Your files stay on your device

Bulk YouTube thumbnail downloader

Paste up to 25 YouTube links or ids and get the largest thumbnail each video actually has, grey placeholders dropped, zipped with a CSV manifest.

One per line, or separated by commas or spaces. Watch, youtu.be, Shorts, embed, live URLs, and bare 11-character ids mix freely.

The probe checks YouTube's public thumbnail files on i.ytimg.com in size order, from maxresdefault down to default, and drops the sizes that do not exist plus the grey 120x90 placeholder YouTube serves instead. No YouTube API key is used, and only thumbnail image bytes leave your browser: the links you paste ride the image requests. Titles load through YouTube's oEmbed endpoint when it allows the request; otherwise rows show the video id. Download only thumbnails you own or have permission to use.
