For critiques, design reviews, portfolios, handoffs, case studies, and launch communication built from actual interface screens.
A UI mockup generator for presenting interfaces—not pretending to prototype them.
Compose finished or review-ready interface screens into an image with clear hierarchy. Keep the UI authentic, add annotations or context outside it, and choose framing based on what the reviewer needs to understand.
Start with the job, then choose the frame.
A UI presentation mockup is most useful after a screen exists. It can frame, crop, compare, and explain interface images, but it does not replace the design file, component system, usability test, or interactive prototype.
Browse product & device generators →Use the composition to isolate one state, compare alternatives, or show a short sequence without recreating the interface in a marketing template.
Match the frame to the review question
A frameless crop is best for spacing or component review; a browser or device frame helps stakeholders understand environment. Choose context only after naming the decision under discussion.
Keep annotations outside product truth
Labels, arrows, and explanatory copy should remain visually distinct from the interface so reviewers do not mistake them for real controls. Use consistent annotation color and minimal wording.
Compare states with controlled variables
When showing alternatives, hold scale, crop, and background constant. Changing the presentation between states can bias the comparison and make small UI differences harder to see.
Prepare a UI screen for a useful review
Turn a raw export into a focused decision aid.
- State the review question and select only the screen states needed to answer it.
- Normalize crop and scale so comparisons reflect the interface rather than presentation changes.
- Add device context or annotations only where they remove ambiguity.
- Export at a size that lets reviewers inspect the relevant typography, controls, and spacing.
UI mockup generator FAQ
Can this UI mockup generator create interface components?
No. MockupX presents screenshots and images. Create and edit the interface in your design or development environment first.
Is a UI mockup suitable for a portfolio?
Yes. Pair polished interface views with concise context about the problem, your role, and the decision each screen demonstrates.
Should I include every screen in a flow?
Only when the sequence is the subject. For most presentations, select the few states that show the key decision or outcome and keep them readable.
