The downloader is designed for Android, iPhone, tablets and desktop browsers without requiring an app or account.
Download YouTube Thumbnail in HD, 1080p & More
When you download a YouTube thumbnail, the available resolution depends on the image version YouTube has generated for that video. ThumbGrab checks several common variants, including the maximum available image and standard, high-quality, medium and default versions.
| Option | What it means | Best use |
|---|---|---|
| Maximum available | Highest thumbnail variant we can retrieve | Design reference and archiving |
| Standard HD | Higher-quality fallback | Web and social use |
| High Quality | Compact high-quality version | Quick sharing |
| Medium / Default | Smaller thumbnail variants | Previews and lightweight pages |
Important: “4K thumbnail” is often used as a search phrase, but YouTube may not provide a true 3840×2160 thumbnail for a particular video. ThumbGrab downloads the highest available source rather than creating an artificial 4K image.
