New Image File Format: FUIF: Why Do We Need a New Image Format

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.

 New Image File Format: FUIF:Lossy, Lossless, and Free

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.

10 Website Videos Mistakes and How to Solve Them

It should come as no surprise that video use on the internet is exploding. You can see the dramatic growth of video on the average site in this SpeedCurve blog post.

With the growth in video comes greater bandwidth use, which is not only costly for your IT budget, but for your visitors as well. Beyond the expense, there is the user experience to consider. The heavier the page, the longer it will take to load, and the greater likelihood visitors will abandon your site. Page load speed is also an important factor in SEO ranking, so clearly video is something we need to take seriously and get right. Video is challenging, presenting terms still unfamiliar to developers - like codecs, bitrate and adaptive bitrate streaming. As a result, mistakes are being made in video implementation.
