No. ThumbGrab collects zero personal data. Your browser communicates directly with YouTube's public APIs and CDN — we never intercept or store this data. Recent search history is saved only in your browser's local storage and never sent to our servers. You can delete this anytime via browser settings. See our Privacy Policy for complete details.
Not every YouTube video has a 4K (maxresdefault) thumbnail. This depends on the video resolution at upload and what the creator explicitly set during publishing. If 4K isn't available, ThumbGrab automatically falls back to the next best quality (usually HD 720p or SD 480p). Newer videos and higher-resolution uploads are most likely to have 4K thumbnails available.
No. ThumbGrab is an independent tool developed and maintained by VexLab Technologies. We are not affiliated with, endorsed by, or connected to YouTube LLC, Google LLC, or Alphabet Inc. in any way. ThumbGrab simply provides convenient browser-based access to publicly available thumbnail URLs from YouTube's public CDN. "YouTube" is a registered trademark of Google LLC.
