Who is Mocklup for?
Whether you are an indie maker launching a new product, a developer building your portfolio, a designer drafting marketing assets, or a marketer writing high-conversion newsletters, Mocklup is built for you.

Why run entirely in the browser?
By keeping everything local in your browser, Mocklup offers exceptional privacy and convenience. Your screenshots never leave your device, meaning your sensitive or private designs are completely secure. Since there is no remote server processing, there are no upload wait times or subscription walls. Access the workbench instantly, drag your image, and export.
How it works
Three simple steps to craft pristine mockup presentations.
Upload Screenshot
Drag and drop your website page captures or mobile app screenshots directly into the interactive companion workspace.
Customize Layout
Toggle macOS browser chrome or smartphone notch bezels, add solid or gradient backdrops, and adjust the 3D perspective angle and scale in real time.
Export Crisp Image
Your customized layout is converted directly into a clean, high-resolution PNG, JPG, or WebP file, ready to upload to your store or landing page.
Modern Web Standards
Real-time rendering powered entirely by
your browser's native features.
Instead of static templates, your mockup canvas is fully dynamic. Every angle, tilt, shadow, and position offset updates instantly as you drag—meaning no waiting, no stuttering, and zero lag as you perfect your presentation.
When you are ready, exporting your mockup happens instantly, right in your browser. Because the render engine runs entirely on your local machine, there are never any uploads, server queues, or waiting in line—just high-resolution images ready to use in seconds.
Our core product foundations
Our principles dictate every pixel we render and every control we expose.
1. Keeping the Focus on Your Designs
Our editor uses a subtle grayscale UI so your custom screenshot selections remain the central visual focus of the asset.
2. Instant and Frictionless Design
No signup barriers, no persistent overlays, and no subscription banners. Just drag your captures directly into the canvas.
3. Fully Portable Template Standards
Built as an extensible static Astro template. Clean, fully compliant, and ready to be hosted with zero configuration.
