Creating YouTube thumbnails with AI

Creating an engaging and professional thumbnail for your YouTube videos can be a cakewalk with the help of the Fliki AI thumbnail maker. AI can simplify the design process, allowing you to create attention-grabbing thumbnails in just a few steps. Here's how you can do it:

Step 1: Create a design file

Select the "Files" option from the top panel. Click on the "New File" button. Select ‘design,’ enter a file name, and select the language. Choose the aspect ratio as landscape (16:9) to match YouTube's recommended thumbnail size. Under "Start With," select "thumbnail," then hit "Submit."

  • Media Layers: Include additional images or graphics to enhance the visual appeal of your thumbnail.
