Frequently asked questions
No, the video ID is extracted entirely in your browser and thumbnails are loaded directly from YouTube's own public image servers — nothing passes through or is stored on VN Tools' side.
The 1280×720 maxresdefault thumbnail only exists for videos uploaded in HD; for older or lower-resolution uploads, YouTube may not have generated that size, so the tool automatically hides unavailable sizes.
Thumbnail images are typically owned by the video's uploader or YouTube — check the specific video's usage rights before using its thumbnail commercially, especially for videos you don't own.
