How to create multi-device responsive mockups
This generator helps product teams show responsive design quality in one polished visual. Presenting desktop, tablet, and mobile together is one of the fastest ways to communicate modern product maturity.
- 1
Upload one core screenshot
Use a high-resolution UI screenshot from your app or website and upload it once to generate a full responsive multi-device composition.
- 2
Choose shared hardware finish
Set one consistent device color system so desktop, tablet, and phone frames look like a cohesive campaign set.
- 3
Tune layout & backgrounds
Pick studio/hero/showcase angles, cover or contain screen mapping, spread for tablet and phone, and show or hide each device. Set preview vs export backgrounds — including transparent PNG for compositing.
- 4
Export high-resolution PNG
Download a sharp render (long edge up to 3840 px) for launch pages, case studies, app listings, social posts, and media kits.
Why responsive device sets improve trust
Multi-device layouts prove your product works across screen sizes, reducing buyer uncertainty and increasing confidence for decision-makers, especially in SaaS, fintech, and enterprise demos.

Best source sizes for responsive mockups
Use large source images to keep text clear across all three devices. Export a large master first, then resize for each channel.
| Use case | Suggested size |
|---|---|
| Master source screenshot | At least 1920 px wide |
| Website hero composition | 2000 px+ long edge |
| Campaign master export | 4K export then downscale |
Responsive creative workflow tips
Keep one central UI moment visible across devices so the narrative is consistent. Avoid overcrowded screens that become unreadable on phone frames.
Export multiple angles and test which one performs better for conversion on landing pages and paid campaigns.
Frequently asked questions
What is a multi-device responsive mockup?
It is a single composition showing desktop, tablet, and phone views together to communicate responsive product quality.
Is this responsive mockup generator free?
Yes. The tool is free to use and exports watermark-free PNG files.
Do screenshots get uploaded to your server?
No. Your image is processed locally in your browser.
