Which YouTube links does it accept?
The box accepts a bare 11-character video ID or a link in any of the common forms: youtube.com/watch?v=, youtu.be short links, and /shorts/, /embed/, /live/ or /v/ paths, including the m.youtube.com mobile site. Extra parameters such as a start time are ignored. A video opened from a playlist works because its link still carries v=. Playlist, channel and @handle links have no video ID, and the tool shows "Could not find a YouTube video ID." The preview cards appear as soon as the box holds a valid ID.
For youtu.be/dQw4w9WgXcQ?t=42 the tool reads the ID dQw4w9WgXcQ and builds image addresses such as i.ytimg.com/vi/dQw4w9WgXcQ/maxresdefault.jpg. Your browser loads the images straight from i.ytimg.com, YouTube's image server, and Download saves that one as youtube-dQw4w9WgXcQ-maxresdefault.jpg. OneClickUse's own server is not involved.
Why does the High thumbnail have black bars?
The tool offers five of the standard files YouTube keeps for each video: Max Resolution (maxresdefault, usually 1280×720), Standard (sddefault, 640×480), High (hqdefault, 480×360), Medium (mqdefault, 320×180) and Small (default, 120×90). Standard, High and Small are 4:3 frames, so a widescreen video sits inside them with black bars. In the 480×360 file the picture is 480×270 with 45-pixel bars above and below; in the 640×480 file the bars are 60 pixels each.
The preview cards crop every image to 16:9, which hides those bars until you open the downloaded file. For a clean widescreen picture, use Max Resolution or Medium. If only High exists, crop 45 pixels from its top and bottom in any image editor to get a 480×270 frame without bars (60 pixels each for the 640×480 Standard file).
What does the Download button check?
Download fetches the file, checks the reply and saves the JPG exactly as YouTube serves it, without resizing or re-compressing it. If YouTube has no file at that size, you see "This thumbnail size is not available for the video." and nothing is saved, so try the next size down. Open shows the same address in a new tab, where your browser's own save option also works.
To make your own 1280×720 thumbnail with a title and subtitle over a background image, use the YouTube Thumbnail Generator. The YouTube Tags Extractor shows a video's title, description and tags next to its thumbnail.
