Frequently asked questions
Is Cover Studio really free?
Yes. It is an open-source project under the MIT license: no account, no watermark and no export limit.
Are my screenshots sent to a server?
No. Import, layout and PNG export all happen in your browser. No image is ever uploaded. The one optional exception: if you capture your site from its address, that address is sent to our capture service, which sends the images back.
Which formats can I export?
PNG files: 2400 × 1500 for a cover, or Open Graph, GitHub, X / Twitter, Product Hunt and square formats, with an optional 2× high-resolution mode.
Can I self-host it or contribute?
Yes. The site is fully static: clone the GitHub repository, run the build and host the generated folder anywhere. Contributions are welcome.
Can I capture my website directly?
Yes. Paste its address: Cover Studio lists its pages, you pick 2 (captured on desktop and mobile) or up to 5 on a single device, and the screenshots land in the gallery. Pages behind a login and sites that block robots can't be captured: import your screenshots instead.
Can I make App Store or Google Play screenshots?
No. Cover Studio makes one showcase image (README, Product Hunt, link previews), not the series of screenshots at the sizes each store requires. Use a dedicated tool for those.
