and uptime.
  • Privacy & safety: whether the tool collects data, displays ads, or bundles unwanted software.
  • Cost & licensing: free, freemium, subscription, or one-time purchase.
  • Ease of use: UI simplicity, documentation, and support.
