How to set up an interactive wireframe with Justinmind

Learn how to set up an interactive wireframe in this tutorial. With Justinmind, you can not only start your wireframe from scratch, but also from an image, another Justinmind prototype (.vp) or a pre-loaded prototype example.

Open Justinmind, and choose between the Beginner and Expert modes available:


First of all, select the option File > New > Prototype or click “Create a New Prototype” in the Welcome window.

Select a device in the device selector, which lets you define the type of prototype you’re about to build, i.e. a web prototype, a mobile prototype for iPhone, iPad, etc. Some of the features in Justinmind will be configured depending on your selection, and special events and simulation will adapt to the type of prototype. The examples on the following screen will also be different depending on the option selected on this window.

Now click ‘Next’ and this window will show up:

Create interactive wireframe from empty template

You’ll need to choose one of the following options:


This option creates an empty prototype for the device chosen in the previous screen.

Create interactive wireframe from images


If you selected iPhone or iPad as a device, the images will be resized inside Justinmind to the correct resolution. Retina resolution images won’t lose quality when displayed in a retina display.

  1. Add image file. Using this option, you will start your prototype with one screen for each image file. This is useful when different web pages have different designs. You also have the option to add additional images inside Justinmind.
  2. You can choose to embed the image in the prototype or make a link to the images you are working on. When linking the image, every modification to the image made outside Justinmind will be updated in your prototype without you doing any extra work. If you decide to link the images now, you still have the option to embed the images later in the prototype.
  3. Delete all. This option clears all the uploaded images.

Example Prototype

  1. A list of pre-loaded example prototypes will appear for each device.  These sample prototypes are useful to learn how to use Justinmind.
  2. A brief description explains what is included in the selected example.


By selecting this option, you can open a new project using an existing .vp file. This option can be used to convert a prototype from a device to another (for instance, converting a web prototype into a mobile prototype).

Once you have chosen how you want to start building your web or mobile prototype, press Finish. The dialog will close and the workspace with all the tools and palettes will be displayed.

    How do I publish prototypes online on my own server/host without using usernote?

      There’s an issue regarding this matter. Hopefully it will be fixed soon!

    JustInMind doesn’t support Windows Phone apps prototypes?

    What is the file extension that JustinMind uses for saving files of the work that you have done?

      The prototypes are saved in .vp format (similar to .rar). Prototypes can be exported as HTML or images.

    The settings for the prototype do not produce what I would expect for a Samsung Galaxy S5 phone. The specs read that the pixels are 1080 x 1920. What should they be to render properly and not weirdly. The provided Android phone choice is not correct.

      Because the Samsung Galaxy S5 has a high resolution and high amount of pixels per inch (PPI), you will have to have the resolution be lower than 1080×1920. To prototype it correctly for that device, you should have the resolution set to 360×640.
