A simple way to present screenshots beautifully
Mocklup is a free online tool for turning product screenshots into clean 3D-style browser mockups. It was built for people who need launch-ready visuals quickly — without opening a heavy design app or learning a complex workflow.
Why Mocklup exists
Great products deserve great presentation. A raw screenshot often feels flat in a landing page, portfolio, tweet, pitch deck, or changelog. Mocklup makes it easy to add depth, layout, and background styling so your interface looks intentional and polished.
We wanted a focused tool that does one job well: help you compose screenshot mockups in the browser and export them in seconds.
What you can do with Mocklup
Multi-screen layouts
Present one, two, or three floating browser windows with preset layouts for launches, comparisons, and product storytelling.
Custom backgrounds
Use solid colors, gradients, images, or transparent exports to match your brand, landing page, or social post.
Fast exports
Export PNG, JPG, or WebP at 1x, 2x, or 4x scale directly from your browser when your mockup is ready.
How it works
- 1. Upload a screenshot — drop, paste, or choose an image from your device.
- 2. Choose a layout — pick a single-screen or multi-screen composition.
- 3. Style the scene — adjust background, tilt, zoom, borders, and shadows.
- 4. Export your mockup — download a high-quality image ready to share.
During normal editing, your uploaded screenshots are handled locally in your browser. That keeps the workflow fast and private while you work on your mockup.
