AI YouTube thumbnail generator for your next video
Describe a thumbnail concept, add a reference photo when you need one, and refine the result with YGen. The workflow combines image generation and editing so you can explore a visual idea before deciding what to publish.
Start with what your video actually shows
A useful thumbnail brief starts with the subject and promise of the video. For a camera review, that might be the camera and one visible feature you discuss. For a room makeover, it might be the finished room and a clear before-and-after contrast.
Choose one main idea before generating. A prompt that asks for a face, several products, a chart and a long headline gives you more competing elements to review. Begin with the essential subject and add only what helps explain the video.
From idea to a reviewed download
- Choose a paid plan. Check the image allowance, supported modes and billing period. Leave room in your allowance for revisions, not just one image per upload.
- Describe the image. Include the main subject, background, composition and any short text. Use the idea assistant when you want help developing the concept.
- Add a reference when it matters. Supply a clear image of a person, object or existing design you want the generation to follow. State which details are important.
- Select a format and generate. Choose a landscape format for a landscape thumbnail workflow. Generation time varies with the request and provider load.
- Inspect and edit. Check spelling, likeness, composition and small details. Ask for a focused change instead of replacing the entire brief at once.
- Download and check the file. Review the exported dimensions and file size, and resize or crop if needed. Confirm the image still works as a small preview.
Three ways to begin
A new scene
Describe a concept from scratch when you do not have an image to start from. Be specific about the subject and what the scene should communicate.
A character reference
Use a reference photo to guide a scene with a person or character. Inspect the likeness rather than assuming an exact match.
An existing image
Use editing to explore a new background, simplify a composition or change text. Keep an earlier version so you can compare the revision.
Check the pricing page for the modes and formats included in each plan. YGen also has a native iOS app; store pricing and subscriptions are managed separately from web billing.
Plan your allowance around revisions
A single generation or edit uses 80 sparks. For example, one initial image and two edits use 240 sparks; generating multiple images adds to that usage. Decide how many concepts and revisions you want for each video before choosing an allowance.
Start with one clear brief and inspect the first result. If the overall concept is wrong, revise the brief. If the concept works but one detail needs attention, make a focused edit. More variants do not automatically mean a better thumbnail.
Judge the result in context
Place the thumbnail beside your planned title. Together they should explain the video without promising something it does not deliver. Review the image at a small size, then inspect the full-resolution file for unwanted changes.
After publishing, use your channel data to evaluate the result. Traffic sources and audience composition can change, so a higher or lower CTR alone does not isolate the effect of the thumbnail tool.
Frequently asked questions
How much does YGen cost?
Starter is $15 monthly or $108 billed yearly, equivalent to $9 per month. Image generation requires a paid subscription. A single generation or edit costs 80 sparks; requests for multiple images consume more. Review plan allowances and features before subscribing.
Can I generate without a reference image?
Yes. Describe the scene you want to create. A reference photo is useful when a person, object or existing visual should guide the result, but it is not required for a new text-to-image concept.
Can I put my own face in the image?
Use a clear reference photo in the character workflow and describe the scene. Review the generated likeness and details before using the image. Available modes and formats depend on your plan.
Are all downloads exactly 1280 by 720 pixels?
No. Dimensions depend on the selected format and image model. Check the exported image and crop or resize it if needed for your upload.
Does YGen guarantee a higher CTR?
No. YGen helps create and revise images. Performance depends on the video, title, audience and distribution. Evaluate a thumbnail with your own channel data instead of treating AI generation as a guarantee of growth.
Can I revise a generated thumbnail?
Yes. Use AI editing to describe a change to an existing image. Edits consume credits. Keep your preferred earlier version and inspect the complete revision before selecting it.
