Picknar is a web tool for creators, designers and writers who need thumbnail images from YouTube videos and Shorts. Pasting a YouTube URL shows a full-width preview of every available resolution, requesting maxresdefault.jpg first and falling back to hqdefault and sddefault when the 1920x1080 file does not exist. Shorts URLs are detected automatically in their vertical format. Each preview offers a download or a Copy Thumbnail URL button that returns the direct i.ytimg.com link for use in Notion, Slack or blog posts. Bulk mode handles up to 15 links, with JPG, PNG or WebP export. It is free, with no login and no watermark.
