SpeedkitPicture (Experimental)

SpeedkitPicture is based on the module @nuxt/image@0.2.0. However, we have created a separate Vue component for it, because at the time of the implementation of the module the component NuxtPicture and the API for generating the images were not yet completely finished, or this module did not yet completely cover our use-case. We hope that with the final completion of @nuxt/image we will be able to remove our component SpeedkitPicture and can use @nuxt/image & NuxtPicture with full functionality.

This is an experimental component that we will offer until nuxt/image is fully feature-complete released. This also means that we will accept bug reports for the SpeedkitPicture component. However, we will not fix bugs that are present in the generator of @nuxt/image.


With the current implementation of SpeedkitPicture we can cover the following functionality:

  • generation of multiple image resolutions (srcset)
  • breakpoint-based differentiation of multiple image resolutions and ratios (srcset + media-rule)
  • generation of breakpoint-based placeholders (different ratios e.g. for mobile portrait and landscape)
  • optimized preloading of critical image resources
  • lazy load of non-critical image resources
  • base path support
  • lazy hydration support
  • load and optimize remote images from custom domains
  • full SEO support


The SpeedkitPicture (Experimental) is used to automatically generate and display different image sizes and/or image ratios for different viewports.

The specified resources can be given by absolute path (static folder) or complete URL. nuxt/image downloads the resources fully automatically and stores the generated and optimized renditions in the destination folder.

  • Type: Array

List of resources used.

Note: If more than one resource is included, the smallest width from the sizes property is taken as the condition for the source e.g. (min-width: 992px). This allows viewport dependent aspect ratios.

Information on property src can be found at here.

Property sizes describes the image sizes in which the resource is to be displayed. Image sizes are comma separated and describe the image width and its dependent viewport width e.g. ImageWidth:MinWidth.

In the following example, two different image ratios are used.

  • landscape.jpg is applied at a viewport of 992px with an image size of 1024px.
  • portrait.jpg is applied below 992px and has two viewport dependent image sizes, at (min-width: 768px) the width 768px and everything below that the width 414px.
  { src: 'landscape.jpg', sizes: '992:1024' },
  { src: 'portrait.jpg', sizes: '414,768:768' }
