ThumbFast
Generate up to 4 YouTube thumbnail variants with consistent face rendering, A/B test them and improve your click-through rate. 5 free thumbnails.
Creating effective YouTube thumbnails takes time — too much time. Thumbfa.st is an AI-powered thumbnail generator built specifically for YouTube creators who want professional visuals without spending hours in Canva.
The concept is simple: you upload a photo of yourself once to create a "Person" profile, and the AI maintains your exact likeness across all your thumbnails. No more inconsistent faces from one generation to the next.
You can also paste a YouTube video URL to analyze the style of a high-performing thumbnail — colors, composition, mood — and draw inspiration from it directly. The tool generates up to 4 variations at once, ideal for A/B testing like the pros do.
Key features include:
- Person profiles: your face saved once, used infinitely
- Inspiration mode: copy any thumbnail's style via URL
- Multiple generation: up to 4 variants in one click
- Native YouTube format: 1280x720 px, PNG export ready to upload
- Built-in pixelization tool: bypass AI restrictions on faces
The free plan includes 5 thumbnails with no credit card required. Paid plans start at $19/month for 80 thumbnails per month.
