Device Mockup Generator

Frequently asked questions

How do I use mockDash?

Drop or click to upload any screenshot, pick a device frame (iPhone, Browser, or MacBook) and a color style (Dark or Light), then hit Download PNG. The framed image is rendered at 2× resolution for sharp, retina-quality output — no account needed.

What is a device mockup generator?

A device mockup generator wraps your screenshots in a realistic device frame — like an iPhone, browser window, or MacBook — so they look polished in presentations, portfolios, app store listings, and social media posts.

Which frame should I choose?

Use iPhone for mobile app screenshots, product demos, or anything portrait. Use Browser for website screenshots, SaaS dashboards, or web app UIs. Use MacBook for wide-format screenshots, landing page visuals, or any desktop-first product.

What makes a good screenshot for a mockup?

High-resolution PNGs work best — ideally at the native resolution of the target device. Avoid screenshots with existing browser chrome or device frames already baked in. The cleaner and higher-res the source, the sharper the final mockup.

What image formats can I upload?

mockDash accepts any image your browser can display — PNG, JPG, WebP, GIF, and SVG. For sharpest results use a high-resolution PNG screenshot at native device resolution.

What resolution is the downloaded PNG?

mockDash renders at 2× scale for sharp, retina-quality output. Pixel dimensions depend on the device frame chosen and the size of your screenshot.

Can I use this for App Store screenshots?

Yes. The iPhone frame renders at a high enough resolution for App Store submission. For best results upload a screenshot at the target device's native resolution before framing.

Is my screenshot kept private?

Yes. Your image never leaves your device. All compositing happens on a local HTML5 canvas element — nothing is uploaded to any server, ever.
