Last updated: 2026-10-07 · AI Thumbnail Maker (https://thumbscene.com), operated by KunStudio.
AI Thumbnail Maker makes 16:9 thumbnails for YouTube videos, blog headers and similar covers. You type a title, pick a style and, if you like, add a photo. Automated AI models draw the background art; your exact title is then laid over it in your browser with a real font, so the words are not generated by the AI. Results are produced automatically, are not reviewed by a person before delivery, and can differ from what you expected. By using the site or paying you agree to these terms.
Before you pay you can generate a free preview. The preview is a low-resolution image with a watermark, so you can check the style and the layout of your title. It is not the thumbnail you buy: the HD thumbnail is generated again after payment from the same title and style, so its artwork can differ from the preview. Previews are limited per day (per device, per network address and for the site as a whole). If the daily limit is reached or the preview service is switched off, you can still pay; your thumbnail is then rendered after payment without a preview first. If the image engine is busy or declines a title, you get a message instead and are not charged.
A photo is optional. Add only a photo you own or have the right to use. A photo can be up to 12 MB; JPEG, PNG and WebP work best (HEIC and HEIF may not work on every device). When you select a photo it is uploaded to the file storage of our image provider, fal.ai, so it can be used to build your thumbnail; this happens before you pay. We do not claim ownership of your photo, your title or the thumbnails delivered to you. We cannot promise that an AI-generated image can be protected by copyright or does not resemble an existing work, and we do not promise any number of views or clicks. Please read the Privacy Policy for how we handle data.
Prices are in US dollars and are one-time payments. There is no subscription and nothing recurs. Current prices: 1 HD thumbnail $4.99, and 5 HD thumbnails $14.99. The price is fixed on our server when you check out; the amount is shown by PayPal before you confirm. Payment is taken by PayPal; we do not receive your card number or PayPal password.
After PayPal confirms your payment, we generate the HD thumbnail(s) you bought. All thumbnails in a pack are generated in one go and shown together. They appear on the confirmation screen at 1280x720 pixels, 16:9, without a watermark, each with a download button (PNG). Your title is added in your browser on that screen, so keep the page open until you have downloaded your files. We also try to email links to the HD background art (without your title) to the address you typed next to the PayPal buttons and, if that is different, to your PayPal account address (to your PayPal address if you left the field empty). That email is a convenience copy and is not guaranteed to arrive; the confirmation screen is the delivery. The links point to files hosted by our image provider and may expire, so download and save your thumbnails right away. If PayPal is still confirming a payment, the page checks again automatically for about 5 minutes; after that use the Check again button, or reopen the page on the same device within 7 days. If a thumbnail could not be produced, see the Refund Policy.
Every order comes with a money-back guarantee if we cannot deliver the thumbnail you paid for. How it works, when a delivered thumbnail can no longer be refunded, and the extra rights of consumers in Korea are set out in the Refund Policy, which is part of these terms.
Do not use the service with photos or titles you have no right to use, to make unlawful, deceptive or infringing content, or to disrupt or overload the service. We may refuse or stop an order that breaks these terms; if we do so after you paid and before we delivered, we refund it.
We aim to keep the site running but do not guarantee uninterrupted access. Services we depend on (our image provider, PayPal, Cloudflare) may be unavailable. We may update these terms; the version on this page when you buy is the one that applies, and the date above shows the last change.
To the extent permitted by law, KunStudio is not liable for indirect or consequential loss, and our total liability for an order is limited to the amount you paid for it. Nothing here limits liability that cannot be limited by law, including your statutory consumer rights.
These terms are governed by the laws of the Republic of Korea. If you are a consumer resident elsewhere, this does not remove the protection of mandatory consumer rules of your country. Please write to us first and we will try to resolve the problem directly.
If you are a consumer in the Republic of Korea, the Act on the Consumer Protection in Electronic Commerce applies to your purchase. The withdrawal, refund and refund-timing rules that apply to you are in the Refund Policy, section “Consumers in Korea”. Where these terms are less favourable to you than that Act, the Act prevails.
한국 소비자 안내: 구매에는 전자상거래 등에서의 소비자보호에 관한 법률이 적용됩니다. 청약철회, 환급 시기 등은 환불 정책의 “한국 소비자 안내”에 적었으며, 이 약관이 같은 법보다 소비자에게 불리하면 같은 법이 우선합니다.
