What is the Best YouTube Thumbnail Size?

YouTube recommends thumbnails at 1280×720 pixels (HD 720p, 16:9 aspect ratio) as the minimum. The highest quality available is maxresdefault at up to 1280×720 or higher for newer videos. ThumbGrab automatically detects and downloads the best available quality for any video.

How to Use the Video Info Tool

The Video Info tab fetches the real video title and channel name using YouTube's public oEmbed API — no API key required. You'll also see the video ID, all thumbnail URLs for every quality level, and a quick link to open the video on YouTube.
