How to use YouTube thumbnail
Paste any youtu.be or youtube.com watch URL. Omnipus reads the video ID and loads the official thumbnail sizes. Download the largest one that exists (some older videos lack maxres). Do not reuse someone else’s thumbnail as your own clickbait.
Paste a public URL
Copy a public link you have the right to save and paste it into the tool.
Fetch media
Our server requests that public URL (or a public extraction service for some sites) so your browser can list downloadable media. We do not archive it.
Save a copy
When media is available, preview it and download. Respect the creator’s rights and the platform’s terms.
About this tool
Paste a YouTube URL or video ID and download maxres, HQ, or MQ thumbnails. Thumbnails are public images served by YouTube — handy for moodboards, critiques, and your own channel assets.
