Private beta — numbers above are what the beta offers, not fabricated user stats.
Sound familiar?
The algorithm tests your thumbnail against your last one. Lose that test and the video dies at 2% CTR — no matter how good the content is.
Every preset is built around what actually wins the feed: face-first contrast, readable-at-120px type, one dominant emotion.
Freelancers charge per image and work in queues. A/B testing five variants costs more than some months of rent.
One credit per generation. Test ten variants for the price of a coffee — before your video even goes live.
You’re a creator, not a retoucher. Every thumbnail is a 90-minute detour from the thing that actually grows the channel.
Upload → pick style → generate. Same look across the whole channel, saved as your house style.
How it works
A screenshot, a selfie, a frame from your video. Anything with your face or subject in it.
Six tuned presets — Cinematic, Bold & Vibrant, Minimal Clean, 3D Render, Anime/Manga, Neon Glow — or write your own prompt.
A 1280×720 thumbnail, export-ready for YouTube, in about 15 seconds. Regenerate variants until one wins.
Style presets
Example renders below — every one generated from the same source photo. Your results are watermarked-free and yours to publish.
Moody color grade, film contrast, trailer-poster lighting.
High saturation, punchy rim light, MrBeast-energy pop.
Soft studio light, negative space, finance/education look.
Stylized Pixar-grade 3D avatar of you and your subject.
Sharp cel shading, dynamic angles — gaming and storytime.
Cyberpunk rim glow, synthwave palette, tech-review edge.
Example renders — stylized previews, not user data.
Why ThumbForge
Presets are tuned for the 210×118px feed thumbnail — contrast, face prominence and text-safe zones first, pretty second.
Credit packs from $5. A designer charges $15–50 and takes days. Test everything, publish the winner.
Every render lands at 1280×720 — YouTube’s recommended size. Download, upload, done. No cropping roulette.
Presets are a starting point. Dial in a house style with a custom prompt and save it for the whole channel.
