thumbishChoose your thumbnail in Thumbish’s free preview tool, enter your video title and channel name, and add an optional logo. Switch device and placement to inspect the same image in Home, Search and Suggested layouts. The images stay in your browser and the surrounding videos are illustrative.
Use the title you intend to publish
A thumbnail and title work together. Upload the final JPG, PNG or WebP and paste the intended video title rather than placeholder copy. The preview accepts up to 100 characters and visually truncates long titles within the simulated card.
Add your channel name and logo to see whether the image feels coherent with your identity. Set the duration label to inspect its overlap with your composition. Without your own image, the preview shows a clearly described sample.
Compare Home, Search and Suggested
Home displays the video among neighboring thumbnail cards. Search emphasizes the title and accompanying metadata in a row. Suggested uses smaller cards alongside a simulated watch area. Each makes different composition details easier or harder to read.
Switch between desktop, tablet and mobile, and try both light and dark mode. Do not rely on fine text that only reads at full size. Look for one recognizable subject and a clear relationship between the image and the title.
A repeatable visual review
Compare two exported versions one at a time using the same title and device setting. Keep the video promise constant so you can see which composition explains it more clearly. This tool does not perform live A/B testing or measure audience behavior.
- Check whether the main subject survives the mobile view.
- Look at the bottom-right corner under the duration overlay.
- Read the visible title fragment and check that it makes sense.
- Check the channel logo crop and overall contrast in both themes.
Understand what the simulation shows
YouTube layouts vary by viewport, account, locale and interface updates. These previews are representative layouts rather than a live connection to your channel. View counts, dates and other videos are samples.
Your thumbnail and logo are decoded locally and displayed using browser object URLs. The tool does not upload those files or assign a performance score.
Frequently asked questions
Can I preview a thumbnail with my title and channel logo?
Yes. Add your thumbnail, enter your title and channel name, and optionally choose a logo. The images stay in your browser.
Can I check mobile, tablet and desktop layouts?
Yes. Switch between three device views and Home, Search or Suggested placements. Light and dark modes are available. These are illustrative layouts; the actual YouTube interface can vary.
Does this predict clicks?
No. The preview helps you inspect readability and your title-thumbnail pairing. Surrounding videos and view counts are samples.
