Each time you upload an image, Duda creates up to 5 reduced-size copies of the image.  DudaOne will then automatically insert the appropriately sized image into the desktop, tablet, and mobile websites, making sure your site visitors always see the correct sized image for their device.

Optimized Image Sizes

Image Type Image Width
Background 1980px
Desktop 1660px
Tablet 1440px
Mobile 600px
Thumbnail 150px

Duda will not increase the size of an uploaded image and will only create images that are smaller than the original uploaded image.

For example, if a 2000px width image is uploaded, 5 new optimized copies will be created.  If a 100px width image is uploaded, no new images will be created.

Maximum Image Size

The total area of an image cannot exceed 3,145,728 pixels.  It is unlikely any of your images will be over this limit, but you can quickly check by multiplying the pixel width by the height.
