Hey Product Hunt 👋

I’m Roosvelt, a developer based in Yaoundé, Cameroon, and the maker of Cover Studio.

Why I built it: I also run Portf.app, where people deploy their portfolios. I noticed that many of them used images that looked unprofessional and weren’t very attractive, which hurt the first impression of their work. So I built Cover Studio to help them create professional visuals in about 2 minutes.

How it works

Drop in up to 4 screenshots, or enter a URL and let Cover Studio capture the site on desktop and mobile
Pick one of 16 templates and a brand color (the whole palette is derived from it)
Tweak texts, icon and typography, then export a high-res PNG in the format you need: cover, Open Graph, GitHub, X, Product Hunt or square

Good to know

It’s 100% client-side: your images are never uploaded and there’s no account. The only exception is the optional URL capture, which sends the address you type to a capture service.
The UI is available in English and French, with light and dark themes.
It’s MIT-licensed. New templates, export formats and languages are welcome: https://github.com/roosveltkn/cover-studio

I’d love your feedback: which templates or formats are missing for your portfolio or launches? I’m reading every comment today.
