YouTube Thumbnail Preview by Mivi

Preview your custom thumbnails directly on YouTube to see how they'll look before uploading

Test your Thumbnails in Real Time directly on YouTube! Step 1 - Upload your Thubnail to the extension. Step 2 - Add your Title & Chanel Name! Step 3 - Click "Apply Preview" to see your Thumbnail as it will look on YouTube! You can reset the Extension and Try Multiple Thumbnails! You can try different titles! Run a quick test to see how your Thumbnails will look on any Youtube Page! To see how it will look on Mobile you can adjust your screen to see how it will show up on a device with a vertical screen resolution! YouTube Thumbnail Preview by Mivi will replace a random video's Thumbnail/Title/Channel Name so you can scroll up and down and see how your Thumbnail stacks up against the competition! To Use the Features you must have a subscription. After you have created your subscription, refresh the YouTube Home page if you were on it already so extension refreshes with your account. After that upload and start clicking! Change the full page to have your Thumbnail if you want! Each click executes one change to a random video, the more times you click the more videos will change. Sometimes it will "change" a video it has already changed so some clicks might feel like they haven't done anything, that is because it is set to change a random video to recreate the feel of your own Thumbnail being displayed on YouTube! The benefit is that you get to use your own home page and YouTube profile so you can get a feel of how it will actually look. If you were to use a generic YouTube replica background the videos that are next to your testing extension would have thumbnails that are not catered to your actual profile. With this extension you get to see how your extension will look in the context of your profile and your preferences which is key to having a good benchmark! GOOD LUCK WITH YOUR VIDEOS!
