Everyone today is vying for consumers’ attention. Brands and marketplaces are all searching for a competitive edge in their direct-to-consumer channels to win and retain brand loyalty. In this crowded market, marketing teams recognize that a visual mobile and web experience is mission-critical for enhancing conversions, revenue, and customer loyalty.
In my last post, I introduced FUIF, a new, free, and universal image format I’ve created. In this post and other follow-up pieces, I will explain the why, what, and how of FUIF.
Even though JPEG is still the most widely-used image file format on the web, it has limitations, especially the subset of the format that has been implemented in browsers and that has, therefore, become the de facto standard. Because JPEG has a relatively verbose header, it cannot be used (at least not as is) for low-quality image placeholders (LQIP), for which you need a budget of a few hundred bytes. JPEG cannot encode alpha channels (transparency); it is restricted to 8 bits per channel; and its entropy coding is no longer state of the art. Also, JPEG is not fully “responsive by design.” There is no easy way to find a file’s truncation offsets and it is limited to a 1:8 downscale (the DC coefficients). If you want to use the same file for an 8K UHD display (7,680 pixels wide) and for a smart watch (320 pixels wide), 1:8 is not enough. And finally, JPEG does not work well with nonphotographic images and cannot do fully lossless compression.
I've been working to create a new image format, which I'm calling FUIF, or Free Universal Image Format. That’s a rather pretentious name, I know. But I couldn’t call it the Free Lossy Image Format (FLIF) because that acronym is not available any more (see below) and FUIF can do lossless, too, so it wouldn’t be accurate either.

Responsive design turns 8 this year, and to celebrate, we asked experts from across the web industry a simple question: what does responsive design mean to you and your work, in 2018?
I’m fascinated by their answers. As many state, the technical aspects of responsive design – flexible grids, flexible media, and media queries – are more-or-less well understood, eight years in. But those simple-sounding ideas about CSS are still having far-reaching effects, which extend far beyond code. Below, you’ll read about responsive design’s impact on how individuals, teams, and entire organizations work and think. How should we model our content, now that it is responsively adapting to fit new and different contexts? How in the heck should we be prototyping and testing responsive designs? How can our teams and workflows be structured to better accomplish this new kind of work?
In this part, I'll show you how to implement our new responsive images solution, which enables you to optimize the image you deliver based on the requesting device's resolution and the available dimensions. This new feature can help you to simplify the many complexities of creating multiple variants of every media assets, with on-the-fly manipulation and fast delivery through the CDN.
