Ultimate Thumbnail Maker: Youtube Thumbnail Maker is an Android app for creating thumbnails, channel art, and banners for a YouTube channel. The developer, Nilesh Jain, describes it as a way to make your own designs without hiring a professional designer, and the listing presents it as a step-by-step tool that is easy to use.

Starting a design

To begin, you open the app and choose a background from the built-in selection or upload your own image. The source describes a wide range of backgrounds and states that the developer plans to add more backgrounds and categories through future updates.

Customizing and exporting

Once a background is selected, you can add text, overlays, or your brand logo to personalize the design. When the design is finished, you can save it and share it. The listing says the outputs can be used as thumbnails, banners, or covers.

Other social media formats

Beyond YouTube, the listing states that the app can be used to design artwork for other social media platforms, naming Facebook, Instagram, and Twitter among them. The supplied information does not describe the specific image sizes or templates available for each platform.
