How It Works
No signup. No watermarks. Just a perfect YouTube thumbnail preview in seconds.
Click the upload zone and select your image. The tool supports JPG, PNG, WebP and GIF formats.
Enter your video title, channel name, view count, upload date, duration and subscriber count.
Optionally add title text on your thumbnail with full font, size, color, shadow and position controls.
Enable NEW, LIVE, HD, CC, 4K badges and set the duration badge position on your thumbnail.
Instantly switch between Home Feed, Search Results, Watch Page, Mobile, and Shorts previews.
Upload a second thumbnail for A/B comparison, then download a PNG screenshot of any view.
A great thumbnail can double your click-through rate — but most creators upload blind, only seeing how it looks after publishing. Our free YouTube thumbnail preview tool lets you test your thumbnail in every context before you upload a single file to YouTube.
Preview your thumbnail in the Home Feed grid, Search Results list, Watch Page player and sidebar, YouTube Mobile app, Shorts feed, and A/B side-by-side comparison mode. Toggle between dark and light YouTube themes, add text overlays, test badge placements, and simulate watch progress bars.
Everything runs in your browser. Your images and data never leave your device — no uploads to any server, complete privacy, completely free.
Instantly see your thumbnail in Home Feed, Search Results, Watch Page sidebar, YouTube Mobile app, and Shorts feed.
Add up to 2 lines of text directly on your thumbnail with full control over font size, weight, color, shadow, background style, and 9-point position grid.
Upload two different thumbnails and compare them side by side in a real YouTube card grid to pick your winner.
Toggle NEW, LIVE, HD, CC, 4K corner badges. Set duration badge position. Add playlist labels and sponsored tags.
Switch between YouTube's light and dark UI themes to ensure your thumbnail stands out in both environments.
Enable the safe-zone grid to check that critical text and faces won't be cropped by YouTube's thumbnail masking.
See exactly how your thumbnail looks in the YouTube mobile app with a realistic phone frame, header, and chip filters.
Download a high-quality PNG of any preview context with a single click — no watermarks, no account required.
