CapCut Desktop is an AI-based creativity and editing webpage all in one, easy to use. It provides you with an opportunity to create your own images, edit them on the spot, and prepare them for your YouTube channel, all under a single roof.

CapCut can provide creators with all the tools to make their videos shine, and creators who appreciate speed and quality are likely to take advantage of it.


Key Features of CapCut’s AI Image Generator


Text-to-image creation: The CapCut AI image generator can automatically transform the written concepts to real images in real-time. All one has to do is type what one desires, like A smiling creator with a bold red background and a big YouTube logo, and the tool creates it in a few seconds. You also have the option of uploading a sample photograph to serve as a fashion guide so that you can attain the required appearance.

AI models for flexible results: CapCut has several AI models, each with several degrees of realism and creativity, including Image 4.0 (Seedream 4.0), 3.1, 3.0, and 2.0 Pro. Image 4.0 produces extremely detailed, realistic images, and Image 3.1 and 3.0 are superior to artistic or stylish thumbnails.

Background and composition control: With the background remover, you can either isolate your subject, replace the backdrop, or add a contrasting color to have your thumbnail stand out.

How to Create Unique YouTube Thumbnails in CapCut Desktop


Step 1: Describe Your Thumbnail Vision

For this project, open CapCut Desktop and create a new project. In the left panel, select "AI media" and "AI image". Here is where you start being creative. Put in the prompt box a clear, detailed description of what you want your thumbnail to be. As an example, you might enter the following query: A bold YouTube thumbnail with a person pointing at a laptop screen and a glowing background.

When you have a reference image (i.e., the style guide to your channel or the color theme your brand has), you can upload it. This can assist the AI of CapCut to follow your creative direction and deliver results that are consistent with your channel persona.

Step 2: Select an AI Model and Aspect Ratio

Once you type your prompt, you have to select an adequate AI model and aspect ratio. In the case of YouTube thumbnails, 16:9 is the best option, which will make sure your design fits any size screen.

Then there are other models available to your choice, such as Image 4.0 (powered by Seedream 4.0) to get ultra-realistic results, or Image 3.1 to get the creative and stylized results. Experiment, and find which one you can best express in. This freedom allows you to be consistent with the visual feel of your channel and, at the same time, keep it updated.

Step 3: Generate and Refine

Click Generate and leave the AI of CapCut to do its job. It will give you four image results in a matter of seconds, depending on what you prompt. Read through all of them and choose the one that fits your video theme better.

After selecting, customize your photo using the editing filters of CapCut. Brightness can be changed, filters can be used, and contrast can be adjusted to give a harsher and more dramatic appearance. Overlay text writing catchy stuff like Top 10 tips or Must watch! with the fonts and effects provided by CapCut.

In case the design requires a simpler look, the background remover will help remove the distractors and focus on your primary object. It is also possible to add stickers, logos, or frames to make it even more attractive.

Step 4: Export and Upload

On finding your thumbnail is looking perfect, just click the 3-line menu, which is at the top of the editing panel, and then choose "Export still frames". Select your own format - JPG or PNG - and resolution (maximum 8K to obtain high-quality images). This is followed by clicking the button Export so that it may be saved on your computer.

And so your AI-made thumbnail is ready to use. You can upload it to YouTube under its upload options. To further promote your channel and get people to click on an attractive thumbnail that attracts attention, you will have intelligent design features, which will help you with CapCut.
