Create polished device mockups from screenshots

What is a device mockup generator?

A device mockup generator helps you present app or website screenshots inside realistic hardware frames. Instead of sharing a flat screenshot, you can frame your UI in a phone, tablet, or laptop shell to provide context and improve perceived quality. This is useful for app store listings, social creatives, product launches, and client presentations where visual clarity matters.

Features for screenshot framing

Build clean presentation visuals in minutes.

1. Device frame mockups: Wrap screenshots in realistic device frames for product and marketing visuals.
2. Browser-based workflow: Create a screen mockup online without installing desktop design tools.
3. Fast visual presentation: Turn raw screenshots into polished assets for launch pages and social posts.
4. Multiple use cases: Useful for app store previews, changelogs, documentation, and promo banners.
5. Export-ready assets: Generate framed screenshots you can reuse across web, decks, and ads.
6. Simple setup: Upload screenshot, choose a frame, adjust layout, and export quickly.

How to create a Dimmy mockup

Create a framed screenshot in three steps.

1. Upload your screenshot: Start with a clean app or website screenshot at a suitable resolution.
2. Choose a device frame: Select a phone, tablet, or desktop frame that matches your target platform.
3. Adjust and export: Fine-tune placement and background settings, then export your mockup asset.

Tips for better device mockups

Keep framed screenshots clear and consistent.

1. Use high-resolution screenshots: Sharper source images produce cleaner exports and better presentation quality.
2. Match frame to platform: Use iOS-like frames for iOS views and Android-like frames for Android views when possible.
3. Keep spacing balanced: Avoid overly tight crops so the device frame and content both remain legible.
4. Stay visually consistent: Use similar frame styles across a series to keep product storytelling coherent.
