Frequently Asked Questions

What size are YouTube thumbnails?

YouTube thumbnails should be 1280 x 720 pixels with a 16:9 aspect ratio. This is the standard size that YouTube recommends for optimal display across all devices—from mobile phones to smart TVs. Our generator outputs exactly this size, so your thumbnails are ready to upload immediately.

Can I generate multiple thumbnail options?

Yes! Our AI generator creates up to 4 unique thumbnail variations per request. Each uses a different visual approach—close-up shots, split-screen layouts, bold text emphasis, and minimalist designs—so you can A/B test which performs best for your audience.

Will it output 1280x720 PNG?

Absolutely. Every generated thumbnail is automatically resized to exactly 1280x720 pixels and exported as a high-quality PNG file. PNG format ensures crisp text and no compression artifacts. Ready to upload directly to YouTube.

Do you store my generated images?

No. Generated thumbnails are created on-demand and delivered directly to your browser as base64 data. We do not store, save, or retain any generated images on our servers. Download them immediately after generation.

How do I A/B test YouTube thumbnails?

Generate 4 different thumbnails with our tool. Then either: 1) Use YouTube's built-in A/B testing feature (YouTube Studio → Content → Select video → Test & Compare), or 2) Manually swap thumbnails every 3-4 days and compare CTR in YouTube Analytics. Our multi-variant output is designed specifically for this workflow.

How many words should be on a thumbnail?

Keep text to 2-5 words maximum. Remember that YouTube previews can be as small as 120x68 pixels on mobile—your text needs to be readable at that size. Our generator enforces a strict 5-word limit on text overlays to ensure your thumbnails remain readable.

Why do AI-generated thumbnails sometimes look weird?

AI image models can struggle with: 1) Text rendering (letters may be garbled), 2) Human hands (extra fingers), 3) Complex faces (distortion). Our tips: Keep text overlays very short, use descriptive prompts for subjects, choose 'minimalist' style for cleaner results, and generate multiple variations—usually at least 1-2 of the 4 will be excellent.
