Clari-Fi uses blurring to simulate the challenges of viewing small icons, images and text on mobile screens


Pro version of assessment tool (Beta test v1)

This page can apply a calibrated level of Gaussian blurring to your e-commerce image(s), which you can select using the ‘choose files’ button at the bottom of this page. The images will be processed locally by your computer, they are not transferred over the Internet. You can select any number of images to process, and the results can be downloaded as a PDF.

If you haven’t done so already, please read the introduction, which includes a summary of the assessment process, and also describes how the Clari-Fi Check Levels are calibrated to population data.

Initially, this tool will run in ‘free demo’ mode, which will add watermarks to the images. These watermarks can be removed by entering a licence key, which can be purchased by emailing A PowerPoint version of Clari-Fi Pro is also available to download, and this uses the same licence key.

By default, this tool uses a level of blurring that corresponds to a thumbnail size of 16 x 16 mm, which is typical for a mobile search results page. This can be changed using the drop-down menu below.

This service is designed for desktop use only.
